Description
Technical field
The present invention relates to technical field of traffic transportation, passively excellent more particularly, to tramcar signal under a kind of proprietary right of way
First method.
Background technique
With private car's quantity sharp increase of low occupation rate, urban transportation is faced with the problem of getting worse: more
Frequent traffic congestion is added to drastically influence out line efficiency, environmental pollution caused by discharge reduces quality of life.It first develops
Public transport is to alleviate one of the important countermeasure of the above problem.Modern tram has fortune compared with other public transport modes
The advantages that larger, cost of investment is lower, the construction period is short, environmentally protective is measured, therefore more and more cities are just in Program Construction
Tramcar.
The characteristics of how being run according to tramcar optimizes signal time distributing conception along the line, improves tramcar
The speed of service, while weighing the benefit of public vehicles, it is a urgent problem to be solved.Existing method is solving tramcar
When the passive preferential problem of signal, the method as common public transit vehicle is mostly used, tramcar and common public transport are had ignored
The following otherness of vehicle:
1) there are a plurality of routes in same a road section for general public transit vehicle, and departure frequency is high, thus public transit vehicle it
Between time headway it is small, the target optimized in a conventional method all be maximize public transit vehicle green wave band it is wide；And tramcar line
The repeat factor on road is small, and departure frequency is low, therefore maximization tramcar green wave band is wide without practical application value, will cause
The wide wasting of resources of rail electric car green wave band；
2) car-track lane is laid in road center more, does not share lane with public vehicles, and traditional public transit vehicle with
Public vehicles share lane.Therefore, the public vehicles that tramcar can turn left when passing through intersection with identical entrance driveway mutually rush
It is prominent, and the public vehicles that general public transit vehicle will not turn left with identical entrance driveway mutually conflict.
A few methods consider the design of the signal priority towards tramcar, but these methods do not account for tramcar yet
Otherness between common public transit vehicle, while there is also shortcomings.
Disclosing a kind of having ready conditions for multiple requests application No. is 201610324194 patent application document active has
Rail electric car signal priority systems approach, using repeated detection, multiple requests, after each semaphore receives override requests, all bases
Current phase operating condition, current road conditions, give the response of different degrees of, different movements.It is preferential that this method belongs to active signal
Control method has the disadvantage in that
(1) tramcar signal active priority acccess control needs additional detection device, communication equipment and corresponding management
System will increase additional cost；
(2) when two-way tramcar applies for preferential simultaneously, it is difficult to guarantee that two-way tramcar can preferentially pass through friendship
Prong；
(3) using green time or green light is extended, early in peak period to will cause public vehicles on arterial highway serious for bright strategy
It is current to influence public vehicles for delay.
Application No. is 2016103241920 patent application documents to disclose a kind of rail that multi-intersection is coordinated offline electricity
The vehicle mode of priority.This method belongs to cpm signal method for controlling priority, has the disadvantage in that
(1) index chosen is not appropriate enough, it is impossible to ensure that the journey time of two-way tramcar is minimum；
(2) influence of car-track lane laying is not accounted for, car-track lane is laid in road center more, can be with a left side
Turn public vehicles mutually to conflict；
(3) when tramcar Operational Zone line can not be all in the current window of green light, when this method needs the adjustment signal period
Long and split, adjustment signal cycle duration and split can destroy original optimal cycle duration and split, thus
Serious public vehicles are caused to be delayed.
In conclusion the existing method preferential about tramcar cpm signal is less, these methods stress rail mostly
Electric car is preferential, needs to change the split or cycle duration of signal timing dial, and changes cycle duration and split in peak situation
Under can public vehicles be caused with serious influence.
