This paper presented a concept of real-time road traffic service level in urban arteries and built a real-time evaluation model for urban arteries based on fuzzy comprehensive evaluation.

The Study on Optimal Space Distribution of Loop Detectors on Urban Arterial Road and Prediction of Traffic Flow;

In order to rationally organize the traffic in the area of urban arterial road intersected by multi-inferior roads at T-intersection,a traffic organization method with channelized traffic design and signal coordinated control was presented,based on the investigation and analysis of the characteristics of the above area.

The dissertation catches the urban arterial road as studying object, makessome researches on the urban main road traffic organization and optimization fromtwo aspects: t.

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.
