Description

基于电子地图的交通和旅行信息服务系统及方法 技术领域
本发明涉及智能交通技术领域，尤其涉及一种基于电子地图的交通和旅行信息服务系统及管理方法。
背景技术
任何旅行需要实现从起始地到目的地之间的交通，都必须借助畅通、安全的交通条件。旅行和交通不可分割，畅通安全的交通是愉悦旅行的首要条件，而旅行的目的不仅仅是为了满足出发地到目的地之间的交通，吃住差游是终极目标。随着我国旅游活动从低级的以赶景点为主要目标的“苦行游”，向包含文化内涵的以休假与游览结合为主的“休闲游”等方向的转化，交通和旅行信息服务至关重要。
道路交通，尤其是小康一族的上下班和自驾游是当前出行的主要交通方式，交通拥堵和安全事故频发已成为现今急需解决的难题。为缓解道路交通压力，实施摇号上牌、号牌限行(包括尾号、颜色和外地号牌)和高峰时段禁行；设置专用车道(公交专用车道、拼车专用车道等)、快速车道、潮汐车道、可变车道、导向信号灯以及收费路段等方式已经成为交通管理普遍的实践。对使用道路附加多种限制条件部分解决了交通拥堵和安全问题的同时，也为人们出行带来不便。
随着移动互联网的发展，驾车出行依靠电子地图进行定位和导航已经不是唯一目的，根据需要搜索和预约兴趣点，了解道路交通路况，避开拥堵和收费路段进行出行规划，已经越来越受到人们的欢迎。然而利用现有电子地图进行导航，在规划出行路线时仅能根据起始地到目的地的即时导航路径、当前路况、限速标志和超速提示，少有考虑道路交通运营管理中的种种限制、计划出行以及计划路况对出行的影响。当用户到达对应地点根据禁令标志获知前方道路限行无法通过，或毫无任何信息且前方拥堵时，已经给用户的出行带来极大的不便和困扰。
当道路发生突发事件导致交通事故或拥堵时，虽然现有电子地图具有报告交通事故、施工等交通事件的功能，但需要通过上报和审核的过程，且只有电子地图的制造商才能将事件信息显示在电子地图上，此类报告不仅不能避免追尾等恶性交通事件的发生和发展，所示警告信息在时间上的延误可能已经造成绵延数千米的拥堵；现有电子地图的路况更多地依赖导航中车辆的行驶速度来预测路段拥堵的状况，往往只能在发生该路段拥堵时才能提供信息，无法提供计划导航路径和计划出行拥堵预测数据；虽然根据历史通行数据可以部分预测交通路况，几乎没有电子地图可提供计划路况信息，从而对出行造成不便。
现有专利文献如下：
道路交通路径诱导方法、系统及道路交通信息服务平台(CN106327899A)中告知：通过对路径规划导航路径中的所有路段执行预约，从而实现道路交通的预测和管理。该专利是理想状态下对出行的道路交通路径进行全时段和全路段预约，工作量大、实施难度高且很多情况下没有必要。
一种移动通信终端及交通监测设备探测方法(CN105280001A)中告知：设置路况汇报开关，当用户驾车时发现前方有事故或路况信息时，通过按下路况汇报开关即可启动汇报流程，预处理单元将信息采集单元采集的数据通过无线网络发送给主控单元。主控单元则可以取得当前汇报车辆的位置信息、车主汇报音频信息、一段时间内汇报车辆周围的视频信息和当前车周围图片信息。该方法所告知汇报流程所经历的时间长，不适用于紧急情况下事故或路况信息的发布，且该专利仅提出对事故或路况信息采集和上传，离开了人们普遍依赖的电子地图，因而无法通过更新路径规划和导航来提供交通诱导服务。
基于云系统的交通信息管理与服务系统(CN104376494B)中告知：可以根据用户需求，对交通事件进行分类、分级管理，然后每一类交通事件监测信息按照交通事件影响程度进行逐级设定，如涉及到某一类交通事件需要双向断路、单向断路、封闭一条车道、封闭两条车道等，来设定交通事件的等级。该专利虽然能综合多种交通限制条件对交通进行管理，但其对交通的管理将影响所有车主，即，仅能实现交通日常管理、应急处置，未考虑现今复杂多变的交通状况；同时，该专利并未将交通事件监测信息通过电子地图为用户提供诱导服务。
即使将现有公知和上述现有专利基于交通和旅行信息实现的服务组合在一起并不全面，不适用于现今复杂多变的交通情况，无法针对个人即时/计划的出行需求提供适用的交通和旅行信息和服务，如高速公路上无论小客车、商用客车或货车，为用户提供最高限速120千米/小时的超速报警；无法同时满足与用户旅 行相关的需求并提供安全保障，如对接第三方平台提供紧急求助服务、紧急事件时的安全；更无法为管理者提供便捷有效的管理手段，如将交通路况路径及预告结果映射到路侧单元，路侧单元信息的编辑如交通信号灯的周期及通行方向，调整热门兴趣点信息(如景区或公共交通场站)的地理位置等来改变路径规划和导航以及违法信息的采集和查处等。
综上，现今需要对现有技术进行改进。

删除：将对象及其属性、相关的管理与服务从动态地图112相应的图层上去除；
注：对多个对象进行新增、编辑、拷贝和/或删除的操作时，可以先在管理终端上进行操作，然后统一通过通信中心12上传至云计算中心10进行浏览和出版。
浏览：即，管理终端4将所输入更新信息(至少一条)和浏览请求通过通信中心12上传至云计算中心10。云计算中心10接收、记录、储存和分析处理所接收上述信息，并根据该信息向对应图层进行相应操作，最后将云计算中心10将生成动态地图112通过通信中心12发送至对应管理终端2，由管理终端2 进行显示，用于检查对象的地理位置坐标或范围、属性及其管理与服务的信息；
出版：即，管理终端4将输入更新信息(至少一条)和出版请求通过通信中心12上传至云计算中心10。云计算中心10接收、记录、储存和分析处理所接收上述信息，并根据该信息向对应图层进行相应操作，最后将云计算中心10更新后的动态地图112进行反馈(即，通过通信中心12发送至对应管理终端2)和出版(当管理终端2和用户终端4通过通信中心12调用该动态地图112时，云计算中心10通过通信中心12将其同步更新至对应管理终端2及用户终端4，还通过通信中心12将其同步更新至对应管理路侧单元)；
注：通过浏览确认的动态地图112出版后，各管理终端2及用户终端4可以浏览和使用。
管理终端2包括交通运营管理终端、兴趣点运营管理终端和交通执法终端，交通运营管理终端、兴趣点运营管理终端和交通执法终端均与通信中心12信号相连。
交通运营管理终端用于根据城市交通和道路交通的规范，通过通信中心12向云计算中心10对兴趣点信息、路侧单元信息和路径信息提出管理终端请求。
即，交通运营管理终端用于提出管理与服务为道路交通营运管理的管理终端请求，从而满足交通营运管理的要求；
云计算中心10通过通信中心12接收该交通营运管理终端发送的管理终端请求，根据更新信息中的对象(保存在相应图层的路侧单元信息、路径信息、兴趣点信息)进行相应操作(新增、编辑、拷贝和/或删除)，最后云计算中心10将根据浏览请求通过通信中心将更新后的路侧单元信息、路径信息或兴趣点信息反馈给对应管理终端2，还根据出版请求将更新后的路侧单元信息、路径信息或兴趣点信息进行出版，即，当管理终端2和用户终端4通过通信中心12调用该动态地图112时，云计算中心10通过通信中心12将其同步更新至对应管理终端2及用户终端4，同时云计算中心10还根据管理终端请求通过通信中心12将其发送至管理路侧单元31。
交通运营管理终端主要对交通安全和效率相关的路侧单元信息和路径信息进行管理，如对交通标志、信号灯、可变信息牌，预约车道、快速车道、专用车道、互通立交、隧道、高架、桥梁和汽车轮渡等信息进行管理，而兴趣点信息仅仅作为一般信息的管理而存在如收费站、休息处和旅游景点。
如：根据交通部门对道路的设计，对该道路的路侧单元信息和路径信息进行设置，操作为新增；当该道路投入使用且兴趣点信息、路侧单元信息和路径信息发生变化时，交通运营管理终端向交通系统中心1提出管理终端请求，对路侧单元信息、路径信息和兴趣点信息进行修改，操作为编辑、拷贝或删除。
由上可知交通运营管理终端对动态地图112的管理终端请求，与在现场道路设置路侧单元、施划车道完全一样。区别在于现场的路侧单元、标志和标线全时段适用于所有路过的车辆和用户，需要用户结合自身的情况和时间段进行辨别；而电子地图的路侧单元信息和路径信息，根据时间属性和非时间属性，结合车辆信息的车型、车辆种类和许可证以及时间段，仅仅适用于匹配一致的车辆，无需用户辨别即可准确传递信息。
