Description
Technical Field
The invention relates to a tramcar control system at a plane intersection, which adopts a speed grading control method to realize the improvement of the whole transport capacity and the transport speed of a tramcar system and belongs to the field of urban traffic control.
Background
The tramcar is generally laid in the center or at the road side of the existing urban road, adopts a form of sharing the right of way with the existing road traffic, has the advantages of low construction cost, short construction period, energy conservation, environmental protection, attractive appearance, comfort and the like, is very commonly used in western developed countries, and is rapidly developed in China in recent years.
More than 90% of tramcar lines in China adopt a semi-closed right-of-way mode with a closed right-of-way and a mixed right-of-way at an intersection, and the tramcar lines are physically isolated when running on the road section, so that the tramcar lines are prevented from being interfered by other vehicles or pedestrians. When passing through the intersection, due to the fact that traffic flow conflicts in different directions exist, isolation must be removed and the traffic light is used for indicating the traffic. In recent years, tramcar signal priority measures are mature, and most tramcar lines have the capacity of priority passing without stopping at intersections. However, for safety reasons, the tramcar must be decelerated at the intersection, and the tramcar must travel at the intersection according to the regulations of the modern tramcar operation management specification (T-diameter 07001-2018), so that the travel speed of the tramcar at the intersection cannot exceed 30 km/h, and the actual running speed is about 20 km/h.
The braking deceleration of the tramcar is less than half of that of the car, and at the maximum speed, the time required by emergency braking is about 7 seconds and the distance is about 70 m; the time required for braking is about 15-20 seconds, and the distance is more than 150 m. Due to the fact that the braking distance and the braking response time are too long, a driver cannot pre-judge possible conflicts at the intersection when driving at a high speed, and can only drive at a low speed (about 20km/h) when passing through the intersection. The distance between the common intersections in the city is 300-500 m, and the tramcar can only be repeatedly accelerated and decelerated during running due to the requirement of speed reduction of the intersections, so that the travel speed is greatly reduced. The travel speed of the device is only half of that of a subway and the like.
Considering that the maximum speed of the modern tramcar is not less than 70 kilometers per hour, the travel speed is about 15-20 kilometers per hour due to frequent acceleration and deceleration at the intersection and the platform. Compared with other urban rail transit such as subways and light rails, the travel speed of 35-40 kilometers per hour can be achieved under the approximate maximum speed condition, and the difference is close to one time. If a corresponding engineering technical means can be found, the problem that the speed of the tramcar must be reduced at the intersection is solved, the running speed of the tramcar can be effectively increased, the competitive advantage of the tramcar is increased, and the development and popularization of the tramcar are accelerated. The present invention is thus filed.
