Whether disconnected tramcar is just late, and priority signal is provided as far as possible for tramcar if late, and normal flow is pressed if on schedule
Determine whether that it provides priority signal, and judge the signal condition of now signal lamp 6 described in crossing, different signal lamp states
Different signal priority schemes is corresponded to different crossing society vehicle flowrates, when being taken by previous tramcar at crossing,
Priority signal can not be provided for latter electric car, when crossing society vehicle flowrate reaches saturation, in order to avoid serious congestion and
Delay, can not provide priority signal, when meeting minimum green light and maximum green light principle, if rail is electric for latter electric car
Signal is green light afterbody, amber light or red light head when car reaches, then extends green light and provide priority signal for it, if tramcar
5 reach when signal be red light afterbody, then green light provides priority signal for it in advance, if extension and green light is unsatisfactory for minimum in advance
Green light or maximum green light principle, the then scheme divided equally using the time, i.e., from the next cycle of the arrival points of proximity to arrival crossing
The red light and green time of each signal period between the point moment extends the identical time, and the total duration of extension is rail electricity
Car reaches difference of the time that starts of next green light at crossing with reaching the crossing time, cycle of extension for reach the crossing time with
Close to the difference of crossing time, with the business of signal period and subtracting 1, when crossing priority controller 3 does not receive one close to message, i.e.,
Tramcar vehicle-mounted 5 does not receive to be indicated by crossing signals accordingly, and tramcar 5 is when by position detecting device 202
Continue to send approximated position message, it is now close for second, processing mode with first close to identical, but apart from the position at crossing not
Together；When crossing priority controller 3 does not receive first, second close to message, i.e., tramcar vehicle-mounted 5 does not receive accordingly
Indicated by crossing signals, tramcar 5 by position detecting device 203 when continue send approximated position message, now for
3rd is close, processing mode with first, second close to identical, but apart from the position at crossing difference, only when tramcar vehicle-mounted 5
When receiving current crossing signals instruction message accordingly, otherwise tramcar 5 could occur by crossing and be stuck in crossing
Constantly send the message of current request.
During the entire process of the tramcar crossing priority, the control of signal lamp 601,602,603,604 is excellent by crossing
First controller 3 sends to intersection signal control device and asked, and realizes the control of signal lamp.
Traffic flow detecting device 1 detects the vehicle flowrate number under the current traffic condition in each track in crossing in the utility model
According to all data are sent into crossing priority controller 3；Approximated position detection means 2 is used to obtain currently close to crossing
Tramcar approximated position information, and will be sent close to situation to crossing priority controller 3；Crossing priority controller 3 connects
After the data and message that receive other equipment transmission, all message and data are parsed according to communication protocol, will
Data and message storage after parsing, and analyzed and processed according to the data and message of storage, sent out to intersection signal control device
Send override requests so that crossing signals state changes.
The utility model detects the current crossing traffic situation of tramcar by position and traffic flow detecting device, avoids
Serious congestion and delay are caused for tramcar signal priority during wagon flow peak period so that tramcar crossing signals are preferential
Control, can realize tramcar in the priority pass at crossing meanwhile, it is capable to take into account the degree of saturation of social vehicle flowrate, raising has
The operation benefits of rail electric car and the service level at crossing.
The utility model is not limited to foregoing embodiment.The utility model expands to any in this specification
The new feature of middle disclosure or any new combination, and disclose any new method or process the step of or any new group
