Study On Temporary Parking Planning Of Special Events Of Small And Medium-sized Cities

In recent years, the number of special events held by some small and medium-sized cities is growing. The sharply increased traffic demand and traffic flow in a short time bring a huge pressure for the transportation infrastructure around the event venues. As the vital part of transportation system, the temporary park planning scheme directly affects the urban transportation and the events.Firstly, this paper defines the size of the small and medium-sized cities, choosing the key object of study which has a fixed time and space. It analyses deeply from three aspects respectively covering the demand characteristics, traffic flow and parking characteristics and provides guidance basis for creating an efficient and reasonable temporary parking planning scheme.Secondly, it analyses the mature case system of large cities and puts forward the traffic organization and management measures systematically for small and medium-sized cities from three aspects covering the classification and management of traffic control and parking transfer, parking information release. It determines the basic scope of the distribution of the parking lots, considering comprehensively the walking maximum and the patrol traffic affect to the key nodes. It puts forward a transfer concept which takes sight-seeing cars as the main body with a variety of ways as supplement and it also strengthens the parking information release in multiple forms.Finally, it establishes a multi-objective temporary parking location model from the perspective of the supply and demand, considering route-choosing behavior and the facility location theory. This model is targeting at minimizing the cost of park and ride and the transfer facilities which can be simplified as a single objective function by defining the weight coefficients. It puts forward the ant algorithm to solve it in view of the complex nonlinear model.Taking the China (Shouguang) International Vegetables Fair as an example, this model can be applied and verified, thus providing a practical case for the temporary parking planning of the special events of small and medium-sized cities.
