Description

交通信息管理服务器、导航终端及其方法 Traffic information management server, terminal and method navigation

技术领域 FIELD

本发明涉及导航领域,特别是一种管理向多个导航终端提供交通信息的交通信息管理服务器以及一种搜索移动物体从起点到终点的经由路径,引导所述移动物体的导航终端和相应的方法。 The present invention relates to the field of navigation, and particularly to a management server managing traffic information providing traffic information to a navigation terminal, and for searching a plurality of moving object from the origin to the destination via a path, directing the moving object navigation terminal and corresponding method .

背景技术 Background technique

如今的载有电子地图的导航终端能根据存在硬盘或DVD等介质上的电子地理里的地理和交通规则信息搜索路径。 Today's carrying electronic map navigation terminal is capable of geography and traffic rules geographic information search path on the electronic and other media in the presence of a hard disk or DVD based. 通过输入起终点,用户可以根据导航终端的计算结果选择路线。 Since by the end of input, the user can select the route navigation terminal according to the calculated results. 在导航行程中,系统告诉用户应该行驶的路径,比如应该向哪个交叉路口行驶等。 In the navigation route, the system tells the user should travel the path, such as to which intersection should travel and so on. 被用于路线计算的数据来自于电子地图里的数据库, 一般在l年内更新几次。 Data is used to calculate the route from the electronic map in the database, usually updated several times at l year.

然而,在有些发展中城市里,道路还在频繁的建设,交通规则也经常改变,兴趣点(地图上标识建筑物等一些场所的地标)也经常发生变化。 However, in some developing cities, the roads are still frequent construction, traffic rules often change, points of interest (some of the places on the map to identify buildings and other landmarks) frequently change. 通过人工釆集更新的传统办法无法在电子地图上给用户提供最新的信息。 Unable to provide the latest information to the user through the traditional way preclude the artificial set of updates on the electronic map. 基于这些"旧"的信息,导航终端的计算路线经常给用户带来不便,错误的指示浪费了用户的时间甚至金钱。 Often cause inconvenience to the user to calculate routes based on these "old" information navigation terminal, user error indicates a waste of time and even money.

为了避免上述情况,电子地图提供商不得不更加频繁的通过人工外业采集等方法去更新地图数据,或者通过成立联盟包括政府单位在内去保证数据的更新频率。 To avoid this, the electronic map providers have to go through more frequent manual collection methods outside the industry to update the map data, or by a coalition including government agencies, including to ensure the update frequency of the data. 然而,这样仍然需要耗费大量的金钱和时间, 并且不是所有的地图提供商都能做到这点。 However, this still requires a lot of money and time, and not all map providers can do. 因此有一种需求,需要自动采集,组织,鉴别,和提供最新的,值得信赖的,和详细的数据给导航终端。 Therefore there is a need, the need for automatic capture, organize, identify, and provide current, reliable, and detailed data to the navigation terminal.

美国的一个专利,"通过反馈而更新,增强或改进地理数据库的方法和系统"(6516267),描述了一个系统和方法,通过道路的检测器反馈信息发现,更新和增强地理数据库。 U.S. Patent No. A, "updated by feedback, enhancing or improved method and system geographic database" (6,516,267), describes a system and method by the detector feedback path discovery, the geographic database updates and enhancements. 反馈信息包含有信息的可信程度以表示反馈信息和实际地理特征的匹配程度。 Feedback information includes trust level information to indicate the actual degree of match feedback information and geographic features. 然而,这个反馈信息的可信程度的增加或降低只考虑了信息来源的更新频度,却没有考虑到导航终端用户使用该信息的结果,不包含真正的用户反馈过程。 However, the credibility of the feedback information to increase or decrease the frequency of updating only consider sources of information, but not take into account the result of the end user navigation information does not include the real user feedback process. 所以这种实际上是单一方向的信息采集更新方法并不能保证信息的准确性和可信程度。 So this is actually a method to update the information collected in one direction does not guarantee the accuracy and credibility of the information.

