Description

车道调度方法、车道信息获取方法、车辆及管理设备 技术领域
本发明涉及智能交通领域,具体涉及车道调度方法、车道信息获取方法、车辆及管理设备。
背景技术
交通的实质也就是利用道路将人或物从一个地点运输到另一个地点,因此道路是交通系统中最为关键的资源,智能交通系统重点要解决交通系统的安全和效率问题,因此如何安全高效地利用道路这一资源就成为其首要的任务,智能交通系统旨在通过集成应用先进的信息、通信、传感、控制和计算机等技术,建立大范围、全方位发挥作用并且实时、准确、高效的综合交通运输管理系统,智能交通系统可以有效利用交通设施、减少交通负荷和环境污染、保证交通安全、提高运输效率,是交通系统未来的发展方向,也是智能城市的重要组成部分,智能交通系统的发展跟物联网的发展密不可分,是交通运输行业物联网化的体现,其中贯穿了交通系统中各种信息的收集、处理、发布、交换、分析和利用,如图1所示,智能交通系统的主要参与者涉及道路基础设施、车辆、用户和管理中心等,整个系统可以由车辆控制、交通信息、交通管理等子系统构成,其中,车辆控制子系统负责安全高效地控制车辆的行驶,交通信息子系统负责准确及时地采集、处理和交换交通参与者的信息,交通管理子系统负责根据交通信息对交通参与者的行为进行协调控制。
目前业界在如何规划道路(例如区域覆盖和路口设置)、如何设置道路相关基础设施(例如信号灯和分流带)等方面已有不少的实践经验,但由于道路本身的相对静态和以往使用的一贯粗放,在如何精细化利用这一资源上还缺乏探索,随着车辆控制技术的发展,从车辆获取内部和外部信息供驾驶员参考,到车辆综合各方面信息协助驾驶员控制越来越多的功能,再到车辆完全自动控制自身,车辆在交通系统中更快速更智能的反应行动也要求对其使用道路资源的情况进行更精确的控制。
现有的方法为:管理中心记录图2中两个路口B到E之间的道路称为自然路段BE,将自然路段中已划分出的车道称为自然车道,自然路段BE中横向划分的三个车道分别称为自然车道BE1、BE2和BE3,在自然车道BE1、BE2和BE3的路口B和路口设置车辆监测仪,当车辆经过路口B及车辆驶出路口E时,车辆监测仪向管理中心发送车辆驶入或车辆驶出信息,管理中心根据车辆驶入或车辆驶出信息可以确定自然车道BE1、BE2和BE3上的车辆数,从而对自然车道BE1、BE2和BE3的车道资源的占用情况有大致的了解,当自然车道BE1上车辆数目超过阈值(即自然路段BE1的长度=前后车间安全距离*车辆数)时,管理中心发出提示信息,用于提示自然车道BE1已经拥挤,限制后续车辆进入自然车道BE1,或者通知后续车辆换道自然车道BE2。
但是,现有的方法中由于道路中的自然路段的长度可变范围极大,例如商业区域两个相邻路口之间的距离和高速公路两个相邻出入口之间的距离就大相径庭,现实情况中在长度很长的自然路段上,车辆进行变道是普遍存在的,例如,图2中车辆1进入BE1,如果在车辆1到达BE1的中途时,BE1上出现堵车情况,而BE1的邻道BE2上是空闲的,如果车辆1变道至BE2,管理中心还是会将车辆1计算到BE1的车辆数目中,那么管理中心判断BE1上车辆数目超过阈值是不准确的,发出的提示信息不准确,BE1是还能驶入后续的车辆;如果车辆1不变道,空闲的BE2无法利用,不管车辆1是否变道,都会导致道路资源利用的效率不高。
发明内容

所述管理设备将所述逻辑车道在所述车道使用时间内的所述车道状态信息设置为预留状态;当所述车辆驶入所述逻辑车道时,接收所述车辆发送的驶入通知;根据所述驶入通知将所述逻辑车道在所述车道使用时间的剩余时间部分内的所述车道状态信息设置为占用状态;当所述车辆驶出所述逻辑车道时,接收所述车辆发送的驶出通知;根据所述驶出通知将所述逻辑车道在所述车道使用时间的剩余时间部分内的所述车道状态信息设置为空闲状态。
