- FIG. 3 is a diagram of an exemplary transportation information system 300 including public transportation analyzer 114 and rider analyzer 116 , in accordance with an embodiment.
- Public transportation analyzer 114 can receive public transportation data 140 as input, and provide degradation mode 170 as output.

- Rider analyzer 116 can provide, as output, updated user profile 310 and relevant public transportation route segments 312 .
- Relevant public transportation route segments 312 can be based on updated user profile 310 .
- Public transportation analyzer 114 can analyze historical, current (including real-time), scheduled, and other types of public transportation data 140 .
- public transportation data 140 includes real-time public transportation vehicle location information, public transportation scheduling information, historical public transportation vehicle location information, public transportation stations, public transportation lines, and public transportation available trips.
- Public transportation data 140 can include any relevant information that enables public transportation analyzer 114 to prepare an analysis.
- Public transportation systems can have a schedule which determines at what times public transportation vehicles pass certain stations or time points corresponding to the schedule. As long as the transit network operates according to the schedule, very precise plans for trip requests can be generated. Even if vehicles deviate slightly from the schedule, precise routing can provide useful information to users because the vehicles should deviate only slightly from the precise plans.
- a service provided by a transit network can become degraded even beyond slight deviations from the schedule.
- Degradation including even slight deviations, can be detected by public transportation analyzer 114 and indicated by degradation mode 170 .
- scheduling information is substantially changed based on degradation mode 170 .
- Degradation of public transportation systems can occur in many situations. For example, during, rush hour, buses may not keep up with their schedule because of general traffic or congestion. Buses serving the same line might overtake each other and affect the times at which they arrive, depart, and service each bus stop or reach a point in the schedule. Unpredictable changes that affect the transportation system can cause the operation of the transportation system to depart significantly from the schedule, so that the schedule can no longer be relied upon. Such unpredictable changes can include accidents, rerouting, cancellations, extra trips, dispatcher intervention, and other unpredictable changes. Furthermore, changes in one portion of the transportation system can affect other portions of the transportation system, sometimes in ways that are not immediately apparent to users or even operators.
- Degradation modes can be used to enable different handling by embodiments of a transportation information system.
- Degradation modes can apply to an entire public transportation system/transit network, or part of the public transportation system/transit network.
- a degradation mode can indicate that service is running according to schedule with high precision. Another degradation mode can indicate that service is not running according to schedule, with significant deviations. Yet another degradation mode can indicate that service is not running according to schedule at all, but an approximate frequency of vehicles is still maintained. An approximate frequency of vehicles may correspond to normal operating mode for some agencies. Yet another degradation mode can indicate that service is not running according to either schedule or frequencies (for example, no bus serving a station for 30 minutes where normally a bus serves that station every 10 minutes).
- various services can be provided depending on the degradation mode.
- the way routes are computed can be changed, e.g., the way that scheduling information is determined and provided. For example, when routes are computed according to a schedule and the next bus passes the first station in 10 minutes, that 10 minutes is used as a basis for starting the route.
- the route can be started from the current time, and vehicle frequency used as an expected waiting time.
- a transportation information system can change the way routes (including requested scheduling information 160 ) are displayed, corresponding to the degradation mode.
- routes can be displayed to indicate that timing is imprecise corresponding to the degradation mode, and that scheduling information 160 is computed based on approximate, and not precise, scheduling times.
- a transportation information system can compute and display confidence intervals in the computed timings associated with scheduling information 160 .
- users can be alerted in association with a degradation mode.
- a transit network may supply alerts for service disruptions, but such alerts may not enable a user to predict what affect the alert will have on a planned trip.
- a transportation information system can use such alerts to inform a user of an event, and can also derive and show an alert independently from the transit network alerts (separate from or in addition to showing routes in a different way).
- Alerts may be generated and shown in the following contexts: i) when the user views the map in public transport mode (or just zoomed in enough), ii) when the user views schedules of a station or a line, iii) when the user views a computed route, and iv) while the user is following a previously computed route. Additional techniques and combinations of generating and showing alerts are possible.
