Abstract |
A methodology was developed to evaluate traffic congestion at school locations during the morning hours, when parents drive their children to school. The methodology is applied at two school sites in the Auburn-Opelika area of Alabama, and involves the development of a simulation model in GPSS/PC that replicates existing traffic conditions. The model simulates the arriving of vehicles, their entering the school driveway, parking, or dropping off students, and leaving the school site. As a result of high interarrival rates and low service rates at the two school sites, queues form on the adjacent street and disrupt traffic. Following model validation, selected components were changed and their effect on queue length was determined. An evaluation of alternatives was conducted to reveal the best recommendations for alleviating the school congestion problems. It was concluded that the methodology developed is a very efficient approach, because conventional methods do not directly apply. The methodology can be used in similar situations in which queueing of vehicles occurs or when the traffic patterns are too complex to describe analytically. Language: en |
