Problems solved by technology

[0003] In addition, the current setting method of non-motorized lanes in my country (adjacent to motorized lanes and separated by traffic markings) will easily lead to mutual interference between machines and non-motorized operations (unless isolation guardrails are added), and there will be serious traffic safety hazards. At the intersection, the parking and walking of non-motorized vehicles will have an impact on the operation of vehicles in the adjacent motorway, thereby inhibiting the capacity of the intersection

Embodiment 1

[0051] Step 1: Determine whether the road section meets the conditions for setting up parking belts

[0052] If the sum of the peak-hour queuing lengths at the entrances at both ends of the road is less than the total length of the road section, the conditions for setting up the parking belt in the middle of the road are met; otherwise, the conditions for setting up are not met.

[0053] For rebuilt roads, the queue length can be directly obtained through traffic survey; while for newly built roads, the queue length can be estimated based on the traffic signal control scheme generated by the predicted traffic volume.

[0054] The queuing length (L) is not only related to the red light time of the intersection phase (r), but also to the transmission time of the starting wave after the green light is turned on (t 0 )related. The queue length is estimated as follows:

[0055] L=5·N+(N-1)·d (1)

[0056] N=(r+t 0 ) q (2)

[0057] t 0 =r·q·t 1 / (1-q·t 1 ) (3)

Embodiment 2

[0091] as attached figure 2 There are two intersecting roads at the signalized intersection shown, one road is a two-way 8-lane road, the lane width is 3.5m, and each entrance is equipped with a left-turn lane, two through-going lanes and a right-turn lane; the other road is a two-way 4 lanes. Each entrance is provided with a straight right lane and a straight left lane. The distance between two adjacent intersections is 400m. Set up a temporary parking space as follows:

[0092] Step 1: Determine whether the road section meets the conditions for setting up parking belts

[0093] If the sum of the peak-hour queuing lengths at the entrances at both ends of the road is less than the total length of the road section, the conditions for setting up the parking belt in the middle of the road are met; otherwise, the conditions for setting up are not met.

Abstract

The invention provides an urban road integrated design method based on a parking demand. The urban road integrated design method based on the parking demand comprises the following steps: step 1, judging whether a road section meets the arrangement conditions of a parking area or not; step 2, judging whether an intersection spatial layout meets the arrangement conditions of the parking area or not; step 3, determining the positions and the lengths of bus stops; step 4, determining the position of the parking area of the road section and the arrangement form of parking spaces; step 5, determining a non-motor vehicle lane arrangement method. According to the urban road integrated design method based on the parking demand, provided by the invention, a part of idle road spatial resources is reasonably utilized for parking, so as to alleviate the problem of difficult urban parking; the problems of bus parking convenience and non-motor vehicle travel safety are comprehensively considered. The urban road integrated design method based on the parking demand provided by the invention is applied to urban newly-built roads or rebuilt roads, capable of reducing road construction work amount, saving investment, increasing parking supply, and avoiding the mutual interference between motor vehicles and non-motor vehicles on the basis of meeting the same traffic demand, and remarkable in the utilization efficiency and effect of the urban road spatial resources.

Description

technical field [0001] The invention belongs to the field of traffic engineering, and in particular relates to an integrated design method for urban roads based on parking requirements. Background technique [0002] With the rapid growth of car ownership, the contradiction between supply and demand of urban parking facilities has become increasingly prominent, which has aggravated road traffic congestion and chaos in urban traffic operation order. The bottleneck of smooth urban road traffic is not at the road section but at the intersection. In order to meet the traffic needs of motor vehicles in different directions, the entrance lanes at intersections are often divided into different functional lanes such as left-turning, straight-going, and right-turning. This eliminates the situation that the number of entrance through lanes is less than the number of opposite exit lanes, resulting in a waste of space resources for exit lanes. Based on this, for this kind of intersectio...