- public transportation analyzer 114 can compare real-time vehicle positions or arrival estimations with the schedule. In another embodiment, public transportation analyzer 114 can compare real-time vehicle positions or arrival estimations with historical data for a similar period. The historical data can be collected over time from a transit network if available, or can be collected over time using embodiments of the transportation information system. Such comparisons can enable embodiments to compute how unusual is the current situation, e.g., degradation mode 170 .
- Generating an alert can be dependent on schedule adherence. For example, for Zurich, where schedule adherence is high, alerts regarding degradation mode 170 can be generated when a train is over one minute late (and a severe alert if the train is over 10 minutes late). In contrast, for a bus system somewhere else where schedule adherence is not as high, the corresponding values for generating alerts may be 15 minutes or an, hour, adjustable depending on such factors as the schedule adherence, historical performance, and real-time data for the particular transit network.
- rider analyzer 116 can receive as input public transportation data 140 , user data 130 , user profile 150 , and output from public transportation analyzer 114 . Rider analyzer 116 can then analyze the inputs and generate an updated user profile 310 , including relevant public transportation route segments 312 .
- Temporal travel patterns of a user may include the user traveling at the same time of day.
- Locality travel patterns of a user may include the user traveling with the same service, though not necessarily the same trip every day.
- rider analyzer 116 can identify a cluster of route segments in a transit network that is relevant to a user, and generate an updated user profile 310 that assigns those route segments to updated user profile 310 .
- locations and times of day can be assigned to a user profile.
- a user's relevant route segments can be automatically detected based on the user's user profile 150 .
- Updated user profile 310 can be generated based on detecting features of the transit network local to the user.
- the local transit network can be segmented and clustered into used and unused services for that user.
- Clustering can be done locally (similar routes, as defined by vehicle type, route, etc., up to mild variations, including different times of day).
- Clustering can also be done temporally (services running along a similar route, or sharing similar start and end points, at similar times of the day over time).
- the route segment clusters can then be used to identify relevant public transportation route segments 312 and other information that may affect the user's trip.
- Relevant public transportation route segments 312 and other information can be provided to the user. For example, relevant public transportation route segments 312 may be displayed on a screen of a computing device for the user. Relevant public transportation route segments 312 and other information can be stored in updated user profile 310 .
- using updated user profile 310 can provide various applications.
- Personalized nearby public transportation information can be enabled for the user. For example, in one embodiment, nearby stations, lines, and trips can be ranked according to the user's profile.
- public transportation service alerts can be personalized to a user based on deduced commute routes, regardless of an exact time of travel.
- Alert severity can be customized based on an importance to the user. For example, a mild delay in a station outside of the user's area may still lead to severe delays on a service relevant to the user. Accordingly, the user is alerted even though it may not have been apparent to the user that the mild delay in a station outside of the user's area would have led to a delay that affected the user.
- routes that the user is not taking can be suggested to the user by analyzing that such routes fit the user's profile or provide benefits. Users may not always know all the transit systems around them or know the fastest route using a transit system. In one example, a suggested route may be faster than the user's currently chosen route. Other benefits may be based on other criteria, such as providing routes having fewer connections, using a rail transportation system instead of a bus, and so on.
- an alert is generated when a user is taking a vehicle that does not fit the user's profile, or is otherwise an unexpected selection for the user based on user profile 150 , updated user profile 310 , or both (e.g., going on a bus that differs from the user's usual commute at a time when the user is expected to take another action such as going home).
- a transit system can be personalized for a user by providing known trips for the user (analyzed from user profile 150 , updated user profile 310 , or both).
- a transportation, information system can enable the user to compare previously taken routes to newly suggested routes.
- a transportation information system can provide useful defaults for user routing queries.
