Description

Road traffic jam control method

Technical Field

The invention relates to the technical field of traffic management, in particular to a road traffic jam control method.

Background

Urban traffic is a link and a life pulse of urban social activities and economic activities, and plays an extremely important role in urban economic development and improvement of living standard of people. In recent years, the urbanization process of China is accelerated, the number of motor vehicles is increased dramatically, and the increase speed of urban road construction cannot keep up with the increase speed of traffic volume. Serious traffic congestion and congestion phenomena occur in many large and medium cities in China, and the life of people is seriously hindered. Many methods and measures have been taken for this in various places: traffic police's command on the way is increased, electronic monitoring management, radio broadcasting road conditions information etc. these measures have alleviated traffic pressure to a certain extent, but the traffic congestion phenomenon still takes place.

The conditions constituting traffic congestion are diverse and include normal factors and abnormal factors. Normal factors such as too many vehicles, a large number of vehicles in a short time, and the ability to go far away from the road cause the efficiency of the road to be affected. An abnormal factor is, for example, occupation of a lane caused by a temporary vehicle collision. In addition, when the vehicle stops at a traffic light, the red light is switched to the green light, so that the driver usually has an operation response time of about two seconds, the driver does not feel waste of time under the condition of no traffic jam, and the operation response time is important when the number of vehicles is large. Particularly, in urban roads, more crossroads exist, a traffic light may exist at intervals of hundreds of meters, automobiles are in a stop state for most of time, and the overall traffic rate of the automobiles is low.

Detailed Description

For further understanding of the features and technical means of the present invention, as well as the specific objects and functions attained by the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description.

As shown in fig. 1, the present invention discloses a road traffic jam control method, which comprises the following steps:

the method comprises the steps of selecting a road 1 intersection with a digital indicator light, wherein the intersection is provided with a vehicle forbidden line 2, the digital indicator light represents a traffic light with digital display, red numbers are displayed when the red light is used, green numbers are displayed when the green light is used, and yellow numbers are displayed when the yellow light is used. The digital indicator light is well known in the art and will not be described in detail herein. The type of intersection is not limited to a crossroad, but can also be a T-junction or other types of intersections. The digital indicator lights are all displayed in reciprocal form.

The method comprises the steps of setting a solid N second line 3 in the range of 8-12 meters behind a vehicle forbidden line 2 by taking the vehicle forbidden line as an original starting point, enabling the N second line to cross the width direction of a road, taking the N second line as a waiting stop line of a vehicle when a red light is emitted, and defining an area between the N second line and the vehicle forbidden line as a vehicle driving assisting area. Research shows that 8-12 meters behind the vehicle forbidding line is a suitable length, if the length is less than 8 meters, the vehicle is difficult to form an effective starting state to a driving state, and if the length is more than 12 meters, the overall passing can be influenced.

When the red number corresponding to the red light is displayed as the Nth second from last, the vehicle positioned at the line of N seconds starts to enter the vehicle driving assisting area, the vehicle keeps a driving state from starting to entering the vehicle driving assisting area, and after the red light is changed into the green light, the vehicle drives through the vehicle forbidden line and drives to the road in the corresponding direction. When the red indicator light displays N seconds to the last, the vehicle can start to run, the vehicle can run to the vehicle driving assisting area at a lower speed at the beginning, then the speed of the vehicle in the vehicle driving assisting area can reach 25-35 km/h, the red light is changed into the green light, the vehicle can pass through the intersection more quickly by means of the running speed at the moment, and therefore the passing efficiency of the road is improved.

N is a natural number, and N is greater than or equal to 4 and less than or equal to 10. The preferable scheme is to set N to 5 seconds, 6 seconds or 7 seconds, and when set to 6 seconds, it is called a six-second line; set to 5 seconds, called the five second line; set to 7 seconds, called the seven second line, and so on.

The N second line and the vehicle forbidding line are arranged in parallel.

And the N second line is painted on the road surface by adopting white paint or yellow paint. The N second line and the forbidden line of the vehicle are made of different or same paints. To better draw the attention of the driver, the color of the N-second line is typically set to a different color than the prohibited-line of the vehicle. For example, the vehicle no-go line is often a white line, and the N second line may be set to a yellow line.

In addition, an indication nameplate is installed on the side edge of the road at the position of the N second line, and the indication nameplate is internally provided with the purpose description of the N second line. For example, the indication nameplate may have: the fast line is an N second line, and when the red indicating number is displayed to the last Nth second, the vehicle please drive forwards. Or other similar descriptions.

In this embodiment, N is set to 6, which is referred to as a six-second line. The six-second line is set at a position 10 m behind the vehicle forbidden line, the vehicle forbidden line is a white line, and the six-second line is a yellow line. When the vehicle runs to the position, the indicator light is red, and the first vehicle needs to stop waiting at the six-second line. When the red indicating number is 6, the vehicle can start at the moment, so that six seconds of advanced operation and running time are obtained for the vehicle, the vehicle obtains an initial running speed, a driver enters a driving state in advance, the speed of the vehicle is 20-35 km/h when the vehicle passes through a forbidden line of the vehicle, the vehicle can pass through the intersection more quickly, and the passing time is improved by 3-6 seconds. Through this transition, six seconds of efficient operating time is won for the vehicle. According to the number of times of converting traffic lights thirty times per hour, six seconds of operation time can be obtained by one time of converting the traffic lights, 3-4 vehicles are multichannel each time, 90-120 vehicles are frequently communicated one hour, the number of vehicles is calculated according to the length of 6 meters occupied by one vehicle, and the traffic dragon which is equivalent to nearly 700 meters is effectively dredged, so that the traffic jam of the road is effectively relieved. Moreover, the scheme is simple to implement, low in cost, high in efficiency and simple and convenient to operate.

Although the present invention has been described in detail with reference to the embodiments, it will be apparent to those skilled in the art that modifications, equivalents, improvements, and the like can be made in the technical solutions of the foregoing embodiments or in some of the technical features of the foregoing embodiments, but those modifications, equivalents, improvements, and the like are all within the spirit and principle of the present invention.