还有一些网站的公开服务,比如:http://www.poihandler.com, 在给用户提供免费或者收费的更新数据,用于不同的导航终端的共享。 There are also sites of public services, such as: http: //www.poihandler.com, giving users free of charge or update data, for sharing different navigation terminals. 这种"贡献和索取"的模式在互联网中非常普遍,然而,这些信息的信赖程度却很难给用户提供保证。 This "contribution and ask" model is very common on the Internet, however, the degree of trust that information is difficult to provide users with assurance. 如果用户在使用这些更新数据中出现了问题,反馈过程往往是自发和无法控制的。 If you use these updated data there is a problem, the feedback process is often spontaneous and uncontrollable. 其他使用者很难及时并准确得到这类的反馈。 Other users timely and accurately is difficult to get this kind of feedback.

丰田Mapmaster在名古屋ITS世界大会上发表了一篇论文,是关于通过探测车数据保持地图数据的更新。 Toyota Mapmaster published a paper in Nagoya ITS World Congress, it is about keeping updated map data by detecting vehicle data. 它描述了一种算法,通过结合交通信号和探测车数据,判断单行线或禁行线。 It describes a method, and traffic signals by combining the probe car data, determines a single line or row line forbidden. 然而,正如其指出的,车载系统的探测数据准确性,会影响更新信息的可信程度。 However, as pointed out in its detection accuracy of the data on-board system will affect the credibility of the updated information. 他们不得不通过现场査看来确认地图和数据的不匹配的地方。 They have to be confirmed by the local scene to view the map and the data does not match. 这仍然耗时耗力。 This is still time-consuming and labor-intensive.

Lc is a schematic configuration diagram of the traffic information database traffic information management server stored in the storage unit. 在存储单元105的交通信息数据库中,每条交通信息根据地图上的位置ID号码(比如道路路链编号,路口编号,兴趣点编号等)进行排列。 Traffic information database in a storage unit 105, traffic information for each position are arranged according to the ID number (such as road road link number, intersection number, number of points of interest, etc.) on the map. 每条交通信息都被划分为多个类别(比如交通规则,兴趣点,交通事件,道路状况等)存在不同的表类中。 Each traffic information is divided into categories (such as traffic rules, points of interest, traffic incidents, road conditions, etc.) there are different table classes. 主要数据为交通信息内容(比如某道路路口限制左转等),并且有根据这些交通信息内容和类别划分的交通信息接收用户类别(比如所有人, 私家车,商用车,公务车,行人,自行车等),以及该信息的信赖度(比如5星级,4星级等)。 The main data for the traffic information content (such as a road junction turn left restrictions, etc.), and there are categories of users to receive traffic information based on the traffic information content and category (such as owners, private cars, commercial vehicles, public service vehicles, pedestrians, bicycles etc.), and the reliability of the information (such as 5-star, four star etc.). 在管理服务器收到导航终端发送的交通信息请求消息的时候,通过管理服务器的控制单元(106)通过和存储单元(105)的通信,根据上述交通信息数据库里的上述字段对数据进行各种条件的检索,提取交通信息数据库中的相应的交通信息,生成交通消息发送给导航终端。 When the management server receives the navigation terminal transmits the traffic information request message, the data conditions by a control unit (106) via the management server and a storage unit (105) communication based on the traffic information in the database field retrieving, extracting traffic information corresponding to the traffic information database, generating a traffic message transmitted to the navigation terminal. 下载的交通消息的示例在图8中有说明。 Example downloaded traffic message are illustrated in FIG.

