Embodiment 1

[0214] The simulation example uses Veins, an open source IoV simulation framework bidirectionally coupled by the wireless network simulator OMNET++ and the microscopic traffic simulator SUMO (Simulation of Urban Mobility). The simulation content is mainly the speed guidance of signalized intersections, so that vehicles can pass through the intersection without stopping.

[0215] The traffic scene is a two-way 6-lane intersection with a speed limit of I v =[20,60](km / h), the simulation communication adopts the IEEE802.11p wireless communication standard dedicated to the Internet of Vehicles, and the specific traffic simulation scenarios are as follows Figure 8 As shown, the parameters are shown in Table 3.

[0216] table 3:

[0217]

[0218] The network communication mainly adopts the network simulation model based on the vehicle mobile ad hoc network (VANET), which can accurately simulate the network communication scenarios of the Internet of Vehicles, such as Figure 9 ...

Abstract

The invention relates to a signalized intersection vehicle speed guiding system based on Internet of Vehicles, which is characterized by comprising a signal acquisition module, a wireless transmissionmodule, a signal processing module and a multimedia video / voice broadcasting module. A guiding lane suggestion module is used for judging the driving direction of a vehicle at an intersection according to stored driving information of the vehicle, specifying a target lane, suggesting that the vehicle is changed to the target lane, and then entering the acceleration / braking suggestion module; theacceleration / braking suggestion module is used for establishing a reference movement model according to the stored road information of the driving road section, the state information of a signal control machine, the driving information of the vehicle and the processed traffic information, and utilizing the DC-GLOSA algorithm to select the acceleration of the vehicle at the moment to determine an instant acceleration / braking strategy. According to the invention, the operation complexity of a driver is reduced, the number of times to stop at a signalized intersection is reduced, and the drivingcomfort is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a vehicle speed guidance system and method at a signalized intersection based on the Internet of Vehicles. Background technique [0002] In the urban road driving environment, since the driver cannot predict the real-time changes of the signal lights at the intersection ahead, he can only choose to drive blindly, which may lead to improper speed control and increase the number of unnecessary stops, which means more traffic congestion. A large amount of fuel waste can even cause traffic accidents. [0003] To solve this problem, there are currently two main methods, one is to optimize the green light allocation time based on the traffic light control technology based on adaptive traffic flow, and the other is the speed guidance technology at intersections under the Internet of Vehicles environment (GLOSA, Green Light Optimal Speed ​​Advisory). The ...
