Reporter Liu Huan Liu Mian
This year, 100 bus lines operated live via mobile phone "live". Passengers simply enter a station name on the phone, are available for the fastest when the bus arrives. Yesterday, the Beijing Municipal traffic information data analysis window of Minister Yu Haitao and visit the capital, disclosed, Tongzhou district and yanqing County lines within this year will achieve full coverage is expected by 2015 all bus lines in the city will realize that convenience queries.
Bus real-time queries to the accuracy rate will exceed 85%, operational data updates every 30 seconds, "delay" will not take more than 1 minute. At the same time, municipal public transportation group is seeking funding, hopes that by introducing a social investment, promote construction of electronic bus stop Board in the third ring, notice of bus arrival information.
100,000 visitors a week checking bus facts
Last month, on 14th, 2013 Beijing International Seminar on traffic information service, IOS, Android based smart phone terminal software "Beijing bus in real time" was first published, the first 78 model bus lines stop query service started.
"At present, 78 model wiring high views, just last week, more than 100,000 visitors. "Yu Haitao said the software in addition to viewing the bus live also has a query bus, bus transfer, collection of information sites, and feedback functions.
According to the plan, "Beijing bus in real time" in the beginning of the end of 2014, 2015 covers all bus lines in the city, involving some 900 lines.
Accuracy rate of over 85% up
In fact, buses with onboard satellite positioning systems far more than 100. Only public transport group, since 1998 have been in more than 12,000 vehicles have this equipment installed in buses.
Aeronautics and Astronautics research and testing of intelligent transportation Huang Jian, Deputy Chief Engineer of the Centre explained, "Beijing bus in real time" provide accurate rate of 85% bus stop information service, contrarily most errors in less than a minute. "No better not. ”
Bus group information services, Minister Liu Songyan Helsinki, plans to add more by 2015 nearly 8,000 car satellite navigation equipment, the original bus vehicle equipment to upgrade, to achieve full and more than 20,000 bus sequence monitoring and automatic station identification, while achieving a bus card automatic charging control and real-time capture and transmission of business data. "Won't have to wait after the completion of all the work together to launch real-time queries, matures one comes out with lines. ”
Mega database integrated to calculate time
Live "bus live", the transport sector has established a giant database. Access 22 operational system, contains a ground bus in the city over more than 900 lines of real-time GPS data base data, more than 10,000 vehicles buses, more than 60,000 cars taxi business information and credit card information such as credit card data in real time.
"We will collect GPS location data on the bus knew its exact location by taxis and other vehicles in the vicinity of the operating speed, comprehensive search figure out the runtime speed of the bus network, presumably after time reaches the next station. At the same time, traffic lights, acute congestion, also taking into account the context. Integrated calculate bus arrival time. "Huang Jian said that road conditions are constantly changing, so arriving in real time calculation will be refreshed every 30 seconds.
If bus lines have fine tuning will also change in the system in a timely manner. At present, the Software Development Department and bus group intricately drilled long public transit has developed a protection programme, like the line adjustment, the adjustment of the site, will be the first time to exchange information. "Passenger travel, avoiding detours. ”
Future reservation parking
Next, this "live" content will be more extensive. Such as the current Wi-Fi system on the bus, not only Internet access, bus passengers can also query information, track information, and make a change to the query, and so on. Vehicles stop real-time prediction services will also be provided in the future.
Liu Songyan revealed that in terms of electronic bus stop Board building, city bus groups by introducing a social investment approach to building, "coverage is within the third ring road, Changan Street, Avenue main street focus priority construction of Guangdong and Guangxi. ”
In addition, the transport sector will consider introducing public rental bikes and parking information, start the key technologies of integrated public transport travel information service-oriented research and development. People using a mobile phone can see the load factor of the parking lot, you can even reserve spaces.

今年年内，100条公交线路的运营实况将通过手机“直播”。乘客只需在手机上输入一个站名，就可查询到最快一班公交车何时抵达。昨日，北京市交通信息数据分析部部长于海涛在做客首都之窗时透露，今年内通州区和延庆县的线路将实现全覆盖，预计到2015年本市所有公交线路都将实现这种便民查询。
公交实时查询的准确率将超过85%，运营数据平均每30秒更新一次，“误点”时间不会超过1分钟。同时，市公交集团正在争取资金，希望通过引入社会化投资等方式，在三环内推广建设电子站牌，预告公交车到站的情况。
一周10万人次查公交实况
上个月14日，2013北京交通信息服务国际研讨会上，基于IOS、Android智能手机的终端软件“北京实时公交”首次发布，首批78条示范公交线路开始提供实时到站查询服务。
“目前，78条示范线路浏览量居高，仅上周就超过了10万人次。”于海涛透露，这款软件除了查看公交实况，还具有查询公交信息、公交换乘、收藏站点和意见反馈等功能。
按照规划，“北京实时公交”将于2014年底2015年初覆盖本市所有公交线路，涉及大约900条线路。
准确率超85%才可上线
其实，拥有车载卫星定位系统的公交线路远比100条多。仅公交集团，1998年至今已经在12000余辆公交车上安装了这套设备。
北京航空航天大学智能交通研究试验中心副总工程师黄坚解释，“北京实时公交”提供公交到站信息服务的准确率达85％，到站时间大部分误差都会在一分钟之内。“不准不如不报。”
公交集团信息中心信息服务部部长刘松岩介绍，计划2015年以前再新增近8000套车载卫星定位设备，对原有公交车辆车载设备进行软件升级，实现全部两万余辆公交车辆的位置监控和自动站序识别，同时实现自动计费控制和公交卡业务数据实时采集传输。“不会等全部工作完成之后一块儿推出实时查询，成熟一条就会推出一条线路。”
巨型数据库综合算出时间
直播“公交实况”，交通部门专门建立了一个巨型数据库。其中接入了22个业务系统，包含了全市地面公交900余条线路的基础数据、1万余辆公交车的实时GPS数据、6万多辆出租车实时运营信息和一卡通刷卡数据信息等。
“我们将通过采集公交车上的GPS定位数据知道它的具体位置，通过出租车等附近车辆的运营速度等，综合计算出公交线网的实时运行速度，之后推测到达下一站的时间。同时，红绿灯、突发拥堵等也在考虑范畴。这样综合算出公交到站时间。”黄坚说，由于路况是不断变化的，因此实时到站的计算每30秒会刷新一次。
如果公交线路有微调，也将及时在系统内变更。目前，该软件研发部门与公交集团和祥龙公交制订了一个保障方案，像线路的调整、站点的调整，会第一时间互通信息。“保证乘客出行，避免走弯路。”
未来可预约停车场车位
未来，这种“直播”的内容将更广泛。比如目前公交车上的无线上网系统，不但可以上网，乘客还可查询公交新闻、线路信息，并进行换乘查询等操作。未来还将提供车辆到站实时预报服务。
刘松岩透露，在电子站牌的建设方面，市公交集团将通过引入社会化投资的方式来建设，“覆盖范围是三环内，长安街、两广大街等重点大街优先建设。”
另外，交通部门将考虑引入公共租赁自行车和停车场信息，启动面向公共交通一体化出行的信息服务关键技术的研发。市民用手机就能看到停车场的满载率，甚至可以预约车位。