与传统电子地图比较，本发明中交通运营管理终端对车道和出口预告标志的精益化管理，如2千米、1千米，500米出口预告标志信息和出口预告(行动点)标志信息，不再适用所有车辆而仅仅对导航路径为离开出口的车辆。导航过程中车辆接近岔路口，且导航路径为直行时，交通系统中心1不向该车辆提供任何出口预告；导航路径为离开出口时，交通系统中心1才向这些车辆提供相应的出口预告；从安全角度考虑，岔路口保持直行的指路信息不再是多个车道的直行提示，而是保持某个当前车道的直行提示(如图6所示)。
交通运营管理终端包括信号相连的交通运营管理PC终端(用于监察)和交通运营管理移动终端(用于巡查)；交通运营管理PC终端和交通运营管理移动终端均与通信中心12信号相连；交通运营管理PC终端和交通运营管理移动终端均具备上述交通运营管理终端的全部功能，故不在此处进行重复表述。
兴趣点运营管理终端用于通过通信中心12向云计算中心10提出管理终端请求，进行对兴趣点营运和管理。
即，兴趣点营运管理终端用于提出管理与服务为兴趣点营运管理的管理终端请求，从而满足兴趣点营运管理的要求；
云计算中心10通过通信中心12接收该兴趣点营运管理终端发送的管理终端请求，根据管理终端请求对象(路侧单元信息、路径信息、兴趣点信息)进行相应操作(新增、编辑、拷贝和/或删除)，最后云计算中心10将根据浏览请求通过通信中心12将更新后的路侧单元信息、路径信息或兴趣点信息反馈给对应管理终端2，还根据出版请求将更新后的路侧单元信息、路径信息或兴趣点信息进行出版。
如对停车场、车站和码头、旅游景点、酒店、娱乐和美食等兴趣点信息，进行包括价格、服务、预约、评价等营运及管理。当兴趣点信息的管理达到足够精益的程度时，如停车场的泊位平面图、通道和出入口信息，购物中心的楼层、电梯、商店、餐饮、卫生间信息，可能涉及路侧单元信息、路径信息和进一步的兴趣点信息。
与传统电子地图比较，基于本发明兴趣点运营管理终端对兴趣点信息的精益化管理，兴趣点信息在电子地图上的地理位置不再是一个区域和一个或多个出入口，更多地赋予了楼层平面图、室内平面图、内部兴趣点信息等便于定位和导航的信息；当兴趣点周边的交通压力严重影响交通拥堵和旅行体验时，通过兴趣点运营管理终端请求，通向兴趣点的车流可能被导向周边的换乘中心、停车场或途径通道，从而限制通向兴趣点出入口的车流。
兴趣点营运管理终端包括信号相连的兴趣点营运管理PC终端(用于监察)和兴趣点营运管理移动终端(用于巡查)；兴趣点营运管理PC终端和兴趣点营运管理移动终端均与通信中心12信号相连；兴趣点营运管理PC终端和兴趣点营运管理移动终端均具备上述兴趣点营运管理终端的全部功能，故不在此处进行重复表述。
交通执法管理终端用于根据交通事件，通过通信中心12向云计算中心10提出管理终端请求。
即，交通执法终端用于提出管理与服务为交通事件应急管理的管理终端请求或用户终端4，从而满足交通事件应急管理要求或进行交通诱导服务；
云计算中心10通过通信中心12接收交通执法终端发送的管理终端请求，根据管理终端请求对象(路侧单元信息、路径信息、兴趣点信息)进行相应操作(新增、编辑、拷贝或删除)，最后云计算中心10将根据浏览请求通过通信中心将更新后的路侧单元信息、路径信息或兴趣点信息反馈给对应管理终端2，还根据出版请求将更新后的路侧单元信息、路径信息或兴趣点信息进行出版。
当管理与服务为交通事件应急管理时：
在发生交通事故时，通过交通执法终端增设事故标志的路侧单元信息(新增路侧单元信息)，从而使云计算中心10将该路侧单元信息新增在对应路径路侧单元图层上，对动态地图112进行更新；
还可按照实际需要，通过交通执法终端按照上述方法对路侧单元信息和路径信息进行相应操作，如关闭事故路段的一个车道并调整事故路段的接纳容量及速度(编辑路径信息)，在通向事故路段的路口放置改道或禁止驶入标志(新增路侧单元信息)等，云计算中心10根据管理终端请求对动态地图112进行更新，
云计算中心10将更新后的动态地图112，根据管理终端2及用户终端4的调用将其通过通信中心12同步至对应管理终端2及用户终端4，驾驶员可通过用户终端4提前获知路况，从而及时调整出行计划。
针对交通事件的性质，交通执法终端提出管理终端请求时，其管理与服务通常包含有效期的属性，即交通执法终端对路侧单元信息和路径信息的管理终端请求为处理交通事件所进行的临时变更。即，上述针对交通事件设置的路侧单元信息、路径信息、兴趣点信息及其属性，在规定的时间后自动从电子地图上清除，或由管理终端2人工清除。
当管理与服务为交通诱导服务时具体案例如下：
交通执法管理终端通过可变信息告示牌和交通信号灯等管理路侧单元31的路侧单元信息进行操作，从而实现交通诱导服务，具体方法如下：
应对交通事件如交通事故、交通拥堵、恶劣天气、道路施工、计划活动、早晚高峰，交通执法人员通过交通执法终端输入管理终端请求，包括应急设置路侧单元信息如交通信号灯、可变信息指示牌及可变信息告示牌的变化周期和显示内容，应急设置路径信息如潮汐车道、可变车道的通行方向及相应的路侧单元信息，应急开启或关闭通道或出入口以及出发区、到达区、等待区的车道的路径信息，应急使用换乘停车场的兴趣点信息等；交通执法管理终端将上述信息发送至通信中心12；通信中心12接收并将其转发至云 计算中心10，云计算中心10接收、记录、储存和分析处理所接收管理终端请求，并根据管理终端请求更新电子地图中心11对应的电子地图路侧单元信息、路径信息及兴趣点信息，云计算中心10将更新结果通过通信中心12反馈交通执法管理终端，并将更新后动态地图112同步至调用其的管理终端2和用户终端4。
云计算中心10还根据实际需要将更新后路侧单元信息，根据管理终端请求通过通信中心12发送至对应管理路侧单元31，令管理路侧单元31按照更新后的路侧单元信息进行相应工作；
如：路侧单元信息的编辑为交通信号灯周期及持续时间的调整：通过云计算中心10的处理和同步后，实际的交通信号灯将按更新后的交通信号灯周期及持续时间进行工作，在其导航工作中，根据其位置和移动方向，用户终端4向用户即时显示更新后交通信号灯的状态及状态变化剩余时间(如距离将通过的交通信号灯500m处开始显示)，令用户通过用户终端4获知前方红绿灯的具体状态及读秒情况，从而有助于用户控制合理的行驶速度，避免交叉路口的冲刺或紧急刹车。
路侧单元信息的编辑为调整潮汐车道和可变车道通行方向对应的指路标志等；通过云计算中心10的处理和同步后，实际的指路标志按更新后方向进行指示，用户终端4为用户显示对应路段的电子地图时，也按照更新后方向进行显示。
云计算中心10还根据实际需要将更新后的路径信息和兴趣点信息同步至对应兴趣点和路径，令兴趣点/路径按照更新后的兴趣点/路径信息进行相应工作；
路径信息和兴趣点信息的编辑包括通向旅游景点的一个通道或出入口的开启或关闭，机场、车站或码头出发区、到达区或等待区的一个或多个车道的开启或关闭，将热门兴趣点信息(如景区或公共交通场站)指向一个换乘停车场的信息等；路径信息的操作尤其包括潮汐车道和可变车道通行方向的调整以便提供准确的路径规划和导航。
综上，云计算中心10根据交通执法终端的管理终端请求对可变信息指示牌和交通信号灯的路侧单元信息进行编辑，改变潮汐车道和可变车道的通行方向，开启或关闭通道或出入口以及出发区、到达区、等待区的车道等路径信息，并将上述更新通过通信中心12通过管理终端请求发送至对应管理路侧单元31；同时动态地图路径图层、兴趣点图层及其对应的路侧单元图层实现同步调整，并同步至调用其的管理终端2及用户终端4，从而返回给用户，实现交通诱导服务。
交通执法管理终端还可进行交通路况路径规划和预告，通过通信中心12向云计算中心10提出交通路况路径规划请求和映射请求，具体操作如下：
管理员通过交通执法终端输入交通路况路径规划请求信息(一个出发地、一个以上目的地及更新周期)，交通执法终端将上述信息及交通路况路径规划请求通过通信中心12发送至云计算中心10进行路径规划；
云计算中心10将根据交通路况路径规划请求信息，生成同一出发地面向多个目的地的交通路况路径以及预告结果，并将结果发送到对应交通执法终端反馈给管理员；
管理员根据交通路况路径以及预告结果利用交通执法终端通过通信中心12向云计算中心10发送映射请求和映射信息(包括指定管理路侧单元31的路侧单元信息)；云计算中心10将按照交通执法终端的映射请求，按照设定的更新周期将交通路况路径、预告结果通过通信中心12更新所指定的管理路侧单元31，如位于出发地的可变信息告示牌。
