It is possible to permit the speed of about 60 km for a tram by reducing the number of contact accidents, since a contact with a person and other traffic media may be eliminated or greatly reduced by setting up an exclusive lane with a fence, a flowerbed, etc. in a downtown area and setting up a tram priority road in a suburb.

Description

The present invention relates to a technology for convenient and safe operation of streetcars and buses that run in urban areas, automatically driving without a driver under cloud AI control, enabling barrier-free boarding and alighting.
Also, the present invention has no tracks and runs on pneumatic tires, so it is similar to a bus. However, it has characteristics similar to a train because it may set a dedicated lane that does not accept other modes of transportation. Therefore, it is called a tram for convenience.

Tramways get in the way of railroad tracks, and electric wires and the like for power supply must be laid around via pantographs for power supply. On the other hand, shared buses run on general roads and interfere with pedestrians and bicycles, so it is difficult to set up barrier-free. In addition, they are often caught in traffic jams and often cannot read arrival times.

The goal is to use automated driving technology to create a situation where there is no need for a driver. As a risk reduction in the event of an accident, autonomous driving is performed by cloud AI control under the following conditions.
・ Limit the speed during automatic operation to low speed.
・ By limiting the driving areas and lanes during autonomous driving, the speed range will be expanded to about 60km.
As a result of the above, accidents that occur with a probability of about 0.01%, whose risk increases as the number of operating units increases, do not cause serious injuries or deaths. In particular, it enables late-night driving and various tasks to be performed automatically.

In downtown areas, the trams should be surrounded by safety fences and flowerbeds, set up traffic lights as necessary, and set up “tram lanes” (they should be slightly wider than the width of the trams. will set up "tram priority roads" to ensure that people and other vehicles do not get in the way of trams.

The bus stop has a gently sloping slope that connects it to the road, making it barrier-free when getting on and off. In addition to people and wheelchairs, delivery robots, cleaning robots, and robot-type garbage collection vehicles get on and off.

Adopt FCV (fuel cell vehicle) or EV (electric vehicle) in order to achieve the goal of zero greenhouse gas as a basic base. By setting up exclusive lanes with safety fences, flowerbeds, etc. in downtown areas and setting up tram priority roads in suburbs, we will eliminate or significantly reduce contact with people and other modes of transportation, thereby reducing contact accidents. This allows speeds up to about 60km/h.
Furthermore, after making the bus stop a retractable type, we will set up a boarding platform with a slope to make it barrier-free.

It is unmanned for safe and secure operation, and is barrier-free, so it can be used by (electric) wheelchairs and delivery robots. Since the stop is set to be a retractable type, if there are no passengers, it is possible to overtake the tram with passengers running in front, and basically there are no stopping trams in the running lane. So, by the time the out-of-control tram pushes the emergency stop button by a passenger, the chance of colliding with the tram ahead is greatly reduced, further reducing the probability of an accident.
In addition, even without tracks, accurate movement is possible with various sensors, and the distance between the vehicle width of the driving lane can be set to the minimum, so the entire space can be used effectively, and the tracks and power supply system can be used. becomes unnecessary.
Even late at night, if you make a reservation in advance with a smartphone or other device and pay the fare in advance, you can operate Tram 1. Also, by making it possible to get off the train in the green area (the area where passengers can stop by pressing the stop button) in the middle of the night, it is not barrier-free, but it is possible to get off near the house.

1 shows an overview of the present invention;

In downtown areas, we have set up safety fences, flowerbeds, etc., set up traffic lights as necessary, and set up "tram lanes". Take care not to obstruct tram traffic.
Moreover, by performing the above setting, the probability of an accident in the event of a failure is greatly reduced, and the traveling speed of the tram can be increased to about 60 km.

In FIG. 1, the tram 1 on the right side is stopped at the stop of the downtown area type lead-in lane 6 on the 1st floor of the building. The tram 1 does not have a driver, and the presence or absence of passengers getting on and off, the occurrence of trouble, the safety of passengers inside the tram 1, etc. While performing with Clyde AI, operate by the cloud AI control. A height adjustment table 4 with an inclined slope is set at the stop to make it barrier-free, so that wheelchairs, electric wheelchairs, home delivery mobile robots, cleaning robots, etc. can board.
There is another reason for tram 1 to stop at the stop in downtown lane 6, and tram 1 does not stop in tram lane 7 except for the emergency stop button pressed by passengers, so it broke down and ran out of control. The probability of rear-end collisions with following vehicles is greatly reduced.

The traffic light 5 is managed by the cloud AI control, and when the tram 1 passes through the downtown area type pull-in lane 6, it operates with a necessary time margin, and the downtown area type pull-in of people and other transportation media. Prevent entry into lane 6. A safety fence 10 is set in the tram lane 7 so that people and other transportation mediums are basically prevented from entering. In place of the safety fence 10, there is no problem in setting a flowerbed or other structures.
Where land is available in the suburbs, a plurality of suburban pull-in lanes 9 and wide barrier-free areas 8 are set up to cover them, and safety fences 10 are set up in tram lanes 7 as necessary. If there are no houses in the vicinity, only the Tram 1 priority road is set without setting the safety fence 10. - 特許庁

The method of boarding is similar to that of an elevator, and for those who do not have a smart phone app or smartphone app, select the place you want to go from the destination display & destination setting board 11 at the stop, press the appropriate button, and the built-in LED lamp will light up. do. When it is crowded and the button cannot be pressed, a person near the destination display & destination setting board 11 presses it instead by calling out ``Please 〇〇 please'' in the same way as an elevator. If you accidentally press the wrong button, you can release the button by pressing it twice within 5 seconds.

The limited express stop 12, the ordinary stop 13, and the express stop 14 are located in close proximity to each other, but by installing each independently, it is possible to separate the passenger groups and shorten boarding and alighting times. Furthermore, by opening the left and right doors of the tram 1 at the station at the same time, one door is for getting off and the other is for passengers (for example, the right door in the traveling direction is for getting off and the left door is for getting on). to shorten
In addition, by using a smart phone, the number of people waiting at each of the express stops 12, ordinary stops 13, and express stops 14, the number of people who have made online reservations, and congestion information on the next tram 1 scheduled to arrive, can be checked in advance, and a stop that is not crowded (where you can sit) can be checked. It becomes possible to select and go.

Regardless of whether it is for recreation or commuting, basically by making an online reservation from a smartphone, the system will make it possible to increase the number of Tram 1 flights (shorten the time interval) during times when cloud AI is congested. In addition, we will build a system that allows you to board by simply holding up your smartphone or by facial recognition.

It is unmanned for safe and secure operation, and is barrier-free, so it can be used by (electric) wheelchairs and delivery robots. Since the stop is set to be a retractable type, if there are no passengers, it is possible to overtake the tram with passengers running in front, and basically there are no stopping trams in the running lane.
