Background technology
On the current market popular Vehicular navigation system be mostly map of navigation electronic just in local on-board system of navigation (terminal) system, its utonomous working does not need the support of infrastructure (like communication network).The on-board navigational system is when the path computing in road net of carrying out from the starting point to the destination; Only consider respectively that the requirement of system separately carries out guidance path independently with option and calculate, generally do not consider when with the pairing vehicle arrival of navigational system path in have the also arrival simultaneously or using the situation in this highway section of how many other vehicles during certain road segment segment.As if having too much vehicle to arrive simultaneously or using this highway section simultaneously, will cause and block up, thereby influence traffic.
Summary of the invention
It is a kind of through taking all factors into consideration the result of each vehicle on-board navigational system path computing that the object of the invention is to provide, and plans as a whole to distribute public road net to carry out the Vehicular navigation system that path planning is optimized again.
The present invention includes some on-board automobile navigation terminals and a computing center, each said on-board automobile navigation terminal is connected with said computing center wireless data respectively; Each on-board automobile navigation terminal has to computing center sends the device that calculates the good guidance path in road net from the starting point to the destination, also has the guidance path result's whether ratifying of receiving that computing center provides calculated at corresponding on-board automobile navigation terminal device; Computing center has the device of reception from the guidance path in road net from the starting point to the destination at each on-board automobile navigation terminal; The analytical equipment that also has same road segment in the guidance path that possibly travel at each on-board automobile navigation terminal; Having possibility travels into the priority level ordering analytical equipment of the different on-board automobile navigations terminal vehicle of same road segment; Has analytical equipment to each highway section identical travel direction possibility loading condition; Has the analytical equipment that whether allows to get into this highway section according to each highway section possibility loading condition and each terminal of priority level analysis of different on-board automobile navigations terminal vehicle; Has the device that sends the guidance path result who whether ratifies to be calculated at corresponding on-board automobile navigation terminal to each on-board automobile navigation terminal.
What the present invention introduced the identical travel direction of road segment segment can portative notion: certain highway section (direction) goes up at sometime possible vehicle fleet size and is called the possible load of this highway section (direction) in this moment in the map of navigation electronic.If certain highway section is a two way, then two directions being calculated respectively or predicted maybe load.
The present invention introduces the notion of the load capacity of road segment segment direction: the load capacity of certain highway section direction is meant under this load in the map of navigation electronic, and wagon flow is significantly less than speed design or the speed limitation board regulation possibly, i.e. traffic congestion will form.Load capacity can be according to road section length, number of track-lines, have a lot of social connections, allow the vehicle class that travels, speed design or the speed limitation board regulation to estimate.If the historical data of the transport information in this highway section is arranged, also these data can be incorporated in the estimation, and give higher weight.
The load capacity of certain road segment segment direction can artificially be adjusted around its estimated value as required.As under extreme case, can turn down is zero, promptly seals this road segment segment direction.The another one example is load capacity to be made as be higher than its estimated value, this means to allow more vehicle to get into this road segment segment, and its cost is this road segment segment of tolerance blocking up to a certain degree.
More than about the road segment segment direction maybe load and the notion of load capacity can further refine to the track level.Like this, can obtain the possible load and the load capacity in certain variant track of road segment segment direction.
The present invention introduces the notion of the priority level of guidance path computation requests: the priority of guidance path computation requests can be divided (being better than truck like car) by the classification of vehicle; Also can be by other principles: as by what are paid; Also can divide by function (being better than public vehicles) like bus; Also can divide (being better than nonlocal car) by the region like local car.Traffic police, fire truck and ambulance have the highest priority.
When Real-time Traffic Information can utilize, can combine Real-time Traffic Information to carry out above-mentioned path computing.
The present invention considers the path computing result who is installed in the terminal on the vehicle that respectively has on-board automobile navigation terminal as a whole; Planning as a whole to distribute public road net to carry out path planning optimizes again; To reach when making each relevant terminal obtain its driving path that needs, avoid the formation of blocking up.In the ideal case, traffic congestion can not form again.The present invention also introduces the notion of the priority level of path computing request, ensures that the high vehicle of priority preferentially uses the purpose of road network thereby reach.
Embodiment
An on-board automobile navigation terminal (vehicle mobile terminals) is installed respectively on each vehicle, and computing center is arranged on network-side as in road control center.Each terminal adopts the wireless network data signal to be connected with computing center respectively.