与传统电子地图比较，基于本发明交通执法终端对车道和出口预告标志的精益化管理，如2千米、1千米，500米出口预告标志和出口预告(行动点)标志，可对交通营运管理终端设置的出口预告规则进行改变，交通事件情况下如交通事故、恶劣天气或抢险施工等，车辆接近交叉口时，交通系统中心1一律向所有车辆提供出口预告和交通事件警告，而非仅仅针对导航路径为离开出口的车辆；
交通执法终端还用于获取车辆的违法信息、采集证据并查处(如图5所示)，如在禁止泊车和滞留的区域车辆滞留超过规定的时限，在禁止驶入的时段和路段范围内违法行驶，行驶速度超过规定的最大限速或平均时速，在交通信号灯禁止通行周期内通过路口等。
交通执法终端包括信号相连的交通执法PC终端和交通执法移动终端；交通执法PC终端和交通执法移动终端均与通信中心12信号相连；交通执法PC终端和交通执法移动终端均具备上述交通执法终端全部功能，故不在此处进行重复表述。
云计算中心10将其所生成的交通路况信息通过通信中心12发送至交通执法PC终端和交通执法移动终端，云计算中心10还将所获取交通事件监测信息通过通信中心12同步至交通执法PC终端，即，交通执法PC终端可查看各路侧单元、管理终端2和用户终端4上报的交通事件监测信息，实现对交通路况的实时监测。
云计算中心10信号还将车辆信息通过通信中心12同步至道路交通执法PC终端，即，交通执法PC终端可查看对应车辆的车辆号牌、车型和行车轨迹(即，对应车辆信息经云计算中心10分析处理后所得的车辆位置与时间关系地图)。
交通执法PC终端在出现拥堵路况和交通事件时，即时将对应交通事件监测信息转发最近的交通执法移动终端，提醒交通执法人员前往处理；即，交通执法PC终端用于进行违法记录，交通执法移动终端用于现场处理违法。
用户终端4至少包括一组信号相连的驾驶员终端和车载单元；
驾驶员终端和车载单元均与各第三方平台9信号相连。
驾驶员终端分别与通信中心12和管理路侧单元31信号相连。

各车载单元之间信号相连；
驾驶员终端和车载单元均用于通过通信中心12向云计算中心10提出用户终端请求，从而实现查看电子地图，路径规划、预览和目的地导航，兴趣点或路径的预约以及紧急求助等功能。
驾驶员终端和车载单元均用于进行交通事件报告；
驾驶员终端可通过管理路侧单元31向通信中心12发送交通事件报告，或直接向通信中心12发送交通事件监测信息；
车载单元可通过管理路侧单元31向通信中心12发送交通事件报告，或直接向通信中心12发送交通事件监测信息；还可以通过车车通信向短程信号范围内其他用户终端4(如前后车辆对应的用户终端4)发送交通事件监测信息；
注：管理终端请求和用户终端请求均为地图服务请求。
驾驶员终端还用于将其所显示的信息映射至对应车载单元，由车载单元显示驾驶员终端所映射的信息，为驾驶员提供熟悉的显示界面、更为安全的操作环境与舒适的驾驶体验；
车载单元还用于采集车辆前后方向的视频信息。随着科技的发展车载单元还可包括自动泊车、自动驾驶和应急处置(如驱动、制动、转向、信号和报警等)的特殊功能，除特别说明外，本说明书以驾驶员终端为例进行详细介绍。驾驶员终端和车载单元信号相连(如BLE，WiFi，MiliLink，CarPlay)，驾驶员终端(C2N)和车载单元(V2N)分别与通信中心12(或第三方平台9)信号相连，车载单元和管理路侧单元31之间信号相连(V2I)，车载单元和车载单元之间信号相连(V2V)。驾驶员终端和车载单元用于实时向通信中心12上传其位置信息，向周边车辆发送交通事件警告信息，向通信中心12上传交通事件监测信息和用户终端请求。
具体如下：
用户操作驾驶员终端或车载单元向通信中心12提出用户终端请求，通信中心12将其发送至云计算中心10；云计算中心10接收、记录、储存和分析处理所接收的用户终端请求，并将结果通过通信中心12发送至对应驾驶员终端或车载单元，由驾驶员终端或车载单元反馈给用户。

用户操作驾驶员终端，直接地(C2N)或通过管理路侧单元31间接地(C2I)向通信中心12上报交通事件监测信息，通信中心12将其发送至云计算中心10；云计算中心10接收、记录、储存和分析处理所接收的交通事件监测信息，并将结果通过通信中心12发送至适用的驾驶员终端、管理终端2和管理路侧单 元31，由驾驶员终端反馈给用户以警示和避让，由管理路侧单元31向更多的车辆进行告示，或由管理员终端及时处置并在清除交通事件后将其路侧单元信息从电子地图上删除。
用户终端请求包括查看电子地图、路径规划、目的地导航、路径和兴趣点预约和紧急求助。例如可参照以下情景：
3.1、用户终端请求为路径规划和目的地导航时：
用户终端4向交通系统中心1上传出发地、目的地和计划出行时间(请求信息)。云计算中心10接收用户终端请求后，根据请求信息中出发地和目的地，调取电子地图及路侧单元信息、路径信息和兴趣点信息。云计算中心10根据车辆信息分别与路侧单元信息、路径信息和兴趣点信息的非时间属性进行比较，根据属性匹配结果筛选能够畅通通行的导航路径。云计算中心10对畅通通行的路径进行路径规划，将规划所得路径按照旅行时间从低到高的顺序，依次将每条路径中各路侧单元信息、路径信息和兴趣点信息的时间属性与计划到达相关路侧单元(标识路侧单元和管理路侧单元31)、路径和兴趣点的时间进行比对，根据比对结果，结合车辆信息的许可证、车型等信息，筛选准许通行的导航路径，并将其反馈给用户。导航路径至少包括出发地、目的地之间的路段及其车道，路段到路段的路侧单元信息，里程以及预期旅行时间。
计划出行时间包括当前时间和计划时间，利用当前时间规划的路径为即时导航路径，利用计划时间规划的路径为计划导航路径。用户终端4接收导航路径并向交通系统中心1反馈，用户终端4根据用户终端4的位置和交通系统中心1接收的导航路径执行导航。
在导航过程中，用户终端4为用户显示车道级的电子地图，路段到路段的指路信息以及车辆前后方向的视频信息，并将交通系统中心下发的导航路径中各兴趣点信息(如收费站)、路侧单元信息(如禁止泊车和滞留)和路径信息(如预约路段)的属性，通过预设的规则与车辆信息和当前时间、地理位置进行对比，根据对比结果适时向用户播报适用的指路信息、指示信息、警告信息和禁令信息(如图3所示)；紧急情况下的警告信息，包括由周边车辆用户终端4发送的交通事件报告等警告信息。
预设的规则为针对兴趣点信息、路侧单元信息和路径信息中预设的报警和指示规则。
指路信息、指示信息、警告信息和禁令信息以图形词典形式通过用户终端4反馈用户，以便用户选用自己熟悉的图形、文字、语音、声光报警和触觉等形式来提供交通和旅行信息(如图4所示)。
3.2、用户终端请求为紧急求助：
包括紧急医疗救助、交通事故报警、车辆故障救援以及人身安全威胁状态救助；如果对应的用户终端请求为紧急医疗救助、车辆故障救援或人身安全威胁状态救助时，驾驶员终端和车载单元可与第三方平台9信号相连，以实现远程视频救助、位置共享和追踪。
用户终端4进行交通事件报告：
如车辆行驶导航过程中，出现交通事故，恶劣天气，紧急车辆、故障车辆、校车、信号灯违法车辆、异常转弯车辆或前方紧急制动车辆，行人或动物穿越，跌落物、障碍物或陷阱，通过施工区域等交通事件时，驾驶员通过操作驾驶员终端、或通过车载单元自动或手动启动交通事件报告。
驾驶员终端的功能可以映射到车载单元，使得用户可以在熟悉的驾驶员终端界面和更为安全的车载单元操作环境下实现功能，故此处以车载单元为例进行详细介绍：
通过车辆前后方向视频采集设备获取的交通事件，如前方紧急制动车辆、行人或动物穿越、跌落物、障碍物或陷阱，或前方校车、后方紧急车辆等，车载单元自动启动交通事件报告，通过车辆的显示器和报警器，为本车车辆提供图形、文字、声音和触感报警，提示驾驶员交通事件的性质及应急行动要求，如刹车、为紧急车辆让行等信息。
自动或手动启动的交通事件报告(发布交通事件监测信息)：利用车载单元的车车通信(V2V)向短程信号范围内其他车载单元发送交通事件监测信息，然后接收该交通事件监测信息的车载单元利用其显示器和报警器，驾驶员提供图形、文字、声音和触感报警，提示驾驶员交通事件的性质及应急行动要求，如施工区域、故障车辆、避让紧急车辆或紧急刹车。
自动或手动启动的交通事件报告(发布交通事件监测信息)：利用车载单元或驾驶员终端发送交通事件监测信息至通信中心12(通过管理路侧单元31发送至通信中心12)；通信中心12接收并将其转发至 云计算中心10；云计算中心10接收、记录、储存和分析处理交通事件监测信息；
云计算中心10针对上述各用户终端请求，分别进行以下处理：
交通事件上报请求：
