Since the travel route of the bus is relatively fixed, the current location can be determined through communication with the base station and the station terminal. Therefore, the bus may not be equipped with a satellite positioning module; and the taxi is not equipped with a fixed travel route. It may even leave the city, so its positioning module mainly uses a satellite positioning module (such as GPS or Beidou); the third Zigbee communication module is used to realize communication with the Zigbee communication module of the base station or smart station terminal; the Gprs module is used as a backup communication module, once the third Zigbee communication module cannot communicate with the base station or the intelligent stop sign terminal, then start the Gprs module to directly communicate with the intelligent traffic management service center to ensure that the vehicle can maintain smooth communication with the intelligent traffic management service center anytime and anywhere; display module It is used to display the current running status of the vehicle and the instructions received from the management service center; the power supply module is used to provide the necessary working power for each module of the vehicle terminal.
手持终端可以为平板电脑、PDA、智能手机等设备，手持终端要求能通过wifi或者 Grps连接到internet。通过在手持终端5上安装客户端查询软件，即可连接到智能交通管理服务中心。用户启动客户端查询软件后，可直接查询某站台某线路公交车（如A站台1路车）下一班次到达时间，也可根据出发地和目的地查询出行建议。当根据出发地和目的地进行查询时，如果手持终端有定位功能，则可自动定位当前所在地为出发地，也可输入或选择出发地，再输入或选择目的地；如没有定位功能，则需输入或选择出发地目的地和目的地。智能交通管理服务中心接收该查询条件后，根据当前路况、车况等信息通过优化分析给出最佳出行方案并发送回客户端，如最近的公交站台、可乘坐的公交线路下一班车到达时间，预计到达目的地时间；附近出租车联系方式、等候位置，以及乘坐出租车出行线路建议和估计行程时间等信息。The handheld terminal can be a tablet computer, PDA, smart phone and other devices, and the handheld terminal is required to be able to connect to the internet through wifi or Grps. By installing the client query software on the handheld terminal 5, it can be connected to the intelligent traffic management service center. After the user starts the client query software, he can directly query the arrival time of the next bus on a certain platform (such as No. 1 bus at platform A), and can also query travel suggestions according to the departure place and destination. When querying based on the departure place and destination, if the handheld terminal has a positioning function, it can automatically locate the current location as the departure place, or input or select the departure place, and then input or select the destination; if there is no positioning function, you need to Enter or select Origin Destination and Destination. After receiving the query conditions, the intelligent traffic management service center will give the best travel plan through optimization analysis according to the current road conditions, vehicle conditions and other information and send it back to the client, such as the nearest bus stop, the arrival time of the next bus on the available bus line, Estimated time of arrival at the destination; nearby taxi contact information, waiting location, and information such as taxi travel route suggestions and estimated travel time.
此外，如果用户需要提前了解出行方式，则查询时可增加期望到达时间或预计出行时间作为查询条件，系统根据所要求时间段的历史路况信息和车况信息通过优化分析提供最佳出行建议，比如可乘坐公交车车次、或者建议乘坐出租车，如果发现所查时间的可能交通拥挤、路况较差，则提醒用户尽早出行，并提供可乘坐公交车车次等信息。In addition, if the user needs to know the travel mode in advance, the expected arrival time or estimated travel time can be added as the query condition when querying. The system provides the best travel suggestions through optimization analysis based on the historical road condition information and vehicle condition information of the required time period. For example, Take the bus number, or suggest taking a taxi. If it is found that there may be heavy traffic and poor road conditions at the time checked, the user will be reminded to travel as soon as possible, and information such as the bus number that can be taken will be provided.
以上所述仅是本发明的优选实施方式，应当指出：对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements and modifications can also be made, and these improvements and modifications are also possible.
