- W156622142 abstract "Ever increasing vehicle volumes are forcing engineers to implement new transport systems to increase capacity of road networks in urban environments. Improvements in computer technology have seen the introduction of commercially operational computerised traffic simulations. Microscopic traffic simulation is a technique used by traffic engineers throughout the world as a cost effective tool to investigate the implementation of traffic systems.This study aims to investigate the effects of introducing such systems, using a microscopic traffic simulator. A traffic simulation model using AIMSUN2 was developed for the western Brisbane commuting corridor. This stretch of road network consists two major arterials, Coronation Drive and Milton Road, which link the CBD to western suburbs.A base model representing morning peak traffic conditions in year 2000 was constructed using data collected for a model developed in PARAMICS for other research. This model was calibrated using field data to within 2 percent accuracy for total intersection movements and 1 percent for individual movements. The model was then validated to within an average accuracy of 12 percent over three routes using travel time data.The calibrated and validated model was used to study the impacts brought upon by the upgrade of Coronation Drive to its present state (2002). The upgraded model showed a decrease of travel time by 7 percent for Coronation Drive inbound during morning peak travel conditions.Further investigations into the introduction of various types HOV lane using the 2002 model was undertaken. A transit lane, T3 HOV lane, T2 HOV lane and normal lane were each analysed as the western most lane along Coronation Drive inbound. The model showed that as the number of vehicles being able to access the leftmost lane increased, so did travel times. Public transport travel times were found to improve by 19 percent with a transit lane over a normal lane. Travel time deviations would also reduce by 68 percent with the introduction of a transit lane. A T3 HOV lane was found to provide a 14 percent improvement in travel times compared to a normal lane for single and multiple occupant vehicles.The work reported in this research thesis demonstrates the feasibility of using traffic simulation packages as an ideal way to evaluate the effects of implementing traffic systems to a road network. It also demonstrates the implications of installing such systems along a commuting corridor. This report also documents directions for future research using microscopic traffic simulations." @default.