云计算中心10根据车载单元或驾驶员终端发送的交通事件监测信息生成并更新交通路况信息，同时通过通信中心12将更新后的交通路况信息发送至对应管理路侧单元31)进行显示，和/或发送至相应的管理终端2和用户终端4。
云计算中心10还对交通事件监测信息进行分析处理，根据该交通事件监测信息判断是否更新电子地图中心11；判断需要更新，则根据交通事件监测信息更新电子地图中心11中对应图层，并将更新后的图层发送更远的用户终端4和适用的管理终端2，还可通过通信中心11由交通系统中心-基础设施通信(N2I)通知适用的管理路侧单元31(可变交通信息牌)显示交通事件及其地理位置，如230km处恶劣天气。交通事件报告按照一定的规则赋予时间属性，在规定的时间后自动从电子地图上清除，或由管理终端2人工删除。
即，云计算中心10接收用户终端4监测或采集的交通事件监测信息，并根据交通事件监测信息对电子地图相关路侧单元(如标志)信息进行操作，如在事故发生地添加交通事故标志，通过障碍物或陷阱路段添加警告标志，突遇恶劣天气时添加恶劣天气的警告标志等；当交通事件消除后，后续途径车辆可以进一步报告事件消除的信息，根据预设的处理规则将相应路侧单元信息从电子地图上删除。
传统电子地图的交通事件上报，需经地图制作商的审核和批准，由用户终端请求到地图制作商批准的过程可能已经造成绵延数千米的交通拥堵，更无法避免紧急状态下追尾事故的发生和发展。本发明交通事件的上报，通过车辆-车辆通信(V2V)可以瞬间通知周边的车辆传达危险和警告信息，避免紧急状态下事故的发生和发展；通过车辆-交通系统中心(V2N)，交通系统中心-车辆(N2V)以及交通系统中心-管理员终端(N2C)通信可以通知更远的适用车辆和适用管理员，以便及时改道和采取应急处置方案，通过交通系统中心-基础设施(N2I)通信和适用的管理路侧单元31(可变信息告示牌)，显示前方交通事件监测信息。
路径规划请求：
云计算中心10根据用户终端4的路径规划请求信息中的出发地、目的地和计划出行时间，调取电子地图路径图层、兴趣点图层的路径信息、兴趣点信息及其对应的路侧单元信息，将所得车辆信息与路侧单元信息、路径信息和兴趣点信息的非时间属性进行比对分析，根据属性匹配结果筛选能够畅通通行的导航路径；然后将所得导航路径按照旅行时间从低到高的顺序，依次将每条导航路径中各路径信息、兴趣点信息及其对应的路侧单元信息的时间属性与计划到达相关路径、兴趣点及其对应路侧单元的时间进行比对，根据比对结果，结合车辆信息的许可证、车型等信息，筛选准许通行的导航路径，并将其反馈给用户。
计划出行时间包括当前时间和计划时间，利用当前时间规划的路径为即时导航路径，利用计划时间规划的路径为计划导航路径。用户终端4接收导航路径并向交通系统中心1反馈，用户终端4根据用户终端4的位置和交通系统中心1接收的导航路径执行导航。
导航请求：
云计算中心10根据导航请求信息不断采集用户的地理位置、速度、方向角及可能的交通事件监测信息，根据地理位置、速度和时间更新交通路况信息，向用户终端4提供车道级的导航和路段到路段的指路信息，反馈更新的交通路况信息和其他任何适用的信息。

云计算中心10通过通信中心12接收紧急求助请求或预约请求时，根据紧急求助请求或预约请求对接第三方平台9，向第三方平台9发送对应的请求，接收、保存第三方平台9反馈的结果，并将该结果通过通信中心12和用户终端4反馈给用户。
查看电子地图请求：
利用用户终端4查看电子地图，包括路侧单元信息、兴趣点信息和路径信息的查看，为现有电子地图所有具备的一般功能，故不对查看电子地图请求的响应方式进行具体介绍。
本发明利用上述系统基于电子地图进行交通和旅行信息服务的方法，具体包括以下工作内容：
S1、交通系统中心1根据地图服务请求，为管理终端2和用户终端4提供交通和旅行信息服务的方法：
通过管理终端2或用户终端4输入地图服务请求，管理终端2或用户终端4将地图服务请求发送至交通系统中心1；交通系统中心1接收、记录、储存和分析处理所接收的地图服务请求并将处理结果发送至对应管理终端2或用户终端4，由管理终端2反馈给管理者或用户终端4反馈给用户。
S1.1、地图服务请求为管理终端请求：
管理终端2通过通信中心12将管理终端请求发送云计算中心10；
云计算中心10接收、记录、储存所接收的管理终端请求，并按照管理终端请求对电子地图中心11中路侧单元信息、路径信息或兴趣点信息进行相应操作，实现交通和旅行服务相关的道路交通营运管理、兴趣点营运管理、交通事件应急管理和交通诱导服务；
云计算中心10根据浏览请求通过通信中心12将更新后的路侧单元信息、路径信息或兴趣点信息反馈给对应管理终端2，还根据出版请求将更新后的路侧单元信息、路径信息或兴趣点信息通过通信中心12同步更新至调用其的管理终端2和用户终端4，根据管理终端请求通过通信中心12发送至对应管理路侧单元31。
具体包括以下情况：
对象为兴趣点信息、路侧单元信息和路径信息的管理终端请求的操作步骤相同，故此处以交通运营管理PC终端针对路侧单元信息提出管理终端请求为例，详细介绍交通运营PC管理终端向交通系统中心1发送管理终端请求的工作内容。
管理者通过交通运营管理PC终端输入管理终端请求(浏览请求/出版请求，以及至少一条更新信息)，交通运营管理PC终端将上述信息发送至通信中心12；通信中心12接收并将其转发至云计算中心10；云计算中心10接收、记录、储存和分析处理所接收管理终端请求；云计算中心10根据管理终端请求向电子地图中心11中保存在对应图层内的路侧单元信息、路径信息或兴趣点信息进行相应操作，从而实现道路交通运营的管理与服务。
云计算中心10分别根据管理终端请求于对应电子地图上新增、编辑、拷贝或删除对象，具体如下：
新增：云计算中心10根据对象于路径路侧单元图层或兴趣点路侧单元图层上增设一条路侧单元信息；
编辑：云计算中心10根据对象于路径路侧单元图层或兴趣点路侧单元图层中调取对应的路侧单元信息，将对象属性及其管理与服务进行修改。
拷贝：云计算中心10根据对象于路径路侧单元图层或兴趣点路侧单元图层中调取对应的路侧单元信息，再将其属性、相关的管理与服务完整地复制并摆放到动态地图112中其他地理位置相应的图层上便于快速编辑；
删除：云计算中心10根据对象于路径路侧单元图层或兴趣点路侧单元图层中调取对应的路侧单元信息，再将其属性、相关的管理与服务从动态地图相应的图层上去除；
云计算中心10根据管理终端请求中的浏览请求进行更新信息的确认，根据出版请求进行更新信息的发布；
浏览：云计算中心10按照管理终端请求中的更新信息生成对应的路径路侧单元图层或兴趣点路侧单元图层，并将其通过通讯中心12发送至对应交通运营管理PC终端，由交通运营管理PC终端向管理人员 显示更新后的电子地图，以供管理人员检查。
出版：云计算中心10按照管理终端请求中的更新信息更新对应的路径路侧单元图层或兴趣点路侧单元图层，并将其通过通讯中心12同步至对应交通运营管理PC终端(反馈)，根据管理终端请求将其发送至管理路侧单元31(同步调整其属性)，还根据用户终端4的调用通过通讯中心12进行同步更新(显示更新后的电子地图)。
S1.2、地图服务请求为用户终端请求：
驾驶员终端与车载单元进行用户终端请求的方法相同，故本发明以驾驶员终端为例进行详细描述：
用户通过驾驶员终端输入用户信息、车辆信息、用户终端请求和对应用户终端请求信息，驾驶员终端将上述信息发送至通信中心12；通信中心12接收并将其转发至云计算中心10；云计算中心10接收、记录、储存和分析处理所接收的用户信息、车辆信息、用户终端请求和对应用户终端请求信息，并将结果通过通信中心12发送至对应驾驶员终端，由驾驶员终端反馈给用户。
注：用户信息至少包括驾驶员信息或车主信息、乘客信息或装载物信息；车辆信息至少包括车辆号牌、车辆类型、许可证信息及地理位置信息；
一般情况下仅依据车辆信息可满足地图服务请求需要，紧急求助情况下额外依据用户信息提供增值服务。
S1.2.1、用户终端请求为查看电子地图；查看电子地图请求信息为区域信息、筛选信息；
本发明在现有查看电子地图(放大/缩小电子地图，按需进行查找/筛选兴趣点、路径预约、查看交通状况等功能)的基础上增加筛选信息，即根据用户需要，为用户提供其所要查看区域的电子地图，并根据用户需要筛选；
现有技术中仅能实现根据用户需要为用户提供该区域路侧单元信息(如信号灯)、路径信息(如高架)和兴趣点信息(如加油站)，本发明还能根据车辆信息及用户需要做进一步筛选。