- rider analyzer 116 may take note of queries entered by a user and a trip that the user ultimately decides to take. This data may be used to offer suggestions to other users when searching similar trips.
- User profile 150 , updated user profile 310 , or both can enable embodiments to find a reasonable set of from and to locations and relevant times of day for the user.
- user preferences for routing parameters can be learned.
- rider analyzer 116 can determine appropriate connection time buffers, walking speeds, vehicle type preferences, walking distance preferences, and other user preferences by automatic analysis of various data.
- user preferences can be manually configured.
- the use of a user's transportation information may be provided as an opt-in service where a user may indicate in advance his or her approval of use of the user's transportation information.
- FIG. 4 is a diagram of an exemplary transportation information system 400 including routing engine 118 and degradation mode 170 , in accordance with an embodiment.
- Routing engine 118 can receive, as input, user data 130 , public transportation data 140 , user profile 150 , and degradation mode 170 . Accordingly, routing engine 118 can provide scheduling information 160 as output, including an indication of degradation mode 170 .
- scheduling information 160 can include explicit mention of the degradation mode and the level of deviation from the schedule. Scheduling information 160 can also be presented in a way that visually represents the level of degradation or deviation from the schedule. For example, a circle centered on a destination can approximate a range of arrival times using a corresponding diameter, in contrast to a point. Routing engine 118 may display the generated scheduling information to a user (e.g., on the user's computing device). Based on degradation mode 170 , routing engine 118 may alter an appearance of scheduling information 160 .
- FIG. 5 is a diagram of an exemplary transportation information system 500 including rider analyzer 116 , routing engine 118 , and updated scheduling information 520 , in accordance with an embodiment.
- Rider analyzer 116 can receive, as input, user behavior 510 and scheduling information 160 . Rider analyzer 116 can detect discrepancies between routing suggestions, provided in scheduling information 160 , and routes users actually take, provided in user behavior 510 . Rider analyzer 116 can provide the analysis results to routing engine 118 . Routing engine 118 can use the output from rider analyzer 116 to generate updated scheduling information 520 .
- a transportation information system can adapt to user preferences, and provide popular routes that are more consistent with user behavior 510 .
- a transportation information system can provide an indication that scheduling information has been updated, e.g., when generating updated scheduling information 520 . The user can be asked to verify whether updated scheduling information 520 is desirable.
- FIG. 6 is a diagram of an exemplary transportation information system 600 including alert generator 120 and alert 610 , in accordance with an embodiment.
- Alert generator 120 can receive, as input, degradation mode 170 , user behavior 510 , user data 130 , public transportation data 140 , user profile 150 , scheduling information 160 , and vehicle identification 620 .
- Vehicle identification 620 can be determined using various techniques. For example, determining which vehicle a user (passenger of the identified vehicle) is on can involve matching the user's location with real-time data for the identified vehicle's location.
- the user's location can be provided by a Global Positioning System (GPS) feature on the user's portable computing device such as, for example, a smartphone. Other location methods are possible, including wireless signal triangulation.
- GPS Global Positioning System
- the identified vehicle location can be provided by, for example, the transit agencies.
- vehicle identification 620 corresponding to the user's location, can be provided to alert generator 120 .
- Alert generator 120 can generate alert 610 , which can be used in various applications.
- vehicle identification 620 can be provided to various other components of analyzer 110 , including rider analyzer 116 , routing engine 118 , and other components.
- alert 610 can be used to notify analyzer 110 to use a different method of determining the user's location.
- analyzer 110 can determine a user's location based on a position of the vehicle the user is in, according to vehicle identification 620 .
- Position data for the identified vehicle may be gathered using a GPS that functions in tunnels, odometer readings that give the distance the train has travelled, or other methods.
- a transit network may use transponders positioned on the tracks to identify train locations. Even during a detour, the system can determine that the vehicle will arrive at a specific station, information which can be used for locating the vehicle and user.
- Alert 610 can also be used to notify the user that a different method of location detection is being used for the user.
