Detailed Description

In order to explain technical contents, structural features, implementation principles, and objects and effects of the present invention in detail, the following detailed description is given with reference to the accompanying drawings in combination with the embodiments.

As shown in fig. 1 and 2, the present invention discloses an embodiment of a method for rights-based navigation.

Fig. 1 is a simplified road network diagram, and a road network in reality may include more road topology structures than the road network diagram. The vehicle taken by the passenger is currently located at the departure place 1, and the departure place 1 is not limited to a specific location, which is only for convenience of describing the embodiment, and the departure place may be at any stop point of the road network for getting on or off the vehicle. The road network can be divided into

road segments

3, 4, 5, 6 and 8, the segments of the road network can be one road segment according to the line segments between the nodes in the topological graph, or can be divided into a plurality of road segments, such as the road segment 3, for the line segments between the nodes in the topological graph, because of the midway parking station 7, the road segment 3 can be divided into two sections by the midway parking station 7. The road network may have overpasses (not shown). The road section can only mark an independent lane, is suitable for rail cars, can also mark a plurality of parallel lanes, and is suitable for multi-lane road surfaces and roads. The track destination 2 is an address to which a passenger subscribes, the intermediate stop 7 is an auxiliary facility of a road network, and the intermediate stop 7 may be booked as a destination in the same way.

FIG. 2 is a step of a privilege-based navigation method.

In step S1, the road network data and the passenger data are registered in the network side device. The network side equipment comprises at least one server, records road section authority of each road section in the road network in each time period, records and verifies the passing authority, and plans the navigation guidance. Based on the known technology of the internet, the network side device has a structure including, but not limited to, a server, a communication network, and the like, the geographic location of the network side device is not limited to one point, but may be respectively set in different areas, and the functions of the present invention can be realized as long as the communication network can exchange transmission data in time. The road network data comprises road section authorities of road sections in the road network, and the passenger data comprises an identification code and a passing authority. The road section authority comprises entrance guard authority, the passing authority comprises entrance authority, and vehicles with the entrance guard authority not conforming to the entrance guard authority are prohibited from entering the road section. The access control authority comprises role authority and personal authority; the role authority forbids vehicles except the role set by the access authority to enter the road section; wherein the personal authority prohibits vehicles with non-conforming identification characteristics or passwords from entering the road segment. In fig. 1, the access control authority can be set in the section 8, and only vehicles matched with the corresponding access control authority can enter the entrance control authority. The embodiment of the invention is applied to an air rail transit system, all vehicles are automatically driven, and whether the vehicles can enter the road section 8 or not is identified in advance when the vehicles start to request navigation guidance from the departure place 1, so that the vehicles which do not obtain the passing right are prevented from being blocked at the entrance of the road section 8, the travel waste is caused, the vehicles can not advance and retreat, and the traffic jam is caused at the entrance of the road section 8. The road section authority further comprises a saturation authority, the passing authority comprises a priority authority, vehicles with the priority authority larger than the saturation authority are allowed to enter the road section, and the saturation authority is set based on saturation obtained by dividing the statistical traffic flow of the road section in the preset time period by the maximum allowed traffic flow. When the saturation authority is over saturated, the vehicles are transferred to other road sections from small to large with priority authority.

For each road section, the traffic flow has a maximum allowable value, which depends on the speed of the traffic flow and the density of the traffic flow (the safety interval of the vehicle), if the traffic flow exceeds the maximum allowable value, the vehicle is either over-speed or the safety interval of the vehicle is insufficient, which easily causes traffic accidents, on one hand, the traffic accidents can be casualties and the vehicles are damaged, on the other hand, the traffic interruption can be caused, and the speed is not reached. The road network is maintained to be close to a saturated state and runs at a limited speed, so that the maximum transport capacity can be obtained, traffic infrastructure can exert the maximum value, passengers can quickly arrive at a destination, the traffic time is shortened, and the social benefit of the whole road network area is improved. The method has the advantages that privileged vehicles such as police cars and emergency vehicles such as ambulances cannot arrive at a destination in the shortest possible time under the condition that traffic flows in a road network are saturated and even blocked, a certain amount of traffic flow margin is reserved for the possible emergency vehicles, and the improvement of the overall social benefit is realized. Although most passengers wish to shorten the travel time, it may be true that each passenger may not have consistent speed sensitivity at different times, some passengers may have significant losses if they cannot arrive at the destination according to the scheduled time, such as missing the takeoff time of an airplane, and another part of passengers may not have much loss even after the time delay of arriving at the destination, such as tourists taking a vehicle for urban sightseeing. We do not discuss social and economic issues, but rather, the objective existence of these issues, requiring technical support to be solved, and thus creating value. In fact, in a freely open road network, such as the existing road traffic, the driving route of vehicles is determined by individuals, when a vacancy is found on a road, the vehicles can meet the gap and contact pins, and the final result is that too many vehicles enter some road sections to cause congestion. The technical scheme provided by the invention comprises the steps that saturation authority is registered for each road section, when all vehicles in a road network are driven by unified navigation scheduling, all vehicles drive according to a preset route and each road section according to a preset speed, the number of the vehicles driven by each road section is predicted at a foreseeable time point, and a quotient value, namely saturation, can be obtained by dividing the predicted number by the maximum traffic flow number. The saturation is in change at different time instants for different road segments.