云计算中心10接收上述车辆信息、查看电子地图请求和查看电子地图请求信息，调取对应区域的静态地图111和动态地图112；兴趣点信息、路侧单元信息和路径信息的筛选方法相同，故此处仅以路径信息为例进行详细描述：
云计算中心10将所接收的筛选信息与所调取的路径图层中各路径信息的属性相比对，根据比对结果将不符合筛选条件的路径关闭，将符合用户筛选条件的电子地图通过通讯中心12由用户终端4反馈给用户。
如：筛选信息为货车通行的道路，则将所调取的路径图层中禁止货车通行的路径关闭，将仅显示货车能够通行路径的电子地图发送驾驶员终端，反馈给用户。
注：如限时段/日期禁止货车通行的路径，则与电子地图对应路径处显示限时段/日期的标志，驾驶员可操作驾驶员终端查看该路径的路径信息。
用户终端请求为查看兴趣点信息、路侧单元信息或路径信息时，对应用户终端请求信息为该兴趣点信息、路侧单元信息或路径信息代码(驾驶员通过驾驶员终端选择时，驾驶员终端自动获得)。云计算中心10接收该地图服务请求后根据代码从对应兴趣点图层、路径图层及其一一对应的路侧单元图层中调取对应信息并通过通讯中心12由用户终端4反馈给用户。
本发明能够根据车辆信息对兴趣点信息、路径信息或路侧单元信息进行筛选后，只将适用的信息反馈给用户，从而改善用户体检。
S1.2.2、用户终端请求为路径规划；路径规划请求信息为出发地、目的地和计划出行时间(即，出行请求信息)；
云计算中心10分析处理操作如下：
云计算中心10接收上述车辆信息、路径规划请求、路径规划请求信息，在现有技术根据出发地、目的地和出行时间提供路径规划的基础上，还结合车辆信息和对应路径的路侧单元信息以及路径信息，对出行路径进行筛选，最后按照出行时长从低到高，为用户提供至少一条导航路径。
计划出行时间包括当前时间和计划时间；
具体包括以下步骤：
(1)、云计算中心10接收上述车辆信息、路径规划请求、路径规划请求信息后，根据出发地和目的地调取对应静态地图111和动态地图112(路径图层、路径路侧单元图层、兴趣点图层和/或兴趣点路侧单元图层。)
(2)、云计算中心10根据步骤(1)所得车辆信息(如车辆号牌、许可证信息和车辆类型等信息)，分别与所调取路侧单元图层中各路侧单元信息的非时间属性，和路径图层中各路径信息的非时间属性进行比对分析，根据属性匹配关闭不适配的路径，筛选能够通行的路径。
注：上述不适用的路径包括路侧单元信息不适配所对应的路径和路径信息不适配的路径。
如车辆类型为货车、车辆号牌尾号为单号，出行时间为2018年07月23日17时00分；则计算中心将步骤1.2.1所调取路径图层对应的各路侧单元信息和路径图层中各路径信息的车型、车辆号牌尾号等非时间属性进行比对分析，关闭属性与车型、车辆号牌尾号等车辆信息不适配的路径，如关闭所有货车和车辆号牌尾号单号禁止通行的路径。
(3)、云计算中心10对步骤(2)所得能够通行的导航路径进行路径规划，将规划所得路径按照出行时长从低到高的顺序，依次将每条路径中各路径信息和兴趣点信息及其对应的路侧单元信息的时间属性与计划到达相关路径和兴趣点及其对应的路侧单元的时间进行比对，根据比对结果，筛选准许通行的导航路径(至少一条)，并将其通过通讯中心12由用户终端4(驾驶员终端或车载单元)反馈给用户，确保为用户规划的路径始终保持通畅。
导航路径至少包括出发地、目的地之间的路段及其车道，路段到路段的路侧单元信息，里程以及预期通行时间。
用户可选择任意一条导航路径进行预览(用户终端请求为预览，用户终端请求信息为所选的导航路径)，此时在用户终端4上显示出发地和目的地之间的导航路径及里程、预期旅行时间、拥堵指数、拥堵原因及平均时速，便于用户根据路况选择合适的导航路径。
如：每个导航路径必经的优选路段包括某高架道路和地面道路，其中高架道路的货车早晚高峰期限行(7:00-9:00，16:30-18:30)，地面道路的货车不限行；
云计算中心10根据规划所得路径按照出行时长从低到高的顺序，依次将每个导航路径中到达该高架道路的预计时间与其时间属性(7:00-9:00，16:30-18:30)对比；
如所生成的第一条导航路径用时最短，但预计车辆于18:10～18:30在高架道路上通行，第二条导航路径用时较长，但其在无限制的地面道路上通行；当车辆为货车时，云计算中心10通过通信中心12将第二条导航路径发送至用户终端4；当车辆为非货车时，云计算中心10通过通信中心12将二条导航路径均发送至用户终端4，用户可以通过用户终端4进行选择；
上述时间属性包括但不限于日期限制、时段限制和有效期限制等限制信息。
本发明将车辆信息和出行信息(时间、起点和终点)相结合，智能规划其出行路径，从而确保用户按照导航路径出行时不会受许可和限制等规则的影响，解决现有导航技术中忽视复杂的交通法规，甚至导致驾驶员跟随导航出行，到达限行路段或施工路段时才发现不符合通行条件，不仅给驾驶员出行带来困扰，也为城市交通带来不必要的负担。
S1.2.3、用户终端请求为预约；预约请求信息(预约信息)包括对应用户需求信息，用户需求信息包括预约登记及其信息、预约变更及其信息和预约取消及其信息。
此时云计算中心10根据请求信息进行分析处理的操作如下：
云计算中心10将所接收的车辆信息、预约请求以及预约请求信息，通过通信中心12上传至对应第三方平台9；第三方平台9接受并根据预约请求以及请求信息进行处理，并将处理结果通过通信中心12发送至云计算中心10；云计算中心10接收、处理和保存该处理结果，并将其通过通信中心12发送至对应用户终端4。
(1)、预约登记，即表示用户对路径、兴趣点进行预约：
预约登记信息至少包括车辆号牌、预约项目(如导航路径的某一路段、停车场的某一泊位、汽车轮渡的某一班船)及预约时段。
云计算中心10将所接收的车辆信息和预约登记及其信息通过通信中心12上传至对应第三方平台9； 第三方平台9接受并处理预约登记及其信息的登记，并将预约结果通过通信中心12发送至云计算中心10；云计算中心10接收、处理和保存该预约结果，并将预约结果通过通信中心12反馈至对应用户终端4和管理终端2。
注：对兴趣点的预约与路径的预约方法一致，故在此处仅对路径预约进行详细描述。
以驾驶员通过驾驶员终端预约快速车道为例，云计算中心10分析处理操作如下：
用户可对步骤S1.2.2所得导航路径中预约快速车道(包括但不限于预约车道、专用车道、桥梁、隧道和轮渡)进行预约；用户选择预约项目(预约车道的代码)云计算中心10通过通信中心12接收该预约信息，并将预约信息通过通信中心12上传至对应第三方平台9(即，专用车道预约平台)；第三方平台9接受并处理预约信息，如果拟预约的快速车道具有富余的通行能力则接收预约，将批准的导航路径返回驾驶员终端；否则拒绝预约，推荐其他导航路径或出行时间。第三方平台9将预约结果通过通信中心12发送至云计算中心10，再由云计算中心10接收、保存预约通行平台反馈的预约结果，并将预约结果通过通信中心12发送至驾驶员终端或车载单元，反馈给用户。
注：第三方平台9(专用车道预约平台)处理预约为现有技术，故不在此处进行详细介绍。
上述快速车道可为现有高速公路或城市主干道的拥堵路段或瓶颈路段如高架路、桥梁、隧道或轮渡，还可以为交通部门用于提高快速车道和快速公交专用车道(BRT)的利用率，缓解拥堵路段的交通压力所设置的任意一个车道或几个车道，如多乘员(HOV)快速车道。
(2)预约请求信息为预约取消及预约取消信息；
预约取消信息至少包括车辆号牌，以及拟取消的预约登记信息；
当用户需求信息为取消时，云计算中心10将预约取消及预约取消信息上传至对应第三方平台9，由第三方平台9取消预约并反馈。
(3)、预约变更及其信息至少包括车辆号牌，拟变更的预约登记信息的部分或全部，以及变更后的车辆号牌、预约项目(如导航路径的某一路段、停车场的某一泊位、汽车轮渡的某一班船)和预约时段；
当用户需求信息为预约变更时，云计算中心10将预约变更及其信息通过通讯中心12上传至对应第三方平台9进行预约变更，即，按照该预约登记及预约登记信息重新进行预约；
此时云计算中心10根据预约变更后的预约项目和预约时段按照步骤(1)进行预约，如能满足预约条件，则预约变更成功并按照步骤(2)取消在先预约。如不能满足预约条件则将结果反馈给用户，用户根据实际需要取消预约或保留预约。
S1.2.4、用户终端请求为目的地导航；目的地导航请求信息为出发地、目的地和出行时间(即，当前时间)；