图ld是交通信息管理服务器中更新交通信息数据库的流程图。 Figure ld is a flowchart of the traffic information database of traffic information management server updates. 首先控制单元106根据不同信息来源的渠道对交通信息进行数据格式转换208,统一成一个规定的交换格式,存储在存储单元105的交通信息数据库中。 First, the control unit 106 performs data format conversion 208, unified into a predetermined format of traffic information exchange channels according to different sources of information, a traffic information storage unit 105 stored in the database. 在交通信息数据表中的每条交通信息都是根据位置ID, 信息内容和信赖度而排序的,每条ID的内容根据信息的类别不同而具有唯一性。 Each traffic information in the traffic information data table are based on the location ID, the content and reliability information are ordered, the content ID of each information varies according to the type unique. 每条信息的信赖度并非一成不变,根据信息来源的数量和反馈而变。 The reliability of each piece of information is not static, the number of sources of information and feedback becomes. 当在同一位置ID上出现多条信息来源(比如政府部门,和道路信息采集系统都有对于某条道路的交通限制信息),如果信息内容是相同的,系统保持信息内容不变,同时设置该条信息的信赖度为这些信 When there is multiple sources of information at the same location ID (such as government departments, and road information collection systems have information about traffic restrictions for a road), if the content is the same, the system remains unchanged the information content, and set the pieces of information about the reliability of these letters

息来源中信赖度最高的级别;如果信息是相反的,系统先比较新旧信息的信赖度,如果新信息的信赖度更高,则改变信息内容,否则暂时保持原信息内容不变,同时继续检测关于该位置ID的新信息,当与原信息内容相反的信息数量增加到一定程度(比如占总信息数量的比例超过50%),则改变该条信息的内容,并将其信赖度修改。 The highest level of interest in the reliability of the source; if the information is reversed, the reliability of the system to compare the old and new information, if higher reliability of new information, changing information content, or to temporarily maintain the original content unchanged, while continuing to detect new information about the location of the ID, the original content when opposite quantity information to a certain extent (for example, the ratio of the total amount of information more than 50%), changing the content of the piece of information, reliability and modifications thereof. 修改信赖度的原则是在选择最高信赖度的信息来源的基础上,根据使用该信息的用户的反馈变化。 Modifying the selection principle is the reliability of information sources on the basis of the highest reliability, the feedback information is changed according to the user. 如果正面的反馈达到一定的数量,比如超过总反馈量的50%,则增加信赖度一级;如果负面的反馈达到一定的比例, 比如超过总反馈量的50%,则降低信赖度一级。 If the positive feedback reaches a certain amount, such as more than 50% of the total amount of feedback, increase reliability level; if negative feedback reaches a certain percentage, such as more than 50% of the total amount of feedback, reduce the reliability level. 依此类推。 So on and so forth.

航终端交互执行交通信息管理的流程图。 Air traffic information management terminal interactive flow chart of execution.

参考图le,首先,在步骤ll,交通信息管理服务器104通过接口单元107从一个或多个导航终端108接收对交通信息的请求。 Referring to FIG Le, first, in step ll, the traffic information management server 104 receives a request for traffic information unit 108 through the interface 107 from the one or more navigation terminals. 在步骤12,交通信息管理服务器104的控制单元106根据导航终端的请求,从交通信息数据库中提取出包括移动物体在经由路径上的所述位置ID、对应所述位置ID的交通信息,以及与所述交通信息对应的信赖度 12, the control unit 104 of the traffic information management server 106 according to a request of the navigation terminal, extracted from the traffic information database at step out on said location ID includes a moving object via a path, said location ID corresponding to the traffic information, and with corresponding to the reliability of the traffic information

并生成交通消息,以及在步骤13通过接口单元107将该交通消息发送到导航终端108。 And generating a traffic message, and transmitting to the navigation terminal 108 in step 107 via the interface unit 13 the traffic message. 导航终端108在通过其接口单元22接收到该交通消息之后,可以将该交通消息作为经由路径上的、由所述交通消息构成的交通信息管理表存储在存储单元23中,以便表示单元表示与所述搜索的经由路径上的所述位置ID对应的所述信赖度。 After the navigation terminal 108 receiving the traffic message through the interface unit 22 which, as can be via the traffic message, the traffic information management table storage constituted by the traffic message on the path in the storage unit 23, so as to represent the unit represented the reliability of the via positions corresponding to the ID on the search path. 在步骤14,如果导航终端108发送了反馈信息,则交通信息管理服务器104接收该反馈信息,并在步骤15由控制单元106对所述交通信息数据库中的与所述位置ID对应的所述信赖度进行更新,否则结束。 In step 14, if the navigation terminal 108 transmits the feedback information, the traffic information management server 104 receives the feedback information, and at step 15 by the control unit 106 in the traffic information database with the location ID corresponding to the trust of the update, or end.

