【摘要】：根据系统分析的方法,建立了交通状态与拥挤程度评价指标体系。根据路网交通拥挤率和路网交通拥挤促成度2个指标,评价了交通拥挤的影响程度,确定了交通合理性的判断标准,建立了城市用地再开发下交通拥挤预检方法,以马里兰州部分地区的无再开发、住宅再开发、住宅与就业再开发3种方案为例进行实例验证。分析结果表明:在第1种方案下,小汽车分担比、平均出行距离、总行驶里程、总行驶时间、总车辆延误、拥挤车道里程、车辆延误指数和拥挤车道里程比分别为93.70%、24.98km、225 817 698km、5 369 291h、2 038 880h、4 686km、0.380、0.180;在第2种方案下,上述指标分别为92.48%、24.78km、219 992 101veh、5 227 303h、1 831 190h、4 320km、0.350、0.166;在第3种方案下,上述指标分别为92.22%、24.82km、219 023 166km、5 342 457h、2 062 041h、4 422km、0.386、0.169;3种方案的路网交通拥挤度分别为0.280、0.258、0.278,但第3种方案下的车辆延误和车辆延误指数增加,第2种方案对交通拥挤具有轻微缓解作用,优于其他2种方案。
[Abstract]:According to the method of systematic analysis, the evaluation index system of traffic state and congestion degree is established. According to the two indexes of road network traffic congestion rate and traffic congestion contribution degree, this paper evaluates the influence degree of traffic congestion, determines the judging standard of traffic rationality, and establishes the pre-check method of traffic congestion under the redevelopment of urban land. Three schemes of no redevelopment, residential and employment redevelopment in parts of Maryland are taken as an example. The results show that under the first scheme, the car sharing ratio, the average travel distance, the total mileage, the total driving time, the total vehicle delay, the crowded lane mileage, The vehicle delay index and the mileage ratio of congested lanes are 93.70 respectively. The vehicle delay index and the mileage ratio of congested lanes are 24.98 km / 225,817 698km / 2 038 / 291h / 2 038 880km / 4686km / 0.180 respectively; under the second scheme, the above indicators are 92.48km219 992 101veh5 227 303h / 1 831 190h / 4 320km/ 0.166; under the third scheme, The above indicators are 92.22mg 24.82km / g 219,023 166km / h / 5 342,457hu / 2 062 041h / 4 422km/ 0.386km/ 0.169.The traffic congestion degree of the three schemes are 0.280 / 0.258km/ 0.278, respectively. However, under the third scheme, the vehicle delay and the vehicle delay index increase, and the second scheme has a slight effect on alleviating the traffic congestion. It is superior to the other two schemes.