- a user's GPS can be compared with a vehicle's GPS to determine that the user is on a particular vehicle.
- the user can be “checked in” to that vehicle.
- the user may also be given the option of manually “checking in” to a vehicle.
- the user can send the vehicle information to other users who can be kept informed of the user's progress via that vehicle's progress.
- alert 610 can be used to provide various information to the user. In another embodiment, alert 610 can be used to provide various information to analyzer 110 . Alert 610 can warn the user that the vehicle the user is on is about to enter an area with no cellular signal or no GPS signal. This is useful, for example, if the user is on the phone during a telephone call or using data provided by the cellular signal or GPS signal. Alert 610 can notify the user that analyzer 110 may not be able to provide trip advice while the user is in the tunnel or otherwise without a data signal, GPS signal, or both.
- Alert 610 can be used to notify analyzer 110 , the user, or both when the vehicle the user is on is about to reach the user's stop. Alert 610 can be used to alert the user if the user is going to miss a connection on a planned trip.
- Alert 610 can be used to notify other people regarding the user's status. For example, a user's friend who is going to meet the user can be notified of the user's progress on a trip based on the predictions analyzer 110 has for the identified vehicle the user is traveling on.
- Alert 610 can provide basic information about the trip the user is currently on. For example, analyzer 110 can provide scheduling information 160 including a list of upcoming stations and estimated times, similar to that which is often displayed on trams. Alert 610 can provide notifications of this information to the user, e.g., on the user's own device such as a mobile computing device.
- Alert 610 can provide a warning of problems up ahead along the user's route, so that the user can reroute before getting stuck.

- FIG. 11 is a diagram of an application of an exemplary transportation information system, in accordance with an embodiment.
- Users A 1110 and B 1120 agree to meet at a destination 1150 , e.g., a restaurant, using a transit system.
- a 1110 plans his route to destination 1150 .
- As route from origin 1112 to destination 1150 includes portions 1114 and 1116 .
- a 1110 shares his itinerary with B 1120 .
- B chooses to “join” this trip.
- scheduling information and B's scheduling information can be generated based on different forms of travel used by A and B (e.g., their travel preferences).
- A begins the trip at origin 1112 , and once he boards the vehicle at origin 1112 , the actual times of the vehicles he will catch are calculated (e.g., based on best approximations of connection times, degradation modes, etc., as determined by analyzer 110 ).
- B 1120 is informed when to begin his trip so that he will meet with A 1110 at stop 1130 .
- B's route from origin 1122 to destination 1150 includes portions 1124 and 1126 .
- B's vehicle makes a stop at stop 1130 .
- a transportation information system instructs B 1120 such that B 1120 arrives at stop 1130 in time to catch the vehicle that A 1110 is using. Therefore, A 1110 and B 1120 meet on the vehicle, and travel together (for example, along the last leg 1140 of a journey). A 1110 and B 1120 proceed to destination 1150 together, and do not have to ride separately in portions 1116 and 1126 of the trip.
- a vehicle that A 1110 is riding on that travels along a path of As generated scheduling information is identified. The identified vehicle and path are included in B's generated scheduling information.
- a 1110 or B 1120 may experience delays or a deviation from the original scheduling information.
- As scheduling information is updated based on real-time transportation data of B 1120 .
- B's scheduling information is updated based on real-time transportation data of A 1110 . For example, if A 1110 is delayed and there are multiple stops along ifs path, B 1120 may decide to exit a transportation vehicle that B 1120 is riding on, take a coffee break at a particular stop for a time period, and take a different transportation vehicle at a later point in time to join A 1110 at stop 1130 .
- a 1110 is alerted when real-time transportation data of B 11120 deviates from the second scheduling information.
- B 1120 is alerted when real-time transportation data of A 1110 deviates from the first scheduling information.
- FIG. 12 is a diagram of an application of an exemplary transportation information system, in accordance with an embodiment.