图3是交通信息管理服务器和导航终端之间执行交换工作以交换和更新交通信息的另一个示例流程图。 FIG 3 is performed between the exchange of the traffic information management server and the navigation terminal and the exchange in another exemplary flowchart updated traffic information.

该流程是用户在行程的起点开始的。 The process is the user at the beginning of the trip began. 第一次的路线计算在导航终端的本地完成。 The first is done locally calculated route navigation terminal. 当从起点到终点的路径列表产生后,该列表通过无线通信网络(GPRS, C匿A, WiMAX等)被发送到交通信息管理服务器104。 When the paths from the beginning to the end list is generated, the list is sent to the traffic information management server 104 through the wireless communication network (GPRS, C hide A, WiMAX, etc.). 交通信息管理服务器104根据该列表在存储单元105的交通信息数据库中进行搜索,如果发现有更新的交通信息,交通信息管理服务器首先检査该信息的类别。 Traffic information management server 104 searches the database in storage unit 105 of the traffic information based on the list, if an update is found traffic information, traffic information management server first checks the category of the information. 如果是兴趣点信息,不会影响路径的计算结果。 If a point of interest information, it will not affect the results of the path. 如果是交通规则信息,有限制的该路径将被发送回导航终端,导航终端需要重新计算路线,再次发送给交通信息管理服务器进行检查。 If the information is traffic rules, there are restrictions that path will be sent back to the navigation terminal, the terminal needs to recalculate the navigation route, sent again to check traffic information management server. 通过用户使用导航终端与交通信息管理服务器的信息交换功能,能找到最合理的行驶路线。 By using the navigation user terminal and information exchange function traffic information management server, to find the most reasonable driving route. 当导航开始后,用户可以选择是否启动导航终端108的反馈功能,也可以预先设置默认的反馈状态(激活或休眠),如果启动反馈功能,GPS数据记录将自动开始记录和匹配路线,当用户抵达目的地结束本次导航后,导航终端108自动生成一个匹配结果列表,并通过接口单元22发送给交通信息管理服务器的控制单元106, 其可以通过用户的该次行程进一步检验该更新信息的信赖度。 When the navigation starts, the user can select the feedback function on or off the navigation terminal 108 may be provided in advance by default feedback state (activated or sleep), if the enabling feedback function, GPS data recording will automatically start recording and a matching route, when the user arrived after the end of this navigation destination, the navigation terminal 108 automatically generates a matching result list, the control unit 106 and transmits traffic information to the management server through the interface unit 22, which may further verify that the information is updated by the user strokes the reliability . 如果没有匹配失败的情况,交通信息管理服务器104将增加该更新信息的信赖度,如果有匹配失败的道路,系统将请求用户通过文字或语音界面输入匹配失败原因,或者通过自动识别的车载图像系统向中心报告。 If there is no match fails, the traffic information management server 104 will increase the reliability of the update information, if there is a failure to match the road, the system requests the user via text or voice reason for the failure to match the input interface, or by the system automatically recognizes the image of the vehicle report to the center. 如果证明该更新信息是错误的,交通信息管理服务器将降低该信息的信赖度。 If it is proved that the updated information is wrong, the traffic information management server will reduce the reliability of the information. 如果匹配失败的原因是由用户自己造成的,比如没有按照导航路线行驶,或临时更改目的地,导航终端将通过接口单元22发回一 If the cause of the failure is caused by matching the user's own, for example, did not follow the navigation routes, or temporarily change the destination, the navigation will be sent back to a terminal through the interface unit 22

个未明原因给交通信息管理服务器104,通信息管理服务器104放弃本次反馈结果。 Unknown cause a management server 104 to the traffic information, through the information management server 104 to abandon the result of this feedback.

