Signal Controlling System for Public Transport Priority at Road Junctions

Public transport priority is a must to solve the problem of urban transport. The bus lane and serrate type access may give public buses a priority spatially but not temporally. This article proposes a signal controlling system for road junctions and makes a tentative research on the positioning technology for public transport. Furthermore, it discusses the intelligent controlling strategy in public transport and finds out the possible solutions to defects of the system.
