- a crossing safety system is described herein that provides immediate safety improvement through the use of active signs and sensors with DSRC/WAVE communications and is directly extensible when vehicles are fitted with units.
- WAVE refers to wireless access in vehicular environments.
- An acronym list is provided at the end of the description.
- OBE Onboard Equipment
- the . vehicles When fitted with Onboard Equipment (OBE) the . vehicles will become aware of the crossing state and/or the presence of a crossing train or other vehicle; The OBE may then choose to alert the driver to the presence of the crossing vehicle.
- OBE Onboard Equipment
- the warning can be timely and directional, avoiding unnecessary driver distraction and inconvenience due to extended waiting times at the crossing.
- a crossing safety system employed in vehicles and infrastructure elements using wireless communication is described herein.
- FIG. 1 A One embodiment of a DSRC system 100 is shown in Figure 1 A.
- Infrastructure at the crossing will transmit messages to OBEs indicating the slate of the crossing.
- a vehicle is fitted with OBE 1 . 01 that is used to communicate with other OBEs 102 via vehicle-to-vehicle (V2V) communications, and RSEs 104 via vehicle-to-infrastructure (V2I) communications.
- V2V vehicle-to-vehicle
- V2I vehicle-to-infrastructure
- the types of vehicles involved in a railway crossing, and which could also include such OBE include cars, trucks, vans, trains, buses, motorbikes (and variants thereof), and pedal bikes. Pedestrians may also be involved.
- the OBE 101 includes a human-machine interface (H I) 106 for driver interaction.
- the HM1 106 may be an audio, visual or haptic interface, or any combination of these. Examples of interfaces that may be used include a touch screen, or a display screen and a keyboard.
- the OBE 101 includes a processor 108 for running applications and providing control.
- the processor may be a microprocessor, DSP, FPGA or other comparable processing device.
- the OBE 101 further includes a satellite navigation system such as a GPS 1 10 for providing the processor 108 with position and time data, and a DSRC radio 1 12 for providing wireless connectivity to other vehicle OBEs 102 and RSE 104 via antenna 1 14.
- TDE Threat Detection Engine
- the TDE in the OBE will decide which warnings, if any, will be issued to the driver.
- the TDE will respond (via the human machine interface) to: 1.
- Road Side Alert messages broadcast messages that transmit a signal using serial data communication, for example one of the SAE J2540 phrases
- the complete set of ITIS codes can be found in Volume Two of the J2540 Standard.
- a TDE in a train may also warn the train driver of a potential danger such as a vehicle parked across the crossing.
- the TDE functions as follows.
- a new message is received 2101 by the DSRC radio 1 12 (shown in Figure 1 A)
- the received message is queued at step 21 02.
- the message type is checked 2103, and if the received message is a BSM then the remote entity (the entity that the message is received from) is pre-qualified 2104.
- P re- qualification is a step to determine whether the remote entity, which can be a train or other vehicle, is threatening, i.e. whether there is a possibility of a collision.
- the checks that are performed at this step 2104 may be one or more of the following: i. Is the remote entity getting closer (determined from heading, speed of present vehicle and remote entity)? ii.
- Closing velocity is based on the respective headings and speed.
- Predicted motion can also be employed. For example motion on a circle may be used where each entity is aware of its radius. iii. Are the two entities very far apart? iv! Are the entities' speeds above a threshold (both or any)? v. Do the trajectories of the two entities cross in the future?
- step 2106 Fol lowing the pre-qualification step 2 1 04, if the remote entity is threatening, then the distance to the collision is determined at step 2106. Following this, it is determined at step 2107 whether the present vehicle is able to stop at high deceleration. If not, then a high level HMl collision warning is issued 2108. If yes, then at step 2 1 08 it is determined whether the present vehicle is able to stop at low deceleration. If not, a low level HMI crossing warning is issued 21 10. If yes, no warning is issued.
- step 21 1 1 it is determined whether the message is an RSA containing a CCI or CCR. If so, then the likelihood of the present vehicle entering the crossing is determined at step 21 12. This may be done as follows:
- step 21 18 the following decision is made: if the likelihood of entering the crossing is high, then an HMI crossing warning is played 2122; if the likelihood is low, then the HMl crossing warning is disabled 2 120.
- the TDE is also used to transmit a BSM 2130 based on the local position handler 21 16, The message is transmitted 2132 using the DSRC radio 1 12.
- a crossing safety system consists of three main equipment types: vehicle, sensor and sign.
- vehicle vehicle
- sensor vehicle
- sign vehicle
- the train and the vehicle are very similar and may be accommodated by the same equipment type in a different mode.
- the sign 104 also includes a processor and a DSRC radio system in communication with the processor.
- Table 1 shows what equipment transmits what messages and what equipment listens to those messages.
- mobile equipment refers to equipment on trains and other vehicles.
