Description
Technical field
The invention belongs to road traffic control field, it is related specifically to a kind of speed that can reduce intersection parking number and draws
Guiding systems and its implementation.
Background technique
Signalized crossing is the important node of urban road network.Since driver can not predict front cross message
The real-time change of signal lamp blindly can only select speed to travel, and it is too low and miss front green light or speed to may result in speed
It is excessively high, it is just reached before green light starting, is forced ramp to stop, these situations can mean that the increase of intersection parking number.Greatly
The intersection parking phenomenon of amount will lead to the increase of intersection vehicles delay time at stop, and aggravate oil consumption and tail of the vehicle in intersection
Gas discharge.
In China, the LED display of trackside is increasingly used in the publication of traffic information.The traffic information of publication
It specifically includes that road ahead congestion, sporadic traffic events, parking space information etc., yet there are no and guided specifically for speed
Information.
Chinese patent CN105427640A discloses a kind of green wave speed induction of the main line based on mobile terminal GPS positioning system
System and method, but need just to be able to achieve in the case where driver opens mobile terminal GPS positioning always, audient face is relatively narrow and easy
Disperse the attention of driver.Chinese patent CN103198686A discloses a kind of speed induction for reducing vehicle and rushing amber light probability
Control method, this method need to rely on the operating status of vehicle GPS alignment system real-time detection vehicle, however built-in vehicle GPS
Not majority, the overall effect of Induction Control are limited in the volume of traffic for vehicle fleet size.
Summary of the invention
The present invention provides a kind of speed guidance system and its implementation that can reduce intersection parking number, passes through setting
In intersection upstream, the LED display of trackside informs that all drivers can be met with the driving of suitable speed in front cross mouth in real time
To green light and pass through, reaches the stop frequency reduced vehicle at the intersection, reduce vehicle delay, reduce vehicle oil consumption and tail gas
The purpose of discharge.
Technical scheme is as follows:
A kind of implementation method for the speed guidance system reducing intersection parking number, comprising the following steps:
S1 is manually entered the known parameters of speed guidance system operation in human-computer dialogue module and semaphore；
To guarantee that speed guides the normal operation of system, user need to input LED display away from friendship by human-computer dialogue module
The distance L of prong stop line, the upper limit V for guiding speedmaxWith lower limit Vmin；It also needs to input integrative design intersection by semaphore
Scheme, the integrative design intersection scheme include the duration T of signal control period C, number of phases n and each phasegi；
The integrative design intersection scheme of S2, PLC learning signal machine publication；
PLC is received safely by voltage changing module and is exported by semaphore to the voltage signal of signal lamp, and defeated according to semaphore
The duration T of high-low voltage signal identification and tracer signal control period C, number of phases n and each phase outgi, thus real
Existing study of the PLC to integrative design intersection scheme；
S3, PLC judge whether to need to formulate new speed boot policy；
After the completion of study, intersection signal that PLC will have been stored in the obtained integrative design intersection scheme of study and PLC
Control program is compared；
If not storing integrative design intersection scheme in PLC, storage is learnt obtained integrative design intersection side by PLC
Case, and speed boot policy is formulated according to the Learning Scheme of the storage；
If having stored integrative design intersection scheme in PLC, and the integrative design intersection scheme and storage that study obtains
Integrative design intersection scheme it is identical, then PLC continue keep storage speed boot policy and shown by LED display；
If having stored integrative design intersection scheme in PLC, but learns obtained integrative design intersection scheme and stored up
The integrative design intersection scheme deposited is different, then storage is learnt obtained integrative design intersection scheme and covered to have stored up by PLC
The integrative design intersection scheme deposited, and speed boot policy is reformulated according to the scheme newly stored；Meanwhile LED display
Stop display based on the speed boot policy for having stored integrative design intersection solution formulation；
S4, PLC formulate speed boot policy；
S4.1, firstly, distance L of the PLC according to the LED display inputted in human-computer dialogue module away from intersection parking line,
Guide the upper limit V of speedmaxWith lower limit VminValue, calculate speed boot policy in show guide speed time Tv；
S4.2, then, PLC will show the time T of guidance speed in speed boot policyvThe intersection signal stored with it
In control program signal control period C be compared, thus judge guide car fast-growing at and delivery system bootmode；
If Tv>=C, then guide car fast-growing at and delivery system be in all the period of time speed bootmode, under the mode, LED is aobvious
Display screen always show speed；
If Tv< C, then guide car fast-growing at and delivery system be in common speed bootmode, under the mode, guide car
Speed and prompt information alternately display in signal control period C on LED display；
S4.3, after bootmode determines, PLC further calculates guidance corresponding to different moments in signal control period C
Speed；
If guide car fast-growing at and delivery system be in all the period of time speed bootmode, PLC will as unit of a certain speed,
Speed interval division is carried out to guidance speed corresponding to different moments in signal control period C, to form all the period of time speed
Speed boot policy under bootmode；
If guide car fast-growing at and delivery system be in common speed bootmode, PLC will be right as unit of a certain speed
Display guidance speed time TvIn different moments corresponding to guidance speed carry out speed interval division；Signal controls period C
In except display guidance speed time TvExcept period then exported in the form of prompt information, to form the guidance of common speed
Speed boot policy under mode；
S5 issues speed boot policy by LED display；
After the completion of the formulation of speed boot policy, PLC is by MODBUS agreement, using data register address as medium, by vehicle
Fast boot policy is exported to LED display, and LED display issues the speed boot policy.
