With the development of the urban economy, the size of the cities in China have developed rapidly, at the same time increasing traffic demand of urban residents, which brought the traffic demand and supply contradiction. Direct consequence of urban traffic congestion, traffic order and chaos, traffic accidents are frequent. At the Intersection, the situation is even more grim. Based on our national conditions of mixed traffic flow, with optimized set method needs to consider the characteristics of the mixed traffic flow as much as possible to reduce the mutual interference between pedestrians, non-motor vehicles and motor vehicle at the intersection of time and space resources. Run different types of traffic flow is one of the research-based methods to optimize timing as the intersection of time and space resources. Mixed traffic flow premise, give full consideration to the operating characteristics of the different types of traffic flow, different intersections motor vehicle imports lane, the exit lane, the gradient lane set; intersecting road grade, non-motor vehicle imports Road set Methods; arrangements combined with the phase sequence, and the intersection of the time idle resources, a pedestrian waiting area; consider the specific circumstances of the circular intersection traffic distribution, cross-sectional opening is provided according to the needs of the center island, through the phase signal light control and cross-sectional mouth The combination of traffic volume straight traffic fast channel, set on the basis of some diversion facilities and pedestrian crossing facilities, and to improve the use of the spare area of ??the intersection safety of pedestrians and non-motorized intersection; waiting area, set a left turn to shorten turn left at the distance of the vehicle through the intersection, more rational use of space resources. On this basis, according to the the intersection traffic characteristics of our plane, respectively, to study the applicability of the different phase combinations; combine different intersections, the proposed method of determining the phase sequence; combine existing research abroad and domestic The traffic flow distribution of the specific characteristics of the proposed optimization algorithm. User perspective, the proposed level of service evaluation system and operational efficiency and safety guidelines to select different indicators on last use of analytic hierarchy process evaluation results. Finally, through practical examples, the use of the methods mentioned in the text of its optimized design, and through service level optimization of instance, reflect the intersection of time and space resources to optimize the configuration of practicality.
