It is increasingly serious with urban transport problems, first develop the common recognition that public transport has become countries in the world.Public transport
Special lane is an important measures of public traffic in priority, is alleviating urban traffic congestion, energy saving, reduction urban air pollution etc.
Aspect achieves good effect.However common public transportation lane is suitable on the larger urban road of public transport vehicle flowrate.For
The larger urban road of the smaller and social magnitude of traffic flow of public transport vehicle flowrate, social track item number can be caused by opening up public transportation lane
It reduces, the reduction of traffic capacity utilization rate, and is likely to increase the mean delay of public vehicles and the fragility of traffic system；And
Public transportation lane is not opened up, and public bus network operation situation can be caused poor, and then influences the attraction of public transport.
For this purpose, there is researcher to propose a kind of preferential public transportation lane system of interval.Its operation principle is as follows：Two-way traffic or
The rightmost side track of multilane is as public transportation lane, when system detectio is to bus, the social vehicle of bus downstream neighboring trace
The track where briefly No entry bus；And the public vehicles in track downstream where bus can continue to travel,
Or shift to neighboring trace.Between public transportation lane and social track, setting ground incudes brown flasher as pavement marker lamp.Work as public transport
When vehicle enters special lane, brown flasher on basic road completely opens bright between Adjacent Intersections, forbids public vehicles to enter special
Road, a part of section that bus occupies become regular public traffic special lane；And when bus sails out of, due to bus upstream society
Meeting vehicle does not influence bus operation, and pavement marker lamp extinguishes successively as bus moves ahead, and bus upstream is special at this time
Road becomes conventional track, is opened to public vehicles.It can be seen that public transportation lane is a kind of technology dynamically distributing path resource
Means, practice have shown that：Under given conditions, for the preferential public transportation lane of interval compared with conventional road, bus operating speed can
20%-25% or so is improved, and the operation of social traffic is had no significant effect.
The setting method of the existing preferential public transportation lane of interval, can be summarized as following two modes：
（1）Pass through ground or the publication instruction of ground indicator light after trackside detection.This method is typically to be detected by trackside
System detectio reaches to public transit vehicle and ground indicator light is arranged, and enters special lane to limit vehicle, and prompt special lane
On vehicle be driven out to, but this method needs a large amount of trackside facility, needs bus or train route coordination technique, cost higher.
（2）It is issued and is instructed by ground or ground indicator light after GPS detections.This method is detected relative to trackside
More convenient, however, there remains having indicator light and bus or train route Collaborative Control, limitation vehicle enters special lane, and prompts on special lane
Vehicle be driven out to, this method technical difficulty is big, of high cost.
In summary, the setting method of the preferential public transportation lane of existing interval is big except there are technical difficulty, cost of implementation is high
