Description

Special engineering vehicle for simple overpass and traffic control method thereof

A technical field

The invention is a vehicle, and has no similar style.

Second, background Art

The urban road is characterized by narrow road, more crossing points and large traffic flow, along with the popularization of cars, the urban traffic jam phenomenon is increasingly serious, a large number of vehicles are jammed on the road for a long time each day, which causes huge waste of people, property and things, the delay time delays the work, the environment is seriously polluted, the traffic jam is often formed from the crossroad junction in the morning and evening peak time period according to observation, when the traffic flow exceeds a certain flow or the road is changed from wide to narrow and the lane is reduced, traffic jam can occur, the traditional method for widening the road is difficult to realize due to high building density, overhigh removal cost and scarce land resources in urban areas, the construction of an overhead or overpass also needs a large space, the cost is high, the realization is difficult, and the number-limited vehicle traveling means has poor effect due to large rigidity required by traveling, so that the problem of traffic jam cannot be solved by a good method so far.

Third, the invention

Vehicles entering a road junction typically divide into three lanes: the vehicle-mounted road-crossing system comprises a straight running vehicle, a left-turning vehicle and a right-turning vehicle, wherein the running routes of the right-turning vehicle and other vehicles do not cross and can be followed in and out, the passing of other vehicles is hardly influenced, and when the road is narrow, the lanes are few and share the lanes with the straight running vehicle, the flow on the straight running lane is increased; the invention includes two parts, namely, a simple flyover special engineering vehicle and a bridge thereof, and a simple flyover crossing road junction has no left-turn traffic control method, the invention can greatly reduce cross traffic, and the crossing traffic can be increased by several times, which is divided into the following parts:

1. the simple flyover special engineering vehicle (see the attached figure 2): the small-sized automobile crossing overpass is characterized in that the bottom surface of the hopper is an anti-slip slope surface with the gradient within the allowed range of a road from back to front, the tail part of the hopper is a movable bridge plate, one end of the movable bridge plate is connected with the bottom surface of the hopper, the other end of the movable bridge plate is arranged on the road surface, the front part of the automobile is a telescopic or foldable gantry type bridge plate and a support column, the width of the plate and the distance between inner gears on two sides of the hopper can facilitate the passing of small-sized automobiles, the small-sized automobiles can facilitate the passing of small-sized automobiles in the extended hopper, two engineering automobiles are spliced together in a face-to-face mode, a small-sized automobile channel is formed on the upper surface of the telescopic or foldable gantry type bridge, and the.

2. The traffic control method for the simple overpass road junction without left turn comprises the following steps: in order to reduce the crossing of the driving routes of the vehicles, the crossing uniformly prohibits the vehicles from turning left, and the vehicles turning left need to be capable of detouring to arrive, so that the simple overpass can ensure that the small-sized vehicles can pass through the crossing directly without waiting, and if the motor vehicle road entering the crossing is wide enough, the large-sized vehicles can pass through the right lane alternately (see figure 4); if the motor vehicle lanes entering the crossing are wide and narrow, the engineering vehicle should be parallel to the narrow road (see figure 5), if the motor vehicle lanes entering the crossing are narrow, the small vehicles on the road perpendicular to the engineering vehicle can pass through the gantry, and the large vehicles can only turn right (see figure 6); according to investigation, the number ratio of small cars to large cars on a road is usually 4: 1 or even 6: 1, and the special control measures are adopted, so that more than 80% of cars on two roads can directly pass through a road junction without crossing, non-motor vehicles, pedestrians and a few large cars can pass through the road junction through manual command, the alternate passing frequency of the cars is greatly reduced, the instantaneous passing amount of the road junction is equal to the sum of the instantaneous passing amounts of four lanes, so that large traffic flow can be borne, the blocked cars can be rapidly dredged and are not retained, and engineering cars are collected and driven to recover the road as before in peak time.

Detailed description of the preferred embodiments

1. The special engineering vehicle for the simple overpass is similar to a medium-sized van, and can be formed by modifying the existing medium-sized van assembly, the gantry bridge, the pillar and the movable bridge plate at the tail part are common mechanical parts, the gantry bridge and the pillar can be made into a guide rail moving type, the movable bridge plate at the tail part can be made into a folding type or a turnover type, the splicing part can be designed into a quick-release structure, splicing and disassembling can be completed in a short time, the face-to-face long bolt guide structures can be used for alignment, zero-distance butt joint is realized, the side-by-side vehicles can be used for alignment by the limiting block structures, and after the splicing is integrated.

2. After splicing, the traffic signal lamp at the road can be switched into manual control and can be set into a double-layer bidirectional straight-going state, non-motor vehicles, pedestrians and a small number of large vehicles carry out manual command traffic, and automatic control can be restored after the peak time period is over.
