Impact Evaluation On Implementing Bus Rapid Transit System Based On VISUM Simulation

At the beginning of this thesis, the Green Corridor which is an abounded railwayused to connect Malaysia and Singapore has been introduced as study background.Along with the fast growth of population and traffic demand in Singapore, some newtraffic infrastructures need to be built at this undeveloped area. As an efficient,environment friendly and high volume transit system, Bus Rapid Transit (BRT) systemis a good choice. After that, the concept and advantages of BRT has been introduced.Based on the origin of BRT, its importance has been discussed and the currentdeveloping condition of BRT around the world have been analysed and compared.Based on the above mentioned study background, one BRT system has beendesigned along the Green Corridor, and the macro simulation software VISUM has beenapplied to build the pre-BRT and after-BRT models which mainly consist of study areaand traffic network. Based on the four-step model, i.e. trip generation, trip distribution,mode choice and trip assignment, the models have been validated by using goodness-of-fit analysis. After the VISUM quantitative analysis of current traffic condition, the BRTsystem has been added into the existing traffic network. The performance and utilizationof BRT system have been analysed by VISUM model.Based on the results of VISUM simulation, the mobility, coverage, fare collectionstrategy of the BRT system has been analysed. By comparing the network performance,traffic analysis (transfer time, number of transfers, and access distance) and ridership ofpre-BRT and after-BRT models, the impact on traffic condition of the BRT system hasbeen evaluated, and the quality of service of the BRT system has been examined.At the end, based on the forecasting of population and employment in Year2032,future travel demand has been forecasted, and ridership has been re-analysed. Recommended improvements have also been proposed. Based on the above analyses,implementing the BRT system is a wise choice.Through the traffic macro simulation models built on VISUM, the existing andforecasting traffic conditions can be intuitively demonstrated. Based on the simulationresults, qualitative and quantitative comparisons can be made. Thus, the decision ofimplementing BRT or not has become more objective and convenient. In the future, thisVISUM simulation method can also be used to give a reference of the feasibility whiledesigning BRT systems in China.
