The computing machine at second step, train supervision center carries out Difference Calculation and obtains differential corrections according to the actual GPS locating information of GPS base station position coordinates and GPS base station; The computing machine at train supervision center carries out differential correcting with this differential corrections to cab GPS locating information before and after the electric car of receiving, calculates the service data of each row electric car; The service data of each row electric car is sent to urban traffic signal control system by train supervision center;
The 3rd step, urban traffic signal control system carry out after traffic control is processed forming signal controlling order to the service data of each row electric car, and are issued to the signal controlling machine at each road junction, complete electric car grade crossing signal and preferentially control.
The present invention further perfect technical scheme is as follows:
Preferably, train supervision center is also provided with electronic chart; In second step, each row electric car service data is carried out coordinate conversion by the computing machine at train supervision center, and be shown on electronic chart.
Preferably, the service data of each row electric car comprises electric car position coordinates, speed, travel direction.
Preferably, in the 3rd step, in the time occurring communication abnormality between urban traffic signal control system and the signal controlling machine at each road junction or interrupt, controlled voluntarily by the signal controlling machine at each road junction, temporarily stop electric car grade crossing signal preferential, until communication recovers normal.
The present invention can save level crossing tramcar checkout equipment and drop into, and has improved the precision of tramcar location, realizes the intellectuality control of tramcar level crossing signal lamp; Can incorporate smoothly new generation of city traffic signal control system, realize tramcar grade crossing signal and preferentially control; Highly versatile, is applicable to the public transit systems of any bus rapid transit form, and can adopt the train that general GPS is located to carry out centralization differential GPS technology upgrading, improves positioning precision.
