Embodiment Construction

[0087] Build a real-time traffic road network model, such as Figure 5 The simulated road network shown. The order of numbers on the side of the figure is road section number, length (unit: km), and traffic capacity (unit: veh / h).

[0088] According to the travel purpose of the vehicle, all feasible routes are calculated from the starting point number 1 to the ending point number 15. As shown in Table 1.

[0089] Table 1 Full Feasible Path

[0090]

[0091]

[0092]Taking the route number 10 as an example, the route passes through 1-2-5-8-11-12-15, and the road section number is 1-4-9-14-17-20, among which there are Signal light, assuming that the current moment d=0, the cycle of signal light is 65s (green light 35s, red light 30s), 90s (green light 50s, red light 40s), 70s (green light 35s, red light 35s) and 100s (green light 60s, red light 35s) and 100s (green light 60s, red light 40s), the phase difference of each signal light is 0s, and the average passing time ...

Abstract

The invention discloses an energy-saving real-time dynamic route planning method applicable to an intelligent networked automobile. The energy-saving real-time dynamic route planning method specifically comprises the following steps: establishing a three-dimensional road network model considering time dimension; acquiring the state of signal lamps at the tail end of each road section; searching all feasible routes in a road network by virtue of a full-feasible path search algorithm according to a starting point and a destination; according to traffic flow information, computing the shortest transit time and calculating the theoretical transit time on the road section; recommending a route with the shortest transit time as a real-time dynamic route; and considering an automobile potion change factor during the driving of an automobile, re-invoking a dynamic route planning algorithm while entering an effective range of the tail end of the road section, and further updating the optimal real-time dynamic route of the current automobile. The energy-saving real-time dynamic route planning method has the advantages that a trip route with the shortest full-process theoretical transit time in a three-dimensional space-time network can be searched; and the driving energy consumption of the automobile can be remarkably reduced, and the aim of energy-saving tripping is achieved.
