Embodiment 1

[0023] refer to Figure 1 ~ Figure 3 , a method for sharing resources of public transport dedicated lanes that guarantees BRT priority. Under the premise of ensuring BRT priority, ordinary bus vehicles can enter the BRT dedicated lanes according to the following control rules: (1), ordinary buses borrow BRT vehicle dedicated lanes Control process: According to the geographic location information, calculate the distance between the ordinary bus on the non-BRT vehicle-only lane and the BRT vehicle, and record it as d, and set the minimum value as d borrow , when d≥d borrow When it is determined that borrowing is allowed, the ordinary bus is free to choose whether to enter the dedicated lane, otherwise ordinary buses are not allowed to enter the dedicated lane; Vehicle distance D is less than the minimum safety distance d save , to send a returning control instruction to the ordinary bus in front of the BRT vehicle, and the ordinary bus vehicle will drive out of the BRT vehicle...

Embodiment 2

[0025] A public transport lane resource sharing system that guarantees the priority of bus rapid transit, including installing vehicle positioning equipment, wireless network adapters and external antennas on ordinary bus vehicles and BRT vehicles, and arranging network access points on the dedicated lanes of BRT vehicles, said The wireless network adapter and the external antenna are wirelessly connected to the network access point, the vehicle positioning device is wirelessly connected to the bus information processing center, and each network access point is connected to the bus information processing center; the bus information processing Center includes:

[0026] A wireless local area network controller is used to form a wireless local area network for each vehicle positioning device and network access point;

[0027] The database server is used to store the geographical location information and real-time data of the lanes and the historical data of the lanes and buses se...

Abstract

The invention discloses a public transit exclusive lane resource sharing method and a resource sharing system for guaranteeing bus rapid transit (BRT) priority. On the premise of guaranteeing the BRT priority, a common transit bus can enter a BRT bus exclusive lane to run according to the following control rules: (1) a control flow that the common transit bus borrows the BRT bus exclusive lane: calculating a distance between the common transit bus on a non-BRT bus exclusive lane and a BRT bus and marking the distance as d according to geographic location information, setting a minimum value as d borrow, when d is more than or equal to d borrow, determining that the common transit bus is allowed to borrow the BRT bus exclusive lane and enabling the common transit bus to freely select whether to enter the exclusive lane or not, otherwise preventing the common transit bus from entering the exclusive lane; and (2) a control flow that the common transit bus returns the lane after borrowing the BRT bus exclusive lane: sending a lane-returning control instruction to the common transit bus in front of the BRT bus when the distance D between the common transit bus and the BRT bus is less than the minimum safe distance d save, and making the common transit bus to pull out from the BRT bus exclusive lane in set time T. The method and the system effectively improve the utilization ratios of bus lanes.

Description

technical field [0001] The invention relates to an intelligent traffic control method, in particular to a method and system for sharing resources of lanes dedicated to public traffic. Background technique [0002] In recent years, in order to effectively alleviate traffic congestion and save energy, more and more cities have implemented a bus priority strategy in their transportation policies and vigorously promoted bus rapid transit (BRT). Dedicated lanes for public transport are an important part of the bus priority method and the most basic element to ensure bus priority and rapid passage. However, there are generally only two methods for utilizing the resources of public transport lanes in our country: ① Only BRT and ordinary buses can run on the public transport lanes throughout the day or during the peak hours of the day; ②Some public transport lanes only allow BRT is used, and other ordinary buses cannot enter. [0003] There are obvious deficiencies in the above tw...