此时云计算中心10按照上述步骤S1.2.2为用户提供路径规划，用户可通过驾驶员终端选择适用的导航路径进行导航。即，目的地导航请求信息还可以为步骤S1.2.2中用户所选择的导航路径。
驾驶员利用驾驶员终端(或车载单元)接收导航路径进行导航，驾驶员终端(或车载单元)通过通信中心12向云计算中心10反馈所接受的导航路径(反馈的目的是便于云计算中心10计算交通路况信息)。此时将车辆地理位置置于高精度电子地图中具体的车道进行导航。
在导航过程中，驾驶员终端(或车载单元)为用户提供车道级的电子地图和地理位置定位，路段到路段的指路信息以及车辆前后方向的视频信息，并将交通系统中心1下载的导航路径中各兴趣点信息(如收费站)、路径信息(如高架)及其一一对应的路侧单元信息(如禁止泊车和滞留)的属性，通过预设的规则与车辆信息和当前时间进行对比，根据对比结果适时向用户播报适用的指路信息、指示信息、警告信息和禁令信息(如图3所示)；紧急情况下的警告信息，包括由周边车辆用户终端4发送的事故、危险、避让等警告信息。
以上所述预设的规则为针对兴趣点信息和路径信息及其对应的路侧单元信息的属性预设的报警和指示规则。
指路信息、指示信息、警告信息和禁令信息以图形、文字、语音、声光报警或触觉，或其任意组合的形式，通过驾驶员终端反馈给驾驶员。
驾驶员终端的显示器至少包括地图区域、视频区域和信息区域，地图区域、视频区域和信息区域可以 单独显示、任意两个或任意三个组合显示或轮换显示；在车辆行驶及导航过程中，地图区域显示当前位置及周边地图，包括但不限于驾驶员终端或车载单元的地理位置、车头方向角、移动速度和加速度，并实时显示导航路径及车辆移动轨迹的部分或全部；
视频区域实时显示车辆前后方向的视频信息，驾驶员可切换显示车辆前方的视频、车辆后方的视频或同时显示、交替显示车辆前后方向的视频；紧急情况下视频区域自动优先显示安全相关的视频信息，如靠近紧急车辆或校车，过于靠近行人或移动中的单车，疑似跌落物或陷阱等。车载单元除了记载行驶途中的视频信息外，可以解析安全相关的异常视频信息，如前后紧急车辆或校车，前车突然的刹车，路人或动物穿越或靠近，跌落物、障碍物或陷阱，根据解析的结果为本车驾驶员提供安全警示或应急指令，如避让、刹车，通过车车通信(V2V)为邻近车辆提供安全预警；
根据车辆位置，信息区域适时为驾驶员提供指路信息、指示信息、警告信息、禁令信息以及重要兴趣点信息，包括但不限于图形与文字，并根据洲区、国家或地区，用户还可以选择自己熟悉和习惯的图形与文字来代替所在位置的标准图形和语言文字，根据喜好进一步使用熟悉和习惯的声音来播报。
本发明在现有导航的基础上，作了以下改进：
①、路侧单元信息仅在有助于交通安全、畅通和出行便利时提示或警告用户：
车辆行驶导航过程中，驾驶员终端可根据车辆信息和行驶信息过滤不需要的路侧单元信息，为用户适时提供指路信息、指示信息、警告信息和禁令信息，改善用户体验。
注：行驶信息包括但不限于当前时间、行驶速度、加速度、行驶方向角等信息，上述信息的获取为现有技术，故不进行详细介绍。
在导航过程中，驾驶员终端将交通系统中心1下载的导航路径中各兴趣点信息和路径信息及其一一对应的路侧单元信息的属性通过预设的规则与车辆信息和行驶信息进行对比，根据对比结果向用户播报指路信息、指示信息、警告信息和禁令信息；
预设的规则指针对兴趣点信息和路径信息及其对应的路侧单元信息的属性预设的指路、指示、报警规则(限定值)和禁令，当车辆信息和行驶信息中对应值满足规则或违反禁令时，驾驶员终端向用户播报信息。
如：
路侧单元信息为禁止泊车标志，车辆加速度为负且速度低于预设值(如5km/h)且维持一定时间(如30秒钟)时，驾驶员终端提示该区域禁止泊车信息。
本发明通过将各路侧单元信息和路径信息的属性结合车辆信息和行驶信息，可以有效过滤不适用的指路信息、指示信息、警告信息和禁令信息，从而避免驾驶员不能及时从附加多种限制条件的交通标志信息中获取完整准确的信息，改善用户出行体验的同时降低交通违法的发生。
用户终端4导航工作中，根据其位置和移动方向，当位置到达预设值(如距离前方交通信号灯500m处开始显示)向用户显示该交通信号灯的状态及状态变化剩余时间，通过用户终端4向用户提供前方红绿灯的具体状态及读秒情况，从而有助于用户控制合理的行驶速度，避免交叉路口的冲刺或紧急刹车。
②、以具体的车道为用户提供导航信息：
驾驶员终端向用户提供导航服务时精确至具体的车道，能够有效避免多车道混合导航导致用户误入错误车道而走错路的不快体验或突然变更车道带来的安全隐患(如前方右转改为前方沿第4车道右转)；
如：
高速公路岔路口保持直行的路侧单元指路标志或地面标线：当车辆距离岔路口(行动点)较远的时候(如距离岔路口2千米、1千米时)，提示沿多个直行车道保持直行，直行车道之间为虚线；当车辆接近岔路口时(如距离岔路口500m时)，提示车辆只在当前车道保持直行，直行车道之间为实线，避免车辆在岔路口变更车道(如图6所示)。
分层/分色显示复杂路况：复杂立交桥的高度通过不同颜色进行分层显示，高速公路的岔路口通过不同颜色对各车道进行分色显示，城市地面道路、高架道路和隧道通过不同颜色分层显示；
支持并监督用户合法使用预约车道：预约时段内车辆位置信息靠近已预约车道，驾驶员终端可提示用户驶入预约车道；当前时间接近预约时段的时限，或根据车辆位置信息，非预约车辆误入预约车道，驾驶 员终端提示用户驶离预约车道，避免违法占用，从而改善用户的出行体验。
经过提示，用户在规定的时限内未离开或非预约车辆继续占用预约车道超过一定时间，驾驶员终端将记录车辆号牌、位置信息、日期时间及提示信息等作为证据通过通信中心12上报至云计算中心10，云计算中心10接收、记录、储存和分析处理后将违法记录通过通信中心12发送违法地和车辆属地的交通执法PC终端并通过通信中心12发送反馈至对应驾驶员终端(或车载单元)。
为缓解交通压力增设可变车道及潮汐车道使道路具有一定复杂性，如潮汐车道在早高峰由南向北单向通行，在晚高峰由北向南单向通行；如可变车道在早晚高峰为直行车道，在其他时段为左转和调头车道。
本发明可以根据实际情况将上述复杂、可预约车道对应的路径采用高精度电子地图，从而根据车辆的位置信息实现精确到车道的导航；对于普通电子地图，则采用高精度路径图层和路侧单元图层，并辅以文字、图形以及语音播报信息，为用户提供精确到车道的导航。综上，本发明能够避免驾驶员不了解道路详细信息走错车道造成违法占用、绕路情况的发生，本发明车辆位置定位至具体的车道，并以具体车道为驾驶员显示、播报指路信息(如请沿第2车道直行)，从而有效避免驾驶员误入其他车道造成的出行不便(如图6所示)。
S1.2.5、用户终端请求为紧急求助；
紧急求助信息为对应用户需求信息，包括车辆故障援助、交通事故报警、医疗救助和人身安全威胁状态救助。
在遇到交通事件时，用户可通过驾驶员终端向交通系统中心1上报交通事件监测信息，还可以根据需要，向交通系统中心1发送紧急求助的请求。
此时云计算中心10根据用户需求信息进行分析处理操作如下：
1.2.5.1、用户需求信息为车辆故障援助，表示用户车辆发生故障需要救助：
此时云计算中心10根据车辆信息筛选出最近的车辆维护服务站，将该车辆维护服务站的信息通过通信中心12发送至驾驶员终端(或车载单元)，由驾驶员终端(或车载单元)反馈给用户，云计算中心10还令该驾驶员终端(或车载单元)与对应第三方平台9(车辆维护服务站)信号相连，从而为用户提供远程诊断，视频指导救助等。
如果车辆故障影响乘客的滞留或装载物的安全，云计算中心10根据用户信息、车辆信息和用户需求信息筛选出最近的车辆租赁运输服务站，将该车辆租赁运输服务站的信息通过通信中心12发送至驾驶员终端(或车载单元)，由驾驶员终端(或车载单元)反馈给用户，云计算中心10还令该驾驶员终端(或车载单元)与对应第三方平台9(车辆租赁运输服务站)信号相连，从而提供远程诊断，根据实际情况为用户提供替换车辆、装卸作业或客运、货运服务等。
注：车辆信息中包含地理位置信息。
如果车辆故障影响交通畅通，还可以根据步骤1.2.5.2进行交通事故报警，令对应管理员通过管理终端2在电子地图上设置禁令标志、警告标志、指路标志和指示标志的路侧单元信息来引导交通，以降低车辆故障对交通的影响。
1.2.5.2、用户需求信息为交通事故报警，表示用户车辆发生交通事故；
此时云计算中心10根据车辆信息筛选出辖区内的交通执法终端(交通执法PC终端)的信息，将该交通执法终端(交通执法PC终端)的信息通过通信中心12由驾驶员终端(或车载单元)反馈给用户；云计算中心10将车辆信息和交通事故报警的用户需求信息发送至对应交通执法终端(交通执法PC终端)，交通执法终端(交通执法PC终端)的信息接收报警，并进行相应处理；
