Performance assessment of Tetteh Quarshie interchange using computer simulation
(2010-10-05) Badu-Prah, Ato Kwamina
Interchanges on urban arterials have in recent years become an essential intervention for most of the shortcomings associated with at-grade intersections. However the absence of the knowledge of their real operations can pose a serious set-back after the infrastructure has been built. Interchanges are crucial structures in the operations and performance of an intersection in any traffic system. Analysis of the probable or potential performance of interchanges is essential to avoiding the construction of a structure that would not perform after being built or contribute to the problem it was intended to address. In the advent of modern computers traffic simulation models have been widely used in both transportation operations and traffic analysis because simulation is safe, less expensive and faster than field implementation and testing. The need for micro-simulation has become more important in cities where rapid growth takes place such as Accra which has about fifteen interchanges/overpasses and still counting. Therefore, the need for calibrating simulation models to local situations is urgent to assess the performance of interchanges and also project the performance in the future. The main objective of this research is to calibrate a micro-simulation models to assess the performance of Tetteh Quarshie Interchange.