管理设备将道路资源分配响应发送至车辆之后,将车道使用时间内逻辑车道的车道状态信息设置为预留状态,这样在其他车辆有同样的请求时,不会分配相同的逻辑车道,以免两台车辆同时驶入同一条逻辑车道,导致安全事故;当车辆驶入和驶出逻辑车道时,车辆会发送驶入和驶出通知,管理设备根据通知对逻辑车道在车道使用时间的剩余时间部分内的车道状态信息进行更新,有利于管理设备实时的掌握所有整个道路的情况,从而更准确的进行道路资源的分配。

当车辆在车道使用时间内未驶入逻辑车道时,即表示车辆可能未按照管理设备反馈的道路资源分配响应行驶,例如,车辆在该逻辑车道之前进行了减速 行驶,导致未能在车道使用时间内驶入该逻辑车道,需要根据新的车道状态信息重新为车辆分配新的道路资源,生成第一道路资源更新通知,并将第一道路资源更新通知发送至车辆,以满足车辆对于道路资源的需求。
结合本发明第一方面第四实施方式,本发明第一方面第六实施方式中,所述车道调度方法还包括:

如果车辆按照道路资源分配响应驶入逻辑车道,但是车辆发生了故障,使得车辆停止或者减速,那么车辆在车道使用时间内无法驶出逻辑车道,管理设备对该车辆使用该逻辑车道的车道使用时间进行增加,生成第二道路资源更新通知,并向车辆发送第二道路资源更新通知,提高了管理设备在车道调度过程中的灵活性。
结合本发明第一方面第四实施方式,本发明第一方面第七实施方式中,所述车道调度方法还包括:
当所述逻辑车道在所述车道使用时间前预留状态发生变化时,获取所述逻辑路段的新的车道状态信息;根据所述新的车道状态信息为所述车辆分配新的道路资源,并根据所述新的道路资源生成第三道路资源更新通知,所述第三道路资源更新通知包含更新的车道标识及更新的车道使用时间,所述更新的车道标识用于标识所述管理设备为所述车辆更新的逻辑车道,所述更新的车道使用时间表示所述车辆使用所述更新的逻辑车道的时间;向所述车辆发送第三道路资源更新通知。
当在车道使用时间前,逻辑车道的预留状态发生变化,例如,逻辑车道上发生车辆故障,车辆维修人员上报维修时间,车道使用时间包含在维修时间内,那么在车道使用时间内逻辑车道无法行驶车辆,将逻辑车道在车道使用时间内的预留状态改设为占用状态,对分配给车辆的逻辑车道及车道使用时间进行更新,生成第三道路资源更新通知,将第三道路资源更新通知发送至该车辆,使 得车辆可以避开原来分配的逻辑车道,改行其他逻辑车道顺利通过逻辑路段,提高了安全性。

具体实施方式
本发明实施例提供车道调度方法、车道信息获取方法、车辆及管理设备,用于管理设备根据道路资源分配请求为车辆分配逻辑车道,使得车辆数目众多时,管理设备可以全局的进行道路资源的分配,实现车辆的精细化管理,提高了道路资源的利用率和车辆行驶的安全性。
为了使本技术领域的人员更好地理解本发明方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分的实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
首先简单介绍本发明应用的系统构架或场景。
本发明中的车道调度方法应用于如图1所示的智能交通系统中,智能交通系统的主要参与者涉及道路基础设施、车辆、用户和管理中心等,整个系统可以由车辆控制、交通信息、交通管理等子系统构成,其中,车辆控制子系统负责安全高效地控制车辆的行驶,交通信息子系统负责准确及时地采集、处理和交换交通参与者的信息,交通管理子系统负责根据交通信息对交通参与者的行为进行协调控制,管理中心主要包括管理设备,管理设备具有道路资源分配等功能,车辆上集成或者安装具有与管理设备可实时通信的设备,使得车辆可以协助用户进行驾驶,或者可以完成自动驾驶功能,车辆还具有定位功能设备,道路基础设施包括信号灯及路边测速仪等设备。
