Computer modeling of the dependence of traffic flow on traffic load. (Senior Division).

This project is targeted at discerning the relationship between the rate of traffic flow along a road and various road factors. The program used for this study is based upon an array structure, which the cars use for both indicating location and as a database for determining other cars' locations. This data structure allows more complex car functions, as there is less time wasted on finding other cars. The movements of the cars are then measured by taking the data collected for the cars during the simulation and storing them in an Excel spreadsheet file. That file is then opened in Excel and the data manipulated to determine the flow rate of cars as traffic load increases. The results of the study so far are that traffic load is the most important factor in altering traffic flow. While the other factors in the simulation--base car speed, variance in car speed, road length, rate of car entrance, lanes and simulation time--do affect the traffic flow, their effects are either small or predictable.
