Bidirectional segmental green-wave signal setting method for urban main line bus stops

Abstract

The invention discloses a bidirectional segmental green-wave signal setting method for urban main line bus stops. The method includes: for urban main line buses provided with two-stops and large stop spacing, distributing inter-stop crossings in different groups while periodic signal timing is determined, acquiring maximum two-way bus green-wave bandwidth of each group by setting a within-group crossing signal phase difference, and finally regulating stop berthing time to provide two-way segmental green wave between adjacent stops for the buses. Compared with the traditional green-wave setting method using the crossing as a node, the method using the bus stop as a node is more adaptive to operational characteristics of bus and gives the regulating function of the stops to full play; the green-wave bandwidth is not uniform on an all road section any more, green-wave bandwidth of each group is increased, and the buses are allowed to efficiently pass between the adjacent stops.

Description

technical field [0001] The invention belongs to the field of bus signal control in urban traffic, and relates to a segmented two-way green wave setting method between bus stops with relatively large station distances. Background technique [0002] Public transportation has incomparable advantages over other types of transportation in terms of per capita road resource utilization efficiency, energy saving and emission reduction. It has become a long-term development strategy for urban transportation in my country to alleviate urban traffic problems through the priority development of public transportation. In recent years, although public transportation has been developed to a certain extent, the share rate of public transport travel is still low. The average share rate of public transport in most central cities in the country is less than 30%, and the average share rate of small and medium-sized cities is about 10%, which is in line with national needs and national goals.

In recent years, although public transportation has been developed to a certain extent, the share rate of public transport travel is still low. The average share rate of public transport in most central cities in the country is less than 30%, and the average share rate of small and medium-sized cities is about 10%, which is in line with national needs and national goals. There is still a huge gap between them, and it is impossible to effectively guide the transformation of the non-motorized traffic structure to the bus-based traffic structure and give full play to the comparative advantages of public transport.

[0004] The urban main line bus lines are long, and there are many intersections on the driving route. If the intersections are used as nodes and a unified bus green wave is set for the whole line, the bandwidth of the green wave will be affected due to the limitation of individual intersections, which will reduce the overall cost of the main line bus. At the same time, the increase in the number of intersections and the increase in route length will increase the difficulty of signal coordination settings and decrease the accuracy rate