- a system can choose different routes, and even modify a passenger's route postfactum, in order to maximize a portion 1250 of the trip that users A 1210 and B 1220 spend together.
- B 1220 if traveling alone or taking a direct trip, would not typically choose to travel away from a destination 1260 .
- B 1220 might choose to go out of his way if that helped him meet A 1210 sooner and allowed A 1210 and B 1220 to spend more time together on the trip.
- A's scheduling information may be adjusted to increase a portion of the trip that A 1210 and B 1220 spend together.
- B's scheduling information may be adjusted to increase a portion of the trip that A 1210 and B 1220 spend together. For example, a distance of B's generated route that includes the path of A's generated route is longer than a distance of another route from B's starting location to B's destination location. In this embodiment, A 1210 and B 1220 spend more time together along the route.
- a 1210 departs from origin 1212 , proceeds along path 1214 to a stop 1230 , then along path 1216 to stop 1240 , and along path 1218 to stop 1260 .
- a 1210 shares his itinerary with B 1220 and B 1220 chooses to join A's trip.
- B 1220 has an option of traveling a more direct route from origin 1222 along path 1223 to stop 1240 .
- B 1220 chooses to spend more time with A 1210 during the trip.
- B 1220 can be instructed when to depart from origin 1222 , and the vehicle in which A 1210 is riding can be identified, so that B 1220 can find A 1210 .
- a 1210 and B 1220 travel together from stop 1230 to stop 1240 and on to destination 1260 .
- FIG. 13 is a diagram of an application of an exemplary transportation information system, in accordance with an embodiment.
- Users A 1310 and B 1320 want to meet at a common location, timed to arrive approximately simultaneously at destination 1340 .
- a 1310 is departing from origin 1312
- B 1320 is departing from origin 1322 .
- the system can determine that As path will take more time, and generate scheduling instructions for A 1310 to depart before B 1320 departs.
- a 1310 travels along path 1314 to stop 1330 , then along path 1316 to destination 1340 .
- the system determines when B 1320 should depart from origin 1322 .
- B 1320 then departs and travels along path 1324 .
- B 1320 arrives at destination 1340 approximately at the same time as A 1310 , meeting A 1310 at destination 1340 .
- A's trip changes or is rerouted for some reason then the system can notify B 1320 , reroute A 1310 , reroute B 1320 , or a combination of these. For example, if A 1310 misses a connection, B 1320 is notified and can be rerouted to meet A 1310 . The system may determine that B 1320 should leave at a later time. Similarly, A 1310 can be notified of changes in B's trip. For example, A 1310 can be notified that B 1320 has chosen to join A's trip, or that B 1320 is expected to meet A 1310 at a certain point. If B's trip changes, A 1310 can be updated and decide whether to be rerouted.
- FIG. 14 is a diagram of an application of an exemplary transportation information system, in accordance with an embodiment.
- Users A 1410 and B 1420 agree to meet at a stop 1430 , e.g., a bus stop, using a transit system, and travel together for a duration of time along their respective routes.
- A's destination is different from B's destination.
- a 1410 has a destination 1452 and B 1420 has a destination 1454 .
- a 1410 plans his route to destination 1452 , staring at origin 1412 .
- A's route from origin 1412 to destination 1452 includes portions 1414 , 1416 , and 1456 .
- A's vehicle makes stops, including a stop 1430 .
- a 1410 shares his itinerary with B 1420 .
- B 1420 chooses to meet A 1410 along his trip.
- scheduling information is generated for B 1420 to meet A 1410 at stop 1430 and travel along a path 1440 together.
- B's route from origin 1422 to destination 1454 includes portions 1424 , 1426 , and 1458 .
- a 1410 and B 1420 can meet on a vehicle at stop 1430 , and travel together until a stop 1450 .
- a and B proceed to stop 1450 together, and do not have to ride separately in portions 1416 and 1426 of the trip.
- a 1410 and B 1420 can separate so that A can proceed to destination 1452 and B can proceed to destination 1454 .