云计算中心10还将还将车辆信息和交通事故报警的用户需求信息通过通信中心12发送至交通执法终端，该交通执法终端接收并进行相应处理；
例如可按照如下步骤进行处理：
云计算中心10将车辆信息和交通事故报警请求的用户需求信息通过通信中心12发送至辖区内的交通执法PC终端，交通执法PC终端接收并根据车辆信息(位置信息)将其转发至对应交通执法移动终端，如距离事故现场最近的交通执法移动终端，交通执法移动终端将所接收信息反馈给管理员如执勤交通警察，即，指派管理员前往事故现场处理；
管理员(如执勤交通警察)根据事故对交通影响的程度，通过交通执法移动终端，在电子地图的兴趣点图层标注事故地点以及预计持续的时间，在路径路侧单元图层通向事故地点的各入口位置设置路侧单元信息，包括但不限于限速标志、禁止驶入标志，改道标志等及其时间、车型等属性；
交通事故涉及人员伤亡时，还可以通过1.2.5.3医疗救助连接对应的第三方平台9，请求医疗救助。
1.2.5.3、用户需求信息为医疗救助，表示有伤员、病人需要救助：
云计算中心10根据用户信息和车辆信息筛选出最近的医疗救助中心，将该医疗救助中心的信息通过通信中心12由驾驶员终端反馈给用户，并将用户信息和医疗救助的用户需求信息通过通信中心12发送至对应第三方平台9(医疗救助中心)，令第三方平台9根据驾驶员信息或车主信息、乘客信息以及位置信息提供救援。
云计算中心10还令该驾驶员终端(或车载单元)与对应第三方平台9(医疗救助中心)信号相连，从而为用户提供远程视频救助。
注：当用户接收该医疗救助中心的信息，以该医疗救助中心作为目的地提出路径规划或目的地导航的用户终端请求时，该用户终端请求通过通信中心12发送到云计算中心10；
云计算中心10在预设的时间内(如30min)接收到路径规划或目的地导航，以及紧急救助(医疗救助)的用户终端请求时，将用户终端请求、用户需求信息(医疗救助)和路径规划或目的地导航对应的请求信息通过通信中心12发送到该辖区内交通执法PC终端；交通执法PC终端接收并批准后，交通执法PC终端将批准信息通过通信中心12反馈给云计算中心10；
此时云计算中心10将根据路径规划或目的地导航对应的请求信息，屏蔽路侧单元信息及路径信息的限制，即，不根据用户信息和车辆信息关闭属性不匹配的路径，进行路径规划/导航，生成导航路径并通过通信中心12反馈给用户终端4，从而为用户提供通向医疗救助中心的快速通道路径规划和导航服务。
1.2.5.4、用户需求信息为人身安全威胁状态救助，表示用户遇到危险(如被挟持)需要救助：
云计算中心10根据车辆信息筛选出最近的警署，并将所接收到的用户信息和人身安全威胁状态救助的用户需求信息通过通信中心12发送至对应第三方平台9，并将其驾驶员终端(或车载单元)的位置信息通过通信中心实时发送至第三方平台9，报告驾驶员和乘客状况、车辆的位置和移动轨迹。
综上，本发明驾驶员终端与交通执法终端以及医院、警署、紧急求助中心、车辆维护服务站、车辆租赁及客运、货运服务站等第三方平台9信号相连，能够为驾驶员终端提供紧急求助功能。在出现交通事件时，能够进行事件定位、路径跟踪和远程视频救助。
S2、交通执法管理：
云计算中心10将所获取交通事件监测信息通过通信中心12同步至交通执法PC终端，即，交通执法PC终端可查看各管理路侧单元31、管理终端2和用户终端4上报的交通事件监测信息，实现对交通路况的实时监测。交通执法PC终端在出现拥堵路况和交通事件时，即时将对应交通事件监测信息转发最近的交通执法移动终端，提醒交通执法人员前往处理。
S2.1、交通执法PC终端/交通执法移动终端通过向交通系统中心1发送管理终端请求调节交通：
除现场处理交通事件外，交通执法人员可利用交通执法移动终端或交通执法PC终端将管理服务为交通事件应急管理和交通诱导服务的管理终端请求发送至通信中心12，由通信中心12发送至云计算中心10对具体的电子地图进行更新，最后通信中心12将更新后的电子地图，通过终端调用同步至各用户终端4、管理终端2和/或通过管理终端请求发送对应的管理路侧单元31。此时对应用户终端4(车载单元或驾驶员终端)向驾驶员提供相应提示或通过路径规划和导航，从而实现对交通的诱导。对应的管理路侧单元31按照更新后的路侧单元信息进行调整，如变更潮汐车道的路径方向和交通信号灯管理路侧单元31的指示，从而实现对该路段道路交通的诱导。
即，交通执法终端按照步骤S1.1所示方法对路侧单元信息进行新增、编辑、拷贝或删除后均上传至交通系统中心1更新并进行发布，从而实现对交通的诱导和管理。
如：当道路发生交通事故时，利用交通执法终端增设交通事故的路侧单元信息，封闭该段道路或一个车道，路径信息或车道信息关闭，此时交通系统中心1将该路况信息发布，并通过用户调用同步至各用户终端4，从而令驾驶员能够及时获知该路段交通路况信息，通过路径规划和导航，诱导交通的分流。
上述路侧单元信息和路径信息的属性可包含有效期，有效期结束后自动删除或恢复至处理以前状态，也可在消除交通事故后由管理终端2删除该临时路侧单元信息，将路径恢复通行状态。
如：潮汐车道早晚高峰正常变更时段外，路段出现交通流的不均衡，此时利用交通执法终端对该路段潮汐车道的路径信息和路侧单元信息进行编辑，变更潮汐车道的方向和交通信号灯的指示，上传至交通系统中心1更新并进行发布，从而实现对该路段道路交通的诱导。
上述对路侧单元信息(交通事故)和路径信息(潮汐车道)进行新增、编辑、拷贝或删除的方法如步骤S1.1所示。
S2.2、前往现场处理：
云计算中心10将其所生成的交通路况信息通过通信中心12发送至交通执法PC终端，并通过交通执法PC终端发送事件发生地最近的交通执法移动终端。
交通执法移动终端接收并向交通执法人员显示交通路况信息，从而使交通执法人员根据交通路况信息(用户终端4的位置信息和路侧单元的位置信息)前往事故现场进行相应处理(如疏导交通和紧急救援)。
S2.3、道路交通执法：
云计算中心10结合各路侧单元信息、路径信息和兴趣点信息，根据事先预设的违法判定规则，通过用户终端4所发送的用户信息和车辆信息，进行违法判定。
当判定车辆违法时，云计算中心10将违法事件记录于车辆信息对应的档案下，并通过通信中心12发送至对应车辆的驾驶员终端(或车载单元)；同时，云计算中心10将违法事件通过通信中心12发送属地的交通执法PC终端，并通过交通执法PC终端发送违法事件地理位置附近的交通执法移动终端，由交通执法移动终端提醒执法人员前往处理。云计算中心10还通过通信中心12将车辆信息同步至道路交通执法PC终端，即，交通执法PC终端可查看对应车辆的车辆号牌、车型和行车轨迹(即，对应车辆信息经云计算中心10分析处理后所得的车辆位置和时间关系地图)。
交通执法PC终端用于进行违法记录与信息的转发，交通执法移动终端用于现场处理违法。
例如：结合车辆位置电子地图及对应的路侧单元信息和路径信息分析，将行车轨迹对应的路径信息和路侧单元信息与车辆对应信息进行比对。
如某路段17:00-19:00为非浙A车辆号牌限行，则根据车辆地理位置、车辆号牌、移动速度、时钟及规则判断该车辆是否限行违法。当判定限行违法成立，则云计算中心10通过通信中心12将处理结果发送至车辆信息对应档案下记录违法事件，通过驾驶员终端(或车载单元)警告违法事件，同时通知交通执法PC终端进行违法记录，并由交通执法PC终端通知事件发生地最近的交通执法移动终端前往现场处理违法。
当路侧单元信息为全时段、全路段禁止泊车和滞留时，则根据车辆地理位置、移动速度与方向角，包括其他车辆的移动速度以及规则判断该车辆是否构成泊车和滞留违法。当判定泊车和滞留违法成立，则云计算中心10通过通信中心12将处理结果发送至车辆信息对应档案下记录违法事件，通过驾驶员终端(或车载单元)警告违法事件，同时通知交通执法PC终端进行违法记录，并由交通执法PC终端通知事件发生地最近的交通执法移动终端前往现场处理违法。
结合图5，具体案例介绍如下：
