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.
