Assessment of parking demand impact on adjoining roadway network

Abstract

In Malaysia, as in many developed countries, the increase in demand for car parks usually outstrips the supply, especially in the inner cities and at shopping malls. Although vehicles using off street parking do not directly interact with traffic flow, it is common knowledge that on exit from the car parks they have direct impact on adjoining traffic flows. A study is conducted to determine the additional traffic flow onto the adjoining roadway form Jusco shopping mall. Besides, it also to compare the traffic flows on the adjoining roadway before and after additional vehicle volume from Jusco shopping mall. Then, it also will address the short term and long term impact of the parking under study with regard to access, off site impacts, on-site circulation, and non-site traffic and delivery routes. At the end of the study it can be concluded that; (i) existing peak hour traffic flows from adjoining roadway network are influenced by parking demand entry into Jusco shopping mall, (ii) impact of additional traffic flow onto the adjoining roadway from Jusco shopping mall is minimal in short and long terms provided the gates are automated, (iii) Circulation traffic flows has no impact whatsoever on adjoin roadways since they are circulating on private property, and (iv) the assertion that parking demand from Jusco shopping mall will have significant effect on adjoin roadways is null and void; where such assertions overlook the vehicle contributions of on-street parking and other developments in the immediate vicinity.
