It is important to guarantee the arterial road traffic function in the rush hour.

The paper discusses the common problems encountered in arterial road transformation in the nuclear part of the city and puts forward solutions, i.

Design exploration of the drainage engineering of the urban main roads;

From the dynamic character of the traffic flows on double-direction and four-phase urban main road,this paper builds the optimal model of the offset among all the intersections in order to minimize the average vehicle delay on main road.

The experience of main road plan and design in southern Yangtze area is proposed,which can be consulted by peers.

In TPN system the way which connects the input place and the output place and the total delay is shorter than any other ways is called Backbone.

An approach to determine main air flow affecting stability of tunnels ventilation based on Radial Basis Function neural network;

The necessity and significance of the design of signal coordination control system in urban main roads are represented in the paper, meanwhile, the design flow process of the green wave signal system is displayed.

The necessity and significance of the design of signal coordination con- trol system in urban main roads are represented in the paper,meanwhile the de- sign flow process of the green wave signal system is displayed,according to the i- dea of the design flow process,the design project is obtained,then the design course of the signal coordination control system is explained in detailed.
