Abstract

An urban road network structure unit with no traffic lights comprises local grid-like road network units which form a vehicle road network, in which, traffic lights of all vehicle road crossings of the unit are cancelled, the structure forms of the unit are different grid forms or a combination thereof, four crossings at the corners of each unit are interchange crossings, and the remainders are level crossings with no conflict points or interchange crossings. At the interchange crossing, a separate type flyover bridge is arranged, with center isolate strips being provided in the middle of the roads. Partition guardrails are provided longitudinally on either side of the roads, along which exits or entrances are arranged at required intervals. Pedestrian bridges or pedestrian underpasses are arranged across the vehicle road.

Description

Urban road network structure unit for canceling signal lights

(1) Technical field

The invention relates to a road network unit of an urban road network, in particular to a square format road network structure of a city motor vehicle road network.

(2) Background technology

With the rapid increase in the number of cars, traffic jams frequently occur in existing urban motor vehicle road networks. The existing urban motor vehicle road network consists of four-level roads, which are express roads, trunk roads, secondary trunk roads, and branch roads. Most of the intersections in the road network unit are intersections with conflicting points, which are generally managed by signal lights. In this kind of road network, the motor vehicle is commanded by the signal light at the intersection and needs to be stopped frequently. The traffic is often detoured in the blocked road section, which greatly reduces the traffic capacity of the motor vehicle, and the travel time and travel distance of the motor vehicle are greatly extended. The zero value idling that occurs in the motor car consumes a lot of fuel. It not only causes serious energy waste, but also restricts the development of the automobile industry. In severe cases, it will also affect the operation of urban functions.

According to the existing technology, the way to improve road capacity in cities usually involves occupying a large amount of land to build large overpasses, constructing elevated roads, increasing expressways, forming a low-density urban expansion, and a phenomenon of “spreading large cakes” in urban areas. However, in the reconstruction of existing urban roads, these methods are often limited by land, space and investment. It is impossible to adopt them in large quantities. Even if they are adopted, they will often induce new traffic volume and cause new traffic congestion. More and more repairs, the car is getting blocked, and it is impossible to jump out of the "congestion - governance - re-congestion" cycle. There are various solutions to solve the traffic congestion in the city. There are widespread problems in implementation or difficulties in the fundamental solution to the urban road network. These key issues are: 1. Urban road network. The contradiction between the characteristics of intermittent traffic modes and the characteristics of high-speed continuous operation of vehicles; Second, the space for high-speed operation of motor vehicles is mixed with the safe operation space of people; Car traffic, and completely eliminate traffic congestion, the two can not take into account.

By adopting the invention, the vehicle can continuously drive due to no signal light and traffic jam, which can save nearly half of the fuel of the automobile and shorten the travel distance, and the vehicle fuel consumption can be reduced by about one quarter of the original; The travel distance is shortened, which can shorten the travel time by about a quarter. By adopting the invention, the signal light of the motor vehicle road can be cancelled, so that the motor vehicle can continuously run without stopping, and the problem of shortening the travel time, saving the traffic energy consumption and reducing the pollution of the exhaust gas can be achieved. By adopting the road network unit structure to reconstruct the existing urban road network, it is easy to implement the investment with less efficiency and quicker, and the signal light on the urban road can be cancelled in a short time to realize the rapid operation of the motor vehicle. The network unit can form a fast road network for continuous driving of the motor vehicle. The motor vehicle does not need to stop at the intersection, the road traffic capacity is greatly improved, the traffic congestion of the city is completely eliminated, and the separation of people and vehicles is solved at the same time. The space for man and vehicle operation is independent and safe, and the city is avoided. Traffic jam problem. The invention has important significance for the existing urban road traffic reconstruction, and is beneficial to saving a large amount of road investment for the country, saving a large amount of non-renewable energy, and establishing a conservation-oriented society. It is especially suitable for the construction of motor vehicle networks in new cities or urban new areas.
