1.Bus priority (BRT) control based on RFID

Control model

1.Four modes:Compulsory priority, absolute priority, relative priority, no priority control
2.The combination adopts the priority phase "insertion", the green signal "extension" or the red signal "early break" decision.

2.Architecture layer of Bus priority

LAYER1 Signal system
	PC-client	DATA-server	AREA-server	MAP-server	Algorithm- server

LAYER2 Network
	ITS-network	vedio-network	Internet	Wireless	3G/4G

LAYER3 Controller
	ITS-network		Traffic light

LAYER4 Detector
	Bus	RFID-card	RFID-reader	E-police	Radar	Camera	Internet data

3.Key technologies

Prediction technology of spatial and temporal distribution of bus arrival

Using the data of upstream detection, intersection check-in, traffic situation and release scheme, the arrival position and arrival time of public transport vehicles can be predicted for macro-control and micro optimization.

Decision making technology of bus signal priority request response

The competition and response mechanism of bus priority is designed based on the elements of bus priority level, intersection traffic status and constraints.

Bus priority control signal technology

Based on the bus signal priority strategies such as optimal average delay, optimal bus delay and optimal punctuality, a control model of benefit balance between public transport vehicles and social vehicles is developed.

Phase green light loss time compensation technology

In this cycle or the next cycle, the green light compensation mechanism is applied to the relevant phases, and the impact of the green light compensation mechanism is evaluated.