管理设备以服务器为例,如图11所示为本发明提供的一种服务器的结构示意图,该服务器可因配置或性能不同而产生比较大的差异,可以包括一个或一个以上中央处理器(central processing units,CPU)1122(例如,一个或一 个以上处理器)和存储器1132,一个或一个以上存储应用程序1142或数据1144的存储介质1130(例如一个或一个以上海量存储设备)。其中,存储器1132和存储介质1130可以是短暂存储或持久存储。存储在存储介质1130的程序可以包括一个或一个以上模块(图示没标出),每个模块可以包括对服务器中的一系列指令操作。更进一步地,CPU1122可以设置为与存储介质1130通信,在服务器上执行存储介质1130中的一系列指令操作。
服务器还可以包括一个或一个以上电源1129,一个或一个以上无线网络接口1150,一个或一个以上输入输出接口1158,和/或,一个或一个以上操作系统1141,例如Windows ServerTM,Mac OS XTM,UnixTM,LinuxTM,FreeBSDTM等等。
管理设备和车辆上具有的交通图是一致的,智能交通系统预先将包括一条以上自然车道的自然路段(即已建设完成的在一定区隔范围内的道路)划分成两个以上的逻辑路段,优选的,逻辑路段设置的长度不小于前后车间行驶安全距离,同时出于智能交通系统更加精细化调度的要求,逻辑路段的长度应该在设置的尽量接近前后车间行驶安全距离,而前后车间行驶安全距离是根据道路的环境所决定的,在交通图上对自然路段、逻辑路段及逻辑路段的逻辑车道用标识进行表示,并且将形成的新交通图通过通信网络发送给车辆,如图2所示的自然路段BE(长度为300m),车速限制在60km/h(约17m/s)至120km/h(约33m/s),如图3所示,将自然路段BE划分为3个逻辑路段BEa(包括逻辑车道BEa1、BEa2和BEa3)、BEb(包括逻辑车道BEb1、BEb2和BEb3)和BEc(包括逻辑车道BEc1、BEc2和BEc3),其中逻辑路段BEa长度为100m,逻辑路段BEb长度为100m,逻辑路段BEc长度为100m,根据车速限制和天气环境,在BE上前后车间安全距离在50m至100m之间,逻辑路段的划分符合要求,可以理解的,其中BE1、BE2和BE3都是同向的车道。
下面通过管理设备和车辆之间的交互实施例对应用于上述系统构架或场景中的车道调度方法进行说明,实施例中,车辆表示的是车辆侧的应用于车道调度方法的设备,可以是集成于车辆中或者后期安装在车辆上的。
请参阅图4,本发明实施例提供一种车道调度方法,包括:
401、车辆获取预期使用的至少一个逻辑路段,根据逻辑路段生成道路资源分配请求,道路资源分配请求包含至少一个路段标识;
本实施例中,当车辆需要通过行驶的道路上的一个或多个逻辑路段时,车辆获取预期使用的至少一个逻辑路段,根据逻辑路段生成道路资源分配请求,道路资源分配请求包含至少一个路段标识,路段标识用于标识车辆预期使用的逻辑路段,逻辑路段为对车辆行驶道路的逻辑分段,逻辑分段同时将道路包含的车道分段为逻辑车道,逻辑路段包含至少一个逻辑车道,假设车辆需要通过逻辑路段BEa,道路资源分配请求中包含路段标识为BEa。
402、车辆向管理设备发送道路资源分配请求;
本实施例中,由于车辆与管理设备是建立的实时通信连接的,在生成道路资源分配请求后,将其发送至管理设备。
403、管理设备接收车辆发送的道路资源分配请求;
本实施例中,管理设备接收车辆发送的道路资源分配请求,并且在于车辆的通信过程当中,管理设备是知道车辆的标识的,以便反馈响应时能准确的发送至对应的车辆。需要说明的是,按照车辆标识识别车辆只是现有的一种实现方式,在实际的应用中,可能还存在其他方式,此处不做限定。
