| As a new retail mode, Hyper Merchandise Market (HMM) has appeared in the 1990s in China .as a result of its full range of products, reliable quality, reasonable prices and better shopping environment, HMM has been rapidly developed in China's big cities and developed coastal cities. However, along with the development of HMM, it causes serious traffic problems. Although supermarket has great attraction to crowd and prosper the shopping district, it increase traffic pressure on roads around HMM, deteriorates traffic conditions, and even leads to traffic jams. Consequently, it is necessary that analyse the traffic impact caused by HMM to urban road traffic, study on traffic impact degree in order to achieve harmonious development between HMM with urban traffic.Firstly, Having collected and analyzed the correlative data, the paper gives a summary for the research on traffic impact analysis both in and abroad, and an estimation as well. Then the aim of the paper is given. It also introduces the definition, the functional characteristics and the general layout form of HMM, at the same time analyzes the characteristics of the traffic flow around the HMM.According to the characteristics of traffic impact caused by HMM, this paper propose the computing method of the peak hour trip attraction forecast to the HMM base on crowd attracted rate in commercial zone. Then forecasts the background flow on network by introducing the methods of OD matrix estimation with TransCAD software. For the traffic impact analysis area, this paper proposes a computing method based on road saturated degree by peak hour flow rate. Evaluation index of traffic impact and evaluation method is proposed, and then the traffic impact degree is given in the endFinally, according to all those studies above, the paper verifies the way and course that evaluate the traffic impact to HMM, and puts forward to practical measures to relieve traffic impact, give advice for HMM both on choosing proper site and layout as well. |
