Performance study of incident modelling on southern expressway using PARAMICS micro simulation software /

Patel, Narendra. Unknown Date (has links)
The purpose of the study is to use micro simulation as an evaluation tool to evaluate the performance efficiency of the Southern Expressway. This thesis work demonstrates the potential benefits of using microscopic simulation models when developing incident response and clearance strategies. The project findings, however, are expected to assist transportation officials and Government agencies in developing effective traffic management strategies in the event of non recurrent or incident. This thesis work also offers them a tool to evaluate the impact of any type of incident on transportation network operations. / In order to ensure that the transportation system is ready to support rapid and effective response to any kind of incident, facilitate the movement of people and goods even in times of congestion crisis, and capable to quickly restore services to full capacity and also to manage an incident effectively, it is necessary to calculate and estimate the incidents impact on traffic network. Basic analysis techniques widely used to estimate the loss of capacity due to incident are average speed, queue length etc. and these measures can be used further to support the formulation of a response plan i.e. route diversion etc. An important element of an effective incident management program is the ability to accurately estimate the freeway capacity remaining following an incident. In this thesis we used PARAMICS V 5.1 to model the Southern Expressway network, Adelaide during evening peak (17:30:00 pm) southbound traffic to measure the efficiency of the Southern Expressway in incident scenario. The PARAMICS V 5.1 name is a short form derived form PARAllel computer MICropic Simulation. The PARAMICS V 5.1 is a unique microscopic urban and freeway traffic simulation software package for modelling of movement and behaviour of individual vehicle on a road network and widely used for ITS modelling. / The traffic results determined after comparing 0, 15, 30 and 60 minutes incident duration with alteration of 1 lane lockage, 2 lane blockage scenario as well as 15 minutes blockage of all 3 lanes scenario. All Scenarios give the performance of Southern Expressway as well as to estimate the Southern Expressway capacity remaining following an incident. From the detectors network is able to count the total number of vehicles passing through that lane. Final result and calculated difference of each scenario can tell us the percentage diversion rate due to vehicles incident on Southern Expressway. Dynamic feedback assignment is re-routing every 5 minutes and gives direction to vehicles on less congestion routes. These diverted rates to other arterial roads are useful for further support of formulation of a response plan. To evaluate the performance of Southern Expressway network, measures of effectiveness (MOEs), such as average speed, queue length and delay in seconds as well as VHT (Vehicle Hour Travel) value of whole network considered and compared with Base condition or Non- Incident or 0 minute incident duration. The impact of incidents was found to vary with number of blocked lanes and incident duration. / From the results we can clearly observe that by using Dynamic feedback assignment we achieved up to 16 % diversion from Southern Expressway to Main South road. Average speed was 12 km/h during 2 lanes blockage scenario and reaches 91 pcus/lane/km queue length. Highest delay recorded for 155 seconds during 2 lanes blockage scenario and 45 minutes incident duration. 2 lanes blockage scenario has highest value of total Vehicle Hour Travel (VHT). / The final results of this research are important for planning capacity enhancing expressway improvements. As we know duration of incident and lanes blockage conditions are able to serve and uncover the strengths and weaknesses of current crash management and provide important directions for traffic management system improvements. / Thesis (MEng(TransportSystemsEng))--University of South Australia, 2006.