交通系统中心1采集用户终端4(车辆)的地理位置、移动速度和方向角，云计算中心10将车辆的移动速度、当前时间和所在区域是否存在路侧单元信息(禁止泊车和滞留及其时段和区域属性)比较，如果所在区域当前时段禁止泊车和滞留，且车辆移动速度为0超过一定的时间如5秒钟，交通系统中心1记录事件、发出警告并将信息(禁止泊车和滞留)发送用户，记录事件包括将时间地点、移动速度以及警告内容等记录到车辆信息所在档案下；用户可能即刻离开，也可能继续滞留；滞留的原因可能是交通拥堵或车辆故障，也可能是有意的违法，如停车、上下客或装卸货物。当交通系统中心1继续检测到车辆滞留时，再次向用户发送警告信息并记录事件。交通执法终端可以通过管理终端请求设置过滤异常、判断违法及通知执法的条件，如所有车辆全部滞留可能是拥堵，发送警告时用户反馈车辆故障不构成故意违法；累计滞留时间超过5min，或累计警告超过3次可能构成违法。满足违法条件时，交通系统中心1将违法记录登记到车辆信息所在档案下，通过驾驶员终端警告驾驶员违法事实并指令立即纠正；满足通知执法条件时，交通系统中心1将违法记录发送事件管辖地的交通执法PC终端，并由交通执法PC终端通知事件发生地最 近的道路交通移动执法终端(根据管理终端2的位置信息)。
交通系统中心1采集用户终端4(车辆)的地理位置、移动速度和方向角，云计算中心10将车辆的移动速度、当前时间和所在区域是否存在路侧单元信息(禁止机动车驶入及其时段和车辆号牌属性)比较，如果所在区域当前时段禁止非浙A号牌车辆驶入，且车辆移动方向与禁止驶入方向相同、移动速度5千米小时以上超过一定的时间如5秒钟，交通系统中心1记录事件、发出警告并将信息(禁止机动车驶入)发送非浙A车辆用户，记录事件包括将时间地点、移动速度、方向角以及警告内容等记录到车辆信息所在档案下；用户可能停止移动，也可能继续前进；移动的原因可能是时限起始以前驶入或一直滞留区域内意欲离开，或用户终端请求为紧急医疗救助时的路径规划和导航，也可能是有意的违法，如忽视标志、侥幸心理。当交通系统中心1继续检测到车辆移动时，再次向用户发送警告信息并记录事件。交通执法终端可以通过管理终端请求设置过滤异常、判断违法及通知执法的条件，如查阅车辆的历史位置及移动方向可知是否时限起始前驶入或一直滞留区域内意欲离开，短距离的移动或紧急医疗救助时的移动等可能不构成故意违法；累计移动距离超过500米，或累计警告超过3次可能构成故意违法。满足违法条件时，交通系统中心1将违法记录登记到车辆信息所在档案下，通过驾驶员终端警告驾驶员违法事实并指令立即纠正；满足通知执法条件时，交通系统中心1将违法记录发送事件管辖地的交通执法PC终端，并由交通执法PC终端通知事件发生地最近的道路交通移动执法终端(根据管理终端2的位置信息)。
S3、交通路况路径规划和预告，其实现方法如下：
S3.1、交通执法PC终端/交通执法移动终端通过通信中心12将交通路况路径规划请求及交通路况路径规划请求信息发送云计算中心10；
交通路况路径规划请求信息包括出发地、一个以上的目的地及更新周期；
S3.2、云计算中心10接收、记录、储存交通执法PC终端/交通执法移动终端发送的交通路况路径规划请求及交通路况路径规划请求信息，并根据交通路况路径规划请求信息执行路径规划，按照更新周期自动生成出发地交通路况路径(如绿色即畅通、橙色即拥挤和红色即拥堵)及预告结果(即，按照更新周期重复生成出发地交通路况路径及预告结果)，并将该出发地交通路况路径和预告结果通过通信中心12发送至对应交通执法PC终端/交通执法移动终端；
注：出发地路径规划为现有技术，故不在此处详细告知。
预告结果至少包括目的地名称、里程、预期旅行时间、畅通或拥堵；
S3.3、交通执法终端接收并向交通执法人员显示出发地交通路况导航路径及预告结果，交通执法人员根据出发地交通路况导航路径及预告结果利用交通执法终端通过通信中心12向云计算中心10发送映射请求和映射信息，将交通路况路径及预告结果映射显示位于出发地的指定管理路侧单元31上显示；
映射信息至少包括出发地交通路况路径、预告结果和指定管理路侧单元31的路侧单元信息；
S3.4、云计算中心10接收映射请求和映射信息，将步骤S2.3.3中所生成的出发地交通路况路径及预告结果通过通信中心12同步至对应指定管理路侧单元31，由管理路侧单元31进行显示；
注：当云计算中心10接收映射请求和映射信息后，步骤S3.2中按照更新周期更新的出发地交通路况路径及预告结果，也将通过通信中心12同步至对应交通执法终端和管理路侧单元31。
此时，途径该管理路侧单元31的用户可根据管理路侧单元31所显示的交通路况路径及预告结果调整行驶路线，如，管理路侧单元31显示其所在位置(出发地)到各出口(目的地)的交通路况路径及预告结果，路过该管理路侧单元31的车辆(即使该车辆没有用户终端4)即可根据交通路况路径及预告结果及时调整其行驶路线，确保通行的畅通。
S4、发布交通事件监测信息的方法：
管理路侧单元31、管理终端2和用户终端4采集并向交通系统中心1上报交通事件监测信息：
管理路侧单元31可监测所在位置的交通事件监测信息(如气象监测信息、交通流量等)并通过通信中心12上传至云计算中心10，还可通过路侧单元-交通系统中心(I2N)通信，将交通事件监测信息通知适用的用户终端4采取避让，如改变出行计划、绕开交通事件路段，通知管理终端2采取应急响应措施，如关闭交通事件路段、关闭一个车道，设置路侧单元等；
管理员管理终端2可通过管理路侧单元31向通信中心12上报交通事件监测信息(如塌方、淹水、交 通事故等)，还可直接向通信中心12上报交通事件监测信息；
管理终端2在发现交通事件时，还可通过交通路况路径规划和预告及其映射请求的方法通知非用户终端4驾驶员采取避让，如改变行驶路线绕开交通事件路段，还可通过上报管理服务为交通事件应急管理或交通诱导服务的管理终端请求主动采取应急响应措施，如关闭交通事件路段、关闭一个车道，设置路侧单元等。
用户终端4可通过管理路侧单元31向通信中心12上报交通事件监测信息，还可直接向通信中心12上报交通事件监测信息；
注：管理终端2与用户终端4上报交通事件监测信息的方式可根据实际情况选择手动或自动。
用户终端4还可通过车车通信(V2V)向短程信号范围内其他用户终端4发送交通事件监测信息。
云计算中心10接收、记录、储存、更新和分析处理所有上传的交通事件监测信息，生成并更新实时的交通路况信息，同时还根据交通事件性质及其严重程度通过通信中心12将更新后的交通状况信息根据交通事件所在位置(上报该交通事件监测信息管理路侧单元31、用户终端4或管理终端2的位置信息)发送至对应管理路侧单元31进行显示，和/或发送至相应管理终端2和用户终端4(该区域内管理终端2及其他用户终端4)进行提示和警告；
云计算中心10还对交通事件监测信息进行分析处理，根据该交通事件监测信息判断是否更新电子地图中心11进行更新；
如判断需要更新，则根据交通事件监测信息更新电子地图中心11中对应的电子地图(静态地图111和各动态地图112)，并将更新后的电子地图(静态地图111和各动态地图112)，通过通信中心12同步至调用其的用户终端4和管理终端2。
如施工道路恢复通行，对应路径图层中仍显示该道路施工关闭，云计算中心10则根据通过该道路的用户终端4、管理终端2以及该路径对应的管理路侧单元31所上报的交通事件监测信息判断该路况为可通行，则在更新交通路况信息的同时还应根据交通事件监测信息更新该路径信息，并将更新后的路径图层，通过通信中心12同步至调用其的用户终端4和管理终端2。
以用户终端4为例进行详细阐述发布交通事件监测信息的方法：
用户终端4可通过以下3种方法发布交通事件监测信息：
如车辆发生或驾驶员发现交通事件时，利用用户终端4手动/自动发送交通事件监测信息，此时驾驶员利用驾驶员终端将采集现场视频信息，并同用户信息和车辆信息一起进行发布，即，进行交通事件报告。
方法1、用户终端4的车载单元通过车车通信(V2V)向短程信号范围内其他用户终端4(如前后车辆)对应的用户终端4发送交通事件监测信息；
如当发生或发现交通事件时，车载单元通过V2V通信向周边车辆发送交通事件监测信息(如，物品掉落信息)，从而及时向周边车辆预警，有效避免因突发情况造成的交通事故。
注：V2V报告交通事件，可在毫秒级的时间内通知周边车辆避免交通事故。
方法2、驾驶员终端或车载单元将交通事件监测信息发送至管理路侧单元31，由管理路侧单元31将该交通事件监测信息通过基础设施-交通系统中心通信(I2N)有通信中心12发送至云计算中心10。
方法3、驾驶员终端或车载单元将交通事件监测信息直接发送至通信中心12；通信中心12将所接收的交通事件监测信息转发至云计算中心10；
注：管理终端2上报交通事件监测信息同上述方法2和方法3。