- Fixed equipment or units refer to roadside sensors and signs. The functionality executed upon receipt is described in the summary of the connectivity table below.
- Mobile onboard equipment in trains and vehicles announce the train or vehicle 's dynamic position to all via broadcast of BSMs, e.g. periodically with a- rate of a few times per second.
- Mobile equipment may have a positioning service.
- Inbound sensors may announce the presence of the train at the sensor location by transmission of a Crossing Close Request message (CCR).
- CCR Crossing Close Request message
- the inbound sensor continues to transmit this message, e.g. periodically with a rate of a few limes per second while the train is present.
- Transmission may be periodic, e.g. with rale of a few times per second.
- RSAs are transmitted upon the ' occurrence of asynchronous events.
- the fixed units may be programmed with their position and the co-ordinates of the crossing at installation. Otherwise they may determine their position from other wireless equipment in the vicinity of the crossing.
- Mobile equipment determines if a collision could occur. Fixed equipment can still sense the train if the sensing element fails.
- Signs can signal to trains that a vehicle may enter or is stationary in the crossing. This is achieved by the sign first determining the current and likely position of the vehicle and then if necessary transmitting a message that the train can use to determine the state of the vehicle relative to the crossing.
- 1.4 Mobile Units and Signs listen for RSAs
- CCl Crossing Closed Indicate
- CCR Crossing Closed Request
- DSRC is used.
- One benefit for DSRC is that it has a standard way of encapsulating positional information.
- All units in the system can keep a health check on the other units.
- Units may periodically transmit a special message indicating that they are functional. This message may or may not contain status information, and may identify the unit transmitting the message. If this message is not heard by all units then the crossing may enter a fail safe mode, e.g. an active sign may switch into active. mode. Normal operational messages (due to a crossing event) may be used instead of, or in addition to, periodic messages to monitor system health in the same way.
- the equipment of the system as described above can be implemented in a number of ways. Five example scenarios are described below.
- DSRC RSE is installed at inbound 202 and outbound 204 rail sensors and active warning signs 206.
- An active warning sign 206 is then started to attract the attention of approaching motorists, e.g. through visual and/or auditory warning.
- An outbound sensor 204 detects departure of the train 208 and deactivates the sign 206.
- Inbound 202 and outbound 204 sensors are installed in each direction of approach by rail (for clarity, only a single direction is shown in Figure 2).
- an active warning sign 206 is installed in each direction of approach by road.
- FIG. 3 A system schematic of the technology solution for this scenario 200 is shown in Figure 3. Both sensors 202, 204 are connected to DSRC RSE.
- the inbound sensor 202 When the inbound sensor 202 is triggered, it broadcasts a DSRC standard Roadside Alert Message 302 announcing the arrival of the train 208.
- DSRC RSE at the sign 206 receives the broadcast and activates the sign, and it also begins to broadcast a Roadside Alert Message 302 announcing the presence of the train 208.
- the outbound sensor 204 (which may be co-located with the sign 206) detects the departure of the train 208. Once the train has departed, the sign 206 is deactivated and the RSE broadcasts a standard Roadside Alert Message announcing that the crossing is no longer occupied.
- the inbound sensor 202 may also provide information pertaining to the speed and direction of the train 208.
- the speed may be measured in a variety of ways known to those skilled in the art including pairs of sensors such as loops, Doppler RADAR, etc. This information may be used to adjust the amount of time that the sign 206 is active, and minimise unnecessary delays.
- DSRC OBE is fitted to vehicles 402 approaching the railway crossing on the road 404. Messages broadcast from the infrastructure 202, 204, 206 are also received by approaching vehicles 402, c and trigger an in-vehicle warning.
- DSRC OBE is installed in locomotives/trains 208 and RSE 602 is installed in active warning signs 206.
- Trains 208 broadcast standard DSRC messages that are received by the RSE 602 at the sign 206.
- the active warning sign is then started to attract the attention of approaching motorists, e.g. through visual and/or auditory warning.
- the sign 206 is deactivated once the train 208 has departed the crossing.
- FIG. 7 A system schematic of the technology solution for this scenario 600 is shown in Figure 7.
- the locomotive 208 broadcasts DSRC standard Basic Safety Messages 702. These messages contain the position, speed, acceleration, heading, size and type of the locomotive.
- the DSRC RSE 602 at the sign 206 receives each broadcast, processes the message and determines when to activate and deactivate the sign, based upon the speed, direction and heading of the train.
- DSRC OBE is installed in locomotives 208 and vehicles 402. Trains 208 broadcast standard DSRC messages that are received by vehicles 402. An i -vehicle warning is triggered if the potential for collision is detected.
- FIG. 9 A system schematic of the technology solution for this scenario 800 is shown in Figure 9.
- the locomotive 208 broadcasts DSRC standard Basic Safety Messages 702. These messages contain the position, speed, acceleration, heading, size and type of the locomotive.
