以及，无线车载终端将定位请求发送至上述至少两个不同的定位接口，以触发每个定位接口分别将接收到的定位请求发送给各自对应的定位服务器；以及，获取至少一个定位接口对应的定位服务器发送的位置信息，并获取从第一时刻到第二时刻的响应时间，第一时刻为每个定位接口发送定位请求的时刻，第二时刻为每个定位接口接收到位置信息的时刻；
以及，无线车载终端将与每个定位接口对应的响应时间与响应阈值进行比较，并从响应时间未超过响应阈值的定位接口所接收的位置信息中提取定位精度最高的位置信息作为车辆的即时位置。
本发明实施例中，实施上述实施方式可以精确的获取车辆的即时位置，提高定位精确度。
303、信息发布平台根据每一车辆的即时位置与该高层建筑的位置之间的直线距离，判断是否存在与该高层建筑的位置之间的直线距离小于指定阈值的目标车辆，如果存在，执行步骤304；如果不存在，结束本流程。

309、信息发布平台接收目标车辆上报的临时停车位置，并从监控到的所有车辆中筛选出处于行驶状态的车辆构成第一车辆集合，从第一车辆集合中筛选出在该临时停车位置所在道路上并且朝该临时停车位置方向行驶的行驶车辆构成第二车辆集合。
310、信息发布平台计算该临时停车位置与第二车辆集合中每一行驶车辆的即时位置之间的即时距离，并向第二车辆集合中每一行驶车辆发送公告信息，该公告信息包括临时停车位置与行驶车辆的即时位置之间的即时距离和目标车辆的车辆标识。
其中，实施步骤308～步骤310，可以使在该临时停车位置所在道路上并且朝该临时停车位置方向行驶的行驶车辆的驾驶员及时了解在该道路上的某一距离处有车辆临时停车，从而可以提前减缓车速，以防发生交通事故。
