Getting to our destinations, we often seek the better way to avoid traffic jams. In this study, we evaluate some routing policies in the view of the traffic flow at roads and intersections. This study is focused on a finite square grid graph. We assume origins and destinations are uniformly and independently distributed at nodes. The main results by computing traffic flows for each policy are as follows: (1) Increase the number of turns causes more traffic flow at the center, (2) The policy to avoid roads where heavy traffic is expected to occur causes heavy traffic on other roads, (3) To relieve heavy traffic on the road, a single left-turning route is desirable, (4) In ideal situation where the maximum inflow at intersections is minimizes, the maximum inflow at intersections is more than 7% more than the average inflow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