404、管理设备根据道路资源分配请求为车辆分配道路资源,道路资源分配请求包含至少一个路段标识;
本实施例中,管理设备接收到车辆发送的道路资源分配请求之后,根据道路资源分配请求进行道路资源的分配,道路资源包含与至少一个路段标识对应的至少一条逻辑车道,例如在逻辑路段BEa的逻辑车道BEa1、BEa2和BEa3中选择出逻辑车道BEa1,逻辑车道BEa1就是管理设备分配给车辆通过逻辑路段BEa时使用的逻辑车道。
405、管理设备将至少一条逻辑车道的车道标识发送给车辆;
本实施例中,管理设备根据分配给车辆的至少一条逻辑车道的车道标识发送给车辆,例如将逻辑车道BEa1的车道标识(BEa1)发送至车辆。
406、车辆接收管理设备发送的至少一个车道标识。
本实施例中,车辆接收管理设备发送的至少一个车道标识,按照车辆的设 置,可以将车道标识在车辆的导航设备上显示给用户,或者在用户驾驶车辆时通过语音方式进行播报,或者车辆按照车道标识辅助驾驶或自动驾驶通过车道标识对应的逻辑路段,具体的方式不做限定。
本发明实施例中,管理设备根据车辆发送的道路资源分配请求为车辆分配逻辑车道,并将逻辑车道对应的车道标识发送到车辆,因此,车辆能够根据逻辑车道的车道标识,通过自动驾驶、辅助驾驶或者手动驾驶通过车道标识对应的逻辑车道,与现有技术相比,通过对道路的逻辑路段的划分,管理设备可以为车辆在每个逻辑路段中所要行驶的逻辑车道进行分配,可以实现车辆在道路上的精细化管理,因此,管理设备可以全局的进行道路资源的分配,可以提高道路资源的利用率,调整道路中不同车道上的车辆密度,增强道路上车辆行驶的安全性。
需要说明的是,在本发明优选的方案中,管理设备可以通过在道路资源响应中携带车道标识的方式,反馈道路资源响应给发送道路资源请求的车辆,在实际实施时,还可以通过其他方式,具体不做限定。
可选的,本发明的一些实施例中,管理设备根据道路资源分配请求为车辆分配道路资源,包括:
管理设备解析道路资源分配请求得到路段标识;
管理设备根据路段标识获取路段标识对应的逻辑路段中每一条逻辑车道的车道状态信息,车道状态信息包含空闲状态、占用状态和预留状态;
管理设备根据车道状态信息,确定分配给车辆的逻辑车道。
本发明实施例中,管理设备在接收到道路资源分配请求后,解析道路资源分配请求,得到路段标识,根据路段标识从交通图中找到对应的逻辑路段,并获取该逻辑路段中每一条逻辑车道的车道状态信息,车道状态信息包含空闲状态、占用状态及预留状态等,空闲状况表示的是当前车道中没有车辆行驶,占用状态表示的是当前车道中有车辆行驶,预留状态表示车道已经分配给了其他车辆行驶,根据车道状态信息当前的状态可以确定车辆途径该逻辑路段时行驶哪一条逻辑车道,因此,根据车道状态信息进行道路资源的分配,可以准确的避开逻辑路段中有车辆的逻辑车道,而选择无车辆的空闲逻辑车道,提高了道 路资源的利用率。
可选的,本发明的一些实施例中,管理设备根据道路资源分配请求为车辆分配道路资源之后,还包括:
管理设备将逻辑车道的车道状态信息设置为预留状态;
当车辆驶入逻辑车道时,车辆向管理设备发送的驶入通知;
管理设备根据驶入通知将逻辑车道的车道状态信息设置为占用状态;
当车辆驶出逻辑车道时,车辆向管理设备发送的驶出通知;
管理设备根据驶出通知将逻辑车道的车道状态信息设置为空闲状态。
本发明实施例中,管理设备将道路资源分配响应发送至车辆之后,将分配给该车辆的逻辑车道的车道状态信息设置为预留状态,这里可以理解为从分配这一刻开始,直到接收到该车辆发送的驶入通知,该逻辑车道的预留状态才会改变;当车辆接收到道路资源分配响应,车辆根据响应驶入和驶出逻辑车道时,车辆会发送驶入和驶出通知,管理设备根据通知对逻辑车道的车道状态信息进行更新,有利于管理设备掌握道路中所有逻辑车道的情况,从而更准确的进行道路资源的分配。