- a 1410 remains in the vehicle and B 1420 departs from the vehicle to ride a different vehicle.
- B 1420 remains in the vehicle and A 1410 departs from the vehicle to ride a different vehicle.
- a 1410 and B 1420 depart from the vehicle to ride a different vehicle.
- Embodiments illustrated in FIGS. 11-14 can be used between multiple vehicle types, including between public transit and personal transportation. If A 1310 is meeting B 1320 simultaneously in FIG. 13 , the system can track when A 1310 gets on the train at origin 1312 , for example. The system will calculate when B 1320 should get in his car, for example, so that B 1320 arrives at destination 1340 at approximately the same time that A 1310 arrives at destination 1340 . This can be extended to any form of traveling such as walking, bicycling, car driving, bus systems, train systems, and any combination of these for routing or meeting en route.
- riders can be alerted as to the capacity of various vehicles.
- the system can notify a user that a bus or train car is full.
- the user can plan to catch the next bus or train car that is not as crowded.
- a transportation information system can determine such information based on information from a transit system, user behavior 510 , and other data that can identify passenger load in a vehicle.
- a transportation information system can notify users of various features of a transit network/system. For example, embodiments can determine that it is raining, and therefore can advise a user which stops have a shelter to avoid the rain. For example, the system can alert the user to get off one stop early, so that the user can wait under a shelter at the earlier stop.
- Embodiments can be used for real-time information in public transportation systems. Users, developers, aggregators, and others can use the information in various ways. Developers/a developer feed can query a subset of the data. An example query can be “arrivals at station X in the next 10 minutes.” Embodiments can provide information with little need to cross reference, and can synthesize many standards across a variety of transportation systems. A snapshot of all the data can be provided, e.g., for an aggregator/aggregator feed. The data can be provided in a consistent format. Data formats can be optimized for aggregation, including a reference to a static schedule and incremental updates.
- Real-time data can be useful for alerting users if a vehicle is late or otherwise deviating from a schedule, rerouting a nip, or knowing that an event affects a user's trip.
- a transportation information system can determine whether parts of a public transit system route lack cellular or GPS signals and offer a user the choice of choosing another route with more reliable wireless signals.
- Embodiments can determine signal dead-spots where there are no requests coming from mobile networks. In high-usage areas, such as major cities, dead-spots may correspond to areas with no signal and embodiments can build up highly localized coverage maps.
- information can be collected where wireless signals are available on public transit systems.
- Real-time location data for a user can be used to convert a statically planned trip (e.g., origin/path/destination) to a precise list of concrete vehicles, times, or both associated with the trip.
- a statically planned trip e.g., origin/path/destination
- Scheduled information can be matched with real-time data, and can provide updates in the form of time increments to a schedule on a per-trip basis.
- Real-time data can include service alerts, schedule updates, location information (e.g., users and transit systems), passenger loads, video camera feeds, user GPS information, and other data.
- Raw data can be made available to websites and other data distributors.
- Embodiments can provide integration for otherwise loosely connected internal systems at an agency, and compensate when the relation of actual traffic versus scheduled traffic degrades over time.
- Morning Commute Marcus lives near Altersheim, Zurich. Route to work: Bus 140 from Altersheim to Langnau then the S4 from Langnau to Zurich HB.
- Marcus gets up and receives an alert on his phone that the bus to the train station is cancelled. Since it is only a short walk to the train, he can just leave a bit earlier and still catch the train.
- Marcus's phone knows when his first meeting of the afternoon is and alerts him when he needs to take the train back to work. He doesn't waste time waiting at the stop and arrives on time.
- Marcus's phone After enjoying the concert they head back to Zurich. It starts raining, so Marcus's phone directs them to a bus stop with a shelter nearby. Both of them are tired after a long day and fall asleep on the train. Fortunately, Marcus's phone knows when they are about to reach the station and an alarm sounds to wake them up.