- the DSRC OBE in the vehicle 402 receives each broadcast, processes the message and determines if and how the driver should be warned. Warnings may be based upon the status of the train and the speed, direction and heading of the vehicle.
- DSRC OBE is installed in locomotives 208 and vehicles 1002.
- Vehicles broadcast standard DSRC messages that are received by approaching trains 208. If a vehicle 1002 is stopped across the rail line and the potential for collision is detected then an in-train warning is triggered.
- a system schematic of the technology solution for this scenario is shown in Figure 1 1 .
- the vehicle broadcasts DSRC standard Basic Safety Messages 702. These messages indicate that the vehicle 1 002 is stopped, and also contain the position, size and type of the vehicle.
- the DSRC OBE in the locomotive 208 receives each broadcast, processes the message, and determines i f any part of the vehicle 1002 is obscuring the path of the train 208. If the potential for collision is detected then an audible in-train warning is issued.
- the system described herein includes features that provide redundancy improving the reliability of the overall system. More specifically, redundancy is introduced when two or more of the scenarios as described above are implemented simultaneously.
- a communication system 1200 that includes the communication equipment as described above in the five scenarios. Dashed connections shown offer redundancy in the system and although the receiver is not the direct target of the message the recei ver can increase its confidence that the system is operational through reception and in some cases improve safety even further.
- the sensor-to-vehicle RSA link allows the approaching car 402 to understand that the crossing is closed even if a message from the sign 206 has not been received.
- FIG. 1 A preferred embodiment using J2735 BSMs and RSAs is shown in Figure 1 3. Standard compliant SAE J2735 and SAE J2540 messages are employed. SAE .12735 is used for over the air communications. OBEs (on any moving vehicle) transmit and receive J2735 BSMs.
- a sign upon receipt of a CCR or BSM from a train closes the intersection via transmission of a CC1. This message may be heard by all OBEs (including trains). If an approaching vehicle hears a CCI it knows the crossing ahead is closed (CCIs contain the position of the crossing).
- the approaching vehicle is a car then the driver may be alerted to the presence of a closed crossing ahead. Also the OBE may assess the dynamics of the vehicle and further advise the driver to stop more rapidly or even activate brakes autonomously, or increase brake pressure beyond that applied by the driver. Trains can cause trackside equipment to send a Sensor Active message to the sensor element equipment. A sensor clement, upon receipt of a Sensor Active message or a BSM from an approaching train broadcasts a CCR. The train, other approaching vehicles and the signs at the crossing can hear this message.
- the sensor may receive a CCI. This would allow system integrity checking as it makes the CCR issued by the sensor now subject to closed loop verification.
- the CCR and CCI contain the coordinates of the crossing.
- the timing and position of the train and truck are replayed into a processing unit identical to that inside an OBE.
- the OBE determines its own position from its local GPS service and obtains the position of remote vehicles or trains from receipt of DSRC messages over the air.
- the warning trigger points generated in the examples below are identical to those that would be experienced in the Held.
- the Infrastructure to Vehicle implementation is first considered that applies when either new infrastructure is deployed at a level crossing, or system elements are retrofitted to an existing active crossing and the train does not have an OBE.
- I2V the presence of the train is determined by sensors at inbound and island locations.
- the vehicle must be much further offset from the crossing in order to avoid al l messages. This is because the system is behaving like a virtual boom gate, using track-side sensors only.
- the Train Crossing Ahead message will last for more than 25 seconds in most cases.
- Figure 14 the warnings issued to the driver by the infrastructure elements of the proposed system are shown.
- the driver is made aware that a train is approaching the crossing several hundred metres out from the crossing.
- the driver then receives a further warning when his speed has not decreased sufficiently to stop easily prior to the crossing.
- Table 4 shows the various timing offsets and the warnings (if any) that are induced.
- the truck retardation value is the distance from the crossing of the truck when the front of the train arrives at the crossing. Negative values mean that the train passes through the crossing first.
- Figure 15 shows that in the Kerang incident the truck driver would have received a warning in his cabin with 170m distance remaining to the crossing. This is regarded as enough distance for reaction time and stopping distance.
- Figure 1 6 shows the system evolution at the point of collision. The driver was in receipt of Cautionary Collision Warnings then Imminent Collision warnings. The Imminent Collision Warnings occurred when the driver needed to decelerate at the performance limits of the truck.
- Figure 19 shows that a Cautionary Collision Warning was issued to the driver if the truck was a little later to the crossing but still too close to pass safely behind the train..
- a particularly difficult scenario is that of Benalla.
- the train and truck are travelling parallel to each other with a separation of about 25 m.
- Ahead there is a side road that crosses the track. Only in the last few seconds would the train driver be aware that the truck was about to proceed across the track.
- the scenario is shown in Figure 20.
- the proposed system raises an alarm as the truck driver turns the vehicle into the bend crossing the track. With a few seconds warning the driver could stop the truck as speeds are quite low on this corner.