上述实施例涉及到的给车辆分配的道路资源,是没有道路资源使用时间的,这样对道路上车辆的精细化管理是不够的,下面对道路资源分配请求还包含路段使用时间及道路资源还包含车道使用时间的情况进行说明。
请参阅图5,本发明实施例提供一种车道调度方法,包括:
501、车辆获取预期使用的至少一个逻辑路段,根据逻辑路段生成道路资源分配请求,道路资源分配请求包含至少一个路段标识及路段使用时间;
本实施例中,当车辆需要通过行驶的道路上的一个或多个逻辑路段时,车辆获取预期使用的逻辑路段,并且还根据车辆当前的位置及车速等条件值,计算得到预期通过该逻辑路段的路段使用时间,根据逻辑路段和路段使用时间生成道路资源分配请求,道路资源分配请求包含路段标识和路段使用时间,假设车辆需要在1点至1点零5秒通过逻辑路段BEa,道路资源分配请求中包含路段标识为BEa,路段使用时间为1点至1点零5秒。
502、车辆向管理设备发送道路资源分配请求;
详情请参考步骤402。
503、管理设备接收车辆发送的道路资源分配请求;
详情请参考步骤403。
504、管理设备解析道路资源分配请求得到至少一个路段标识及路段使用时间;
本实施例中,管理设备解析道路资源分配请求,得到得到至少一个路段标识(例如BEa)及与路段标识对应的路段使用时间(例如1点至1点零5秒)。
505、管理设备根据路段标识及路段使用时间获取路段标识对应的逻辑路段中每一条逻辑车道在路段使用时间内的车道状态信息;
本实施例中,根据路段标识及路段使用时间获取路段标识对应的逻辑路段中每一条逻辑车道在路段使用时间内的车道状态信息,车道状态信息包含空闲状态、占用状态和预留状态,假设在1点至1点零5秒内,逻辑车道BEa1未被管理设备分配给其他车辆,并且在BEa1上没有车辆,则为空闲状态;逻辑车道BEa2上有车辆行驶为占用状态,逻辑车道BEa3在1点至1点零5秒分配给了其他车辆,为预留状态。
506、管理设备根据车道状态信息,确定分配给车辆的至少一个逻辑车道及车道使用时间;
本实施例中,根据上述假设得到的车道状态信息,逻辑车道BEa1为空闲状态、逻辑车道BEa2为占用状态及逻辑车道BEa3为预留状态,确定分配给车辆的逻辑车道为BEa1及车道使用时间为1点至1点零5秒,如果车道状态信息为逻辑车道BEa1在1点至1点零3秒是占用状态,逻辑车道BEa2在1点至1点零5秒是占用状态,逻辑车道BEa3为预留状态,那么根据最优选择方案,应当分配的逻辑车道为BEa1及车道使用时间1点零3秒至1点零8秒。
507、管理设备将至少一个逻辑车道的车道标识及车道使用时间发送至车辆;
本实施例中,管理设备将至少一个逻辑车道的车道标识及车道使用时间发送至车辆,例如管理设备将步骤506中得到的逻辑车道的车道标识(BEa1)和车道使用时间(1点零3秒至1点零8秒)发送至与道路资源分配请求对应的车辆。
508、车辆接收管理设备发送的至少一个车道标识及车道使用时间。
本实施例中,车辆接收到管理设备发送的至少一个车道标识及车道使用时间,例如车道标识(BEa1)和车道使用时间(1点零3秒至1点零8秒),车辆的导航设备能够在交通图中找到BEa1对应的逻辑车道,并且将车道使用时间显示出来,或者按照车道使用时间自动驾驶通过BEa1对应的逻辑车道,具体的方式不做限定。
本发明实施例中,管理设备分配的道路资源,是精确到了逻辑路段中的一条逻辑车道,以及车辆通过这条逻辑车道的车道使用时间,这样精确到车道和行驶时间的道路资源分配,更加有利于道路上车辆的精细化管理。
