According to loop characteristic of partially urban road network, urban loop-road traffic coordination control system based on the spit-layer parallel cusp catastrophe particle swarm optimization algorithm is proposed. In the system, the area control system is replaced by the loop-road line control system, and the control sub-area is closed loop-road in(More)
Grey planning methods of urban rail transit have been established in valley-city. On the basis of the analysis of valley-city’s definition and characteristics, this paper has studied the network planning’s basic factors of urban rail transit in valley-city, then uses the entropy value method and Grey system theory to establish network planning methods of(More)
