摘　　要：传统的车辆出行调查人力、物力成本较高,且难以模拟得到车辆的出行轨迹.运用交通信息采集和处理技术,基于脱敏处理的车辆牌照数据推断出车辆出行的大致起讫点(OD),然后通过高德地图API接口调用路线导肮功能进行车辆出行轨迹的模拟,在出行时间最短的原则下确定实际的出行路线、出行时耗及出行距离等数据.根据上述方法对青岛市居民出行特征进行分析,研究结果表明:人口和岗位沿海分布密集,并向内陆延伸,体现了产业外溢的趋势;线路非直线系数与出行起讫点密切相关,出行起讫点直线距离越远,线路非直线系数越小,受环湾发展的影响,全市驾车出行的非直线系数偏高(1.42);驾车出行的距离高于相关规范要求,相反出行时耗低于相关规范要求.It is difficult to simulate the vehicle's travelling trajectory by the traditional vehicle trip survey for its high cost of manpower and material resources.Using the traffic information collection and processing technology,the origin and destination(OD)of vehicle trip is deduced based on vehicle license plate recognition data.Then,the vehicle travelling trajectory is simulated with the route navigation function of API(Application Programming Interface).Finally,the actual travel routes,travel time and travel distance are determined based on the principle of the shortest travel time in one trip.Based on the above method,the travel characteristics of vehicles in Qingdao are analyzed.The results show that:the population and posts are densely distributed in the coastal area and continually extend toward inland,reflecting the trend of industrial spillover;the non-linear coefficient of the path is closely related to the origin and destination of one trip.The farther the straight distance is,the smaller the non-linear coefficient is.Affected by the development of the Ring Bay,the non-linear coefficient of driving in Qingdao City is high(1.42);the distance of driving is higher than the requirement of relevant norms,while the travel time consumption is lower.