上述实施例对管理设备分配道路资源步骤的细化时,逻辑路段中车道状态信息是进行道路资源分配的关键,下面对管理设备是如何及时更新各逻辑车道的车道状态信息进行说明。
可选的,本发明的一些实施例中,管理设备将道路资源分配响应发送至车辆设备之后,还包括:
管理设备将逻辑车道在车道使用时间内的车道状态信息设置为预留状态;
当车辆进入逻辑车道时,车辆向管理设备发送驶入通知;
管理设备接收车辆发送的驶入通知;
管理设备根据驶入通知将逻辑车道在车道使用时间的剩余时间部分内的车道状态信息设置为占用状态;
当车辆驶出逻辑车道时,车辆向管理设备发送驶出通知;
管理设备接收车辆发送的驶出通知;
管理设备根据驶出通知将逻辑车道在车道使用时间的剩余时间部分内的车道状态信息设置为空闲状态。
管理设备将道路资源分配响应发送至车辆之后,将车道使用时间内逻辑车道的车道状态信息设置为预留状态,这样在其他车辆有同样的请求时,不会分配相同的逻辑车道,以免两台车辆同时驶入同一条逻辑车道,导致安全事故;当车辆驶入和驶出逻辑车道时,车辆会发送驶入和驶出通知,管理设备根据通知对逻辑车道的车道状态信息更新,有利于管理设备实时的掌握所有整个道路 的情况,从而更准确的进行道路资源的分配。
可选的,本发明的一些实施例中,车道调度方法还包括:
当车辆未在车道使用时间内驶入逻辑车道时,管理设备获取逻辑路段的新的车道状态信息;
管理设备根据新的车道状态信息为车辆分配新的道路资源,并根据新的道路资源生成第一道路资源更新通知,第一道路资源更新通知包含更新的车道标识及更新的车道使用时间,更新的车道标识用于标识管理设备为车辆更新的逻辑车道,更新的车道使用时间表示车辆使用更新的逻辑车道的时间;
管理设备向车辆发送第一道路资源更新通知;
车辆接收管理设备发送的第一道路资源更新通知。
本发明实施例中,当车辆在车道使用时间内未驶入逻辑车道时,即表示车辆可能未按照管理设备反馈的道路资源分配响应行驶,例如,车辆在该逻辑车道之前进行了减速行驶,导致未能在车道使用时间内驶入该逻辑车道,需要根据新的车道状态信息重新为车辆分配新的道路资源,生成第一道路资源更新通知,并将第一道路资源更新通知发送至车辆,使得车辆接收到第一道路资源更新通知后,可以顺利的通过逻辑路段,以满足车辆对于道路资源的需求。
可选的,本发明的一些实施例中,车道调度方法还包括:
当车辆未在车道使用时间内驶出逻辑车道时,管理设备增加车道使用时间的时长,并生成第二道路资源更新通知;
管理设备向车辆发送第二道路资源更新通知,第二道路资源更新通知包含更新的车道使用时间,更新的车道使用时间表示更新后车辆使用逻辑车道的时间
车辆接收管理设备发送的第二道路资源更新通知。
本发明实施例中,如果车辆按照道路资源分配响应驶入逻辑车道,但是车辆发生了故障,使得车辆停止或者减速,那么车辆在车道使用时间内无法驶出逻辑车道,管理设备对该车辆使用该逻辑车道的车道使用时间进行增加,生成第二道路资源更新通知,并向车辆发送第二道路资源更新通知,使得车辆可以按照第二道路资源更新通知通过逻辑路段,提高了管理设备在车道调度过程中 的灵活性。
需要说明的是,当车辆是由于车速减慢,未在车道使用时间内驶出逻辑车道时,如果该车辆之后的车辆的驶入时间点是紧接该车辆驶出时间点,则管理设备需要向该车辆之后的车辆发送提示信息,使得车辆有减速或停车等操作的反应时间,避免发生追尾。
可选的,本发明的一些实施例中,车道调度方法还包括:
当逻辑车道在车道使用时间前预留状态发生变化时,管理设备获取逻辑路段的新的车道状态信息;
管理设备根据新的车道状态信息为车辆分配新的道路资源,并根据新的道路资源生成第三道路资源更新通知,第三道路资源更新通知包含更新的车道标识及更新的车道使用时间,更新的车道标识用于标识管理设备为车辆更新的逻辑车道,更新的车道使用时间表示车辆使用更新的逻辑车道的时间;