In step S2, the navigation terminal sends a navigation request to the network-side device, where the navigation request includes a departure location, a destination, and an identification code; the navigation request may further include a preset approach road segment, an avoidance road segment, or a mid-way stop, a preset departure time, or an arrival time. The navigation terminal runs with an electronic navigation map, the electronic navigation map has a man-machine interaction interface, and the man-machine interaction interface comprises: an input control, a send control, and a navigation interface. The navigation terminal can be a private mobile phone of a passenger, a navigation APP is installed on the mobile phone, and the mobile phone can serve as the navigation terminal to realize the function of the navigation terminal. The navigation terminal can also be physically connected with a vehicle-mounted navigation terminal on the vehicle through a wire, and even fixedly installed to form a component part of the vehicle. The private mobile phone scheme has the advantages that the navigation can be set and information can be sent and received before passengers enter the vehicle, wherein the information comprises navigation requests, navigation guidance and the like; the identity recognition module on the mobile phone can be used for quickly sending the identity recognition code; passenger data can be preset to realize personal preference setting; the vehicle-mounted navigation terminal can be prevented from being touched, and the risk of disease transmission and the like can be reduced. The vehicle-mounted navigation terminal is directly connected with the running control equipment of the vehicle, when the vehicle is associated with a passenger, the vehicle is reserved by the passenger, and the mobile phone navigation terminal of the passenger exchanges data with the navigation terminal of the vehicle to realize a synchronization function.

In step S3, the network-side device plans a navigation guidance according to the navigation request, where the navigation guidance includes retrieving its passing authority according to the id code, selecting a group of sequentially-connected traveling segments from the segments whose passing authority matches the segment authority, and passing through a predetermined time period of each of the traveling segments; after the navigation terminal sends a navigation request to the network side equipment, a passenger selects or the network side equipment recommends a vehicle, the navigation terminal is associated with the vehicle side equipment, and the navigation vehicle arrives at a departure place at the preset time. The navigation guidance planning process is described with reference to fig. 1, through retrieval combination, 3 alternative paths from a departure place 1 to a destination 2 are provided, a road section 8 is provided with access control authority, the access control authority can be set by a right owner of the destination, if the access control authority is set as role authority, the role definition only allows a company employee to enter, only the role identity is retrieved through a passenger identity code, it is confirmed that a vehicle matched with the corresponding access control authority by the company employee can enter, otherwise, the road section 8 is not planned to be a part of the navigation guidance. The entrance guard authority can also be set as personal authority by the owner of the destination, the personal identification code which meets the condition is compared with the identification code or the password, and the non-conforming vehicle is forbidden to enter the road section. The priority of the common passenger is preset to be 90 percent and is less than the saturation limit of 95 percent (saturation) of the road section 3 in the current time period, the road section 3 is not selected, the road section 6, the road section 5 and the road section 8 form a group of paths which are sequentially connected in series in space and time, and when the priority and the saturation limit are checked one by one and meet the conditions, the paths form a navigation guide. If the vehicle belongs to a special vehicle for executing an emergency task, the priority authority of the vehicle is preset to be 97% larger than 95% of the saturation authority of the road section 3 in the current time period, and then the road section 3 belongs to the alternative road section.

In step S4, the network-side device transmits the navigation guidance to the navigation terminal and the vehicle-side device associated with the navigation terminal, and the vehicle travels in accordance with the navigation guidance. The vehicle runs along the road section 6, the road section 5 and the road section 8 according to the navigation guidance, when the vehicle runs on the road section 6, if the saturation authority change of the road section 5 is 100% of the event, in order to ensure smooth driving safety, the vehicle running on the road section 5 in the preset time period has part of the modified navigation guidance and changes to the running road section 4. The saturation permission change of 100% may include temporary entering of an emergency vehicle, or a change in road conditions of a road, such as a requirement of reducing a maximum allowable value of traffic flow in the case of strong wind and heavy rain.

The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the present invention, which is therefore intended to cover all equivalent changes and modifications within the scope of the present invention.
