Analysis about the influence by which the structure of the parking lot entrance way in a large-scale retail store gives it to a traffic accident and traffic flow

Abstract

Deterioration of the traffic environment around the large-scale retail store becomes a problem by traffic congestion caused by the location of the large-scale retail store and increase in the traffic accident occurrence number around the store. In this study, we focused on the structure of the parking lot entrance, which is considered as one of the factors of the deterioration of the traffic environment around the large-scale retail store, and analyzed the traffic flow phenomenon of the parking lot entrance by grasping the actual condition of the structure and video camera observation investigation for Utsunomiya City, Tochigi Prefecture. In addition, the accident occurrence situation near the parking lot entrance was analyzed. As the result, this paper clarifies the actual condition that many parking lot entrances become not only a trouble for smooth running of incoming and outgoing vehicles by structural problems, but also a bottleneck of a road in front of a parking lot. In addition, this paper clarifies the actual condition that traffic accidents between automobiles occur more frequently in the vicinity of parking lot entrances and exits with structural problems than those without problems.