管理设备向车辆发送第三道路资源更新通知;
车辆接收管理设备发送的第三道路资源更新通知。
本发明实施例中,当在车道使用时间前,逻辑车道的预留状态发生变化,例如,车道使用时间的驶入时间点为1点,在0点50分逻辑车道上发生车辆故障,车辆维修人员上报维修时间是0点55分至2点整,那么车道使用时间是包含在维修时间内的,那么在车道使用时间内逻辑车道必然无法行驶车辆,将逻辑车道在车道使用时间内的预留状态改设为占用状态,对分配给车辆的逻辑车道及车道使用时间进行更新,生成第三道路资源更新通知,将第三道路资源更新通知发送至该车辆,使得车辆可以避开原来分配的逻辑车道,改行其他逻辑车道顺利通过逻辑路段,提高了安全性。
可选的,本发明的一些实施例中,
管理设备与车辆保持逻辑路段及逻辑车道的信息的同步,逻辑路段和逻辑车道的信息包括逻辑路段的路段标识、逻辑车道的车道标识、逻辑路段对应的道路分段及逻辑车道对应的车道分段。
本发明实施例中,如果道路进行了重新施工,导致逻辑路段和逻辑车道的信息的变化,例如,对逻辑路段BEa中的逻辑车道的车道标识进行了重新编号, 将原来的BEa1变为BEa3,BEa3变为BEa1那么将导致管理设备的交通图是会改变的,而车辆是需要与管理设备上的交通图保持一致性,管理设备才能准确的为车辆分配需求的道路资源。
需要说明的是,管理设备可以根据车流量或道路情况等条件来调整逻辑路段的长度,以道路情况为例,例如在晴朗天气下,道路情况良好的高速上的前后车间行驶安全距离为50m左右,逻辑路段的长度调整为60m,在雨雪大风等天气环境下,道路情况复杂的高速上的前后车间行驶安全距离为100m左右,逻辑路段的长度自动调整到100m,逻辑路段的长度不小于前后车间行驶安全距离,管理设备根据逻辑路段的长度更新逻辑路段的逻辑车道信息,在具体实施的过程中,得出的理论是,逻辑路段的长度越接近与前后车间行驶安全距离,越能提高道路资源利用率。
需要说明的是,如果车辆需要通过自然路段BE,那么预期使用的逻辑路段是BEa、BEb和BEc,假设车辆需要管理设备一次性的分配所有逻辑路段的道路资源,那么道路资源分配请求中包含路段标识是一个标识序列,按照先后顺序依次为BEa-BEb-BEc,路段使用时间为与路段标识序列对应的路段使用时间序列或车辆驶经逻辑路段的总时间,路段使用时间可以表示为路段使用时间序列1:00:00-1:00:05-1:00:10-1:00:15或者总时间1点整至1点15分,同理,车道标识和车段使用时间也可以如此表示。
需要说明的是,路段使用时间包括驶入逻辑路段的驶入时间点和驶出逻辑路段的驶出时间点、或驶入逻辑路段的驶入时间点及驶经逻辑路段的时长、或驶出逻辑路段的驶出时间点及驶经逻辑路段的时长,即通过逻辑路段BEa的路段使用时间可以用驶入时间点1点整和驶出时间点1点零5秒表示,也可以用驶入时间点1点整和驶经BEa的时长5秒表示,还可以用驶出时间点1点零5秒和驶经BEa的时长5秒表示,同理,车道使用时间也可以同路段使用时间一样的表达方式。
需要说明的是,在逻辑路段为两个以上时,道路资源分配请求中的每一个路段标识都需要在道路资源分配响应中有一个对应的车道标识,这样车辆才能顺利通过,车道标识序列中,相邻两个车道标识可以是在一个自然车道,或者 在邻道的自然车道,例如,为车辆分配的逻辑车道是BEa1和BEb2,车辆从自然车道BE1变道至BE2是可行的;但是如果为车辆分配的逻辑车道是BEa1和BEb3,车辆需要在驶出BEa1时,从自然车道BE1变道至BE3,跨越一个车道是比较危险的,是不被允许的,管理设备分配道路资源时需要自动排除。