图4是检验来自于探测车或检测器的道路信息的流程图。 FIG 4 is a flowchart of the road information from the probe car or the test detector. 如果采集的信息来自于道路上的车辆,比如探测车,根据其GPS数据,交通信息管理服务器能生成最高速度,交通方向和行驶路线等信息。 If the information collected from the vehicles on the road, such as probe vehicles, according to their GPS data, traffic information management server can generate maximum speed, direction of traffic and driving directions, and more. 通过统计分析计算速度在某一个时段超过某一个速度限制(根据目前的地图属性数据)的比率,比如概率超过40%,交通信息管理服务器可以推测出该道路的限制速度可能已经发生了改变。 By statistical analysis to calculate the speed at a certain period exceeds a certain speed limit (based on the current map attribute data) ratios, such as the probability of more than 40%, traffic information management server can be speculated that the speed limit of the road may have changed. 通过分析判断交通方向和行驶路线,交通信息管理服务器可以知道哪个转弯方向是禁止的, 哪条道路是关闭的或者是单行线。 By analysis to determine the direction of traffic and travel routes, traffic information management server can know which direction the turn is prohibited, which road is closed or one-way street. 分析探测车的数据不是仅仅基于某一个时刻的车辆行驶方向,位置,速度,或某一辆车的地图匹配路线, 而是根据平均速度范围,行驶方向,和车辆类型等其他信息在每5分钟内, 一天24小时中的交通行为规律,因为大部分的交通规则是有时间限制和车辆类型限制的。 Analysis probe car data is not based on only one direction of vehicle travel time, position, speed, or a vehicle route map matching, but the average speed range based on other information, traveling direction, and vehicle type or the like every 5 minutes inside, traffic behavior in the law 24 hours a day, as most of the traffic rules is a time limit and vehicle type restrictions. 这些方法可以尽量避免车载系统自身计算的错误和片面。 These methods can avoid errors and one-sided in-vehicle computing system itself.

如果采集的信息来自于道路上安装的检测器,比如感应线圈,摄像头,超声波探测器,微波探测器等,交通信息管理服务器可以通过统计分析的方法对各个检测断面上的交通流进行分析,发现道路的交通流特征,生成交通状况变化情况。 If the information collected from the detectors installed on the road, such as an induction coil, a camera, an ultrasonic probe, microwave detectors, traffic information management server may analyze the traffic flow on the respective detecting section by means of statistical analysis, found flow characteristics of road traffic, generate traffic situation changes. 最高速度和交通方向可以被安装在车道上的感应线圈判别。 Maximum speed and the direction of traffic may be installed in the induction coil on the lane discrimination. 转向情况可以通过有地面指向标志的车道进行判别。 The situation can be turned to discriminate by pointing to the ground have marked lanes. 比如,如果一个路口的由西向东的最左边的车道感应到有一辆小汽车通过,而在一个信号灯周期内,由北向南方向的靠近里面的车道也感应到有车驶入,说明有车辆在这个路口的绿灯时间内进行由西向南的左转弯行驶。 For example, if a crossing from west to east induction of the far left lane to pass a car there, but in a light cycle, from north to south near the inside lane is also sensitive to the direction into the car, indicating the vehicle green time within this intersection were traveling from west to south left turn. 同时,行驶路线的判别也可以通过摄像头对车牌进行跟踪拍摄进行分析。 Meanwhile, the travel route determination can also be analyzed by tracking shot the camera on the license plate.

图5显示了一个具有信息交换功能的车载导航终端的实例。 Figure 5 shows an example of a vehicle navigation terminal having exchange function of information. 该导航终端与车内的一台面向车头前方拍摄的摄像头404,和一个用于上传和下载数据的无线通信天线405相连。 The car navigation terminal with a forward-facing front photographing camera 404, and a wireless communication antenna for uploading and downloading data 405 is connected. 在导航地图显示屏(401)中, In the navigation map display (401)

有两个例子显示。 There are two examples show. 在例1中,车1正在驶向路口1,准备进行左转抵 In Example 1, the vehicle 1 is heading junction 1, ready to turn left against
