Abstract

The invention relates to a method for optimizing the crossing of a two-way road and a one-way road with a reverse bus transportation lane to conduct optimization layout on an inlet lane of the crossing and detecting facilities. Meanwhile, when phase position timing of traffic lights is optimized; for signal timing, the green light signal is not allocated to the bus transportation lane when no vehicle arrives at the bus transportation lane, it can be ensured that two periods are available for buses to selectively pass through the crossing in one cycle when the vehicles arrive at the bus transportation lane, the priority of the buses is ensured to the maximum, and meanwhile the green light time of the crossing can be fully used so that the traffic capacity of other inlet lanes can be improved. A vehicle detector transmits the information of arrival of the vehicles to a signal controlling machine or an intelligent communication terminal, the steering information of the buses is transmitted to the signal controlling machine through the communication technology, so that the signal light timing is changed, and the signal time allocation is optimized.

Description

technical field

[0001] The invention relates to the technical field of traffic roads, in particular to an optimization method for two-way roads and one-way intersections with reverse bus lanes.

[0002] The invention also relates to the technical field of intelligent communication, especially the communication between the vehicle and the intersection signal control machine. Background technique

[0003] Along with the continuous growth of motor vehicles in major cities, in order to ensure the orderly traffic and improve road capacity, many cities are provided with one-way streets. At the same time, in the process of developing public transportation in various cities, in order to ensure the right of way of buses, a separate bus-only lane is opened in the opposite direction of the one-way street to ensure that buses can run in both directions on this road, and to reduce the inconvenience caused by the one-way street to the bus line setting. . Generally, the intersection of t...

Embodiment Construction

[0033] The technical solution of the present invention will be described in detail below in combination with the embodiments and the accompanying drawings.

[0034] In the present invention, the initial signal timing is controlled by a two-phase signal, and the setting method of the two phases is as follows image 3 , turning left, going straight, and turning right at the one-way entrance is a phase, and the two-way entrances that intersect with it are each turning into a phase. There is a vehicle detection device D (C) at the upstream L of the bus lane from the stop line, and the vehicle detection device transmits the detected bus arrival and steering information to the signal controller. The inventive method carries out periodic signal control according to the following steps:

[0035] 1) If it is detected that there is no direct bus arriving on the bus lane, maintain the original two-phase control, otherwise go to step 2).

[0036] 2) The timing scheme of the arrival sign...
