基于城市主要道路交叉口实际情况的调查,该论文结合了工程理论知识和方法,通过工作抽样和秒表计时的方法,该论文收集了道路交叉口的基本数据跟信息,然后通过排队论中M/D/1的模型来确定车辆的平均等待时间,接着从设备布置跟人员安排的角度来实现道路的全面提高。通过采用AHP(根据某些目标)来实现采用方案的选择跟评价。结果表明,对道路交叉口的既有方案的分析跟优化能有效地降低交通压力,以及在保证交通安全的前提下提高道路通行能力。
Based on the investigation of the actual situation of urban road junctions, the paper combines engineering theory knowledge and method, through working sampling and time-keeping of stopwatch. The paper collects the basic data and information of road intersections, D / 1 model to determine the average waiting time of the vehicle, and then from the perspective of equipment layout and staffing to achieve an overall improvement of the road. Through the use of AHP (based on some goals) to achieve the use of options and evaluation. The results show that the analysis and optimization of existing solutions at road intersections can effectively reduce the traffic pressure and enhance the traffic capacity of the road under the premise of ensuring traffic safety.
