Curb Parking Supply Scale with Conditions of Dynamic Traffic

Starting with the two key factors of road breadth and the distance to intersections, the present paper analyzed the constraints of road conditions on setting curb parking lots and, by analyzing the influencing mechanism of curb parking on traffic capacity, constructed the compensation model of traffic capacity for motor vehicles on the parking road sections. Then, the paper went on to set the values of compensation coefficients for road breadth, vehicles in parking in and driving out, non-motor vehicles, and lateral clearance, so as to calculate, with the precondition of guaranteeing certain service standards, the maximal values of curb parking lots on road sections under the constraints of traffic capacity. In addition, it also constructed the driving speed model according to BRP resistance function and, via the analysis of “Friction” effect and “Blocking” effect of curb parking on traffic flows of motor vehicle lanes, measured the influence of curb parking on driving speed in order to exactly determine of maximal parking value under the condition that the minimal driving speed of motor vehicles can be ensured. Finally, for the purpose of finding the balance between dynamic and static traffic and of maximally utilizing the remaining road resources, the maximal number of curb parking lots shall be the minimal value to satisfy the constraints of road conditions, traffic capacity and driving speed.
