Integrated Incident Decision-Support using Traffic Simulation and Data-Driven Models

Transportation Research Record: Journal of the Transportation Research Board, 2018

This paper introduces the framework of an innovative incident management platform with the main objective of providing decision-support and situation awareness for transport management purposes on a real-time basis. The logic of the platform is to detect and then classify incidents into two types: recurrent and non-recurrent, based on their frequency and characteristics. Under this logic, recurrent incidents trigger the data-driven machine learning module which can predict and analyze the incident impact, in order to facilitate informed decisions for transport management operators. Non-recurrent incidents activate the simulation module, which then evaluates quantitatively the performance of candidate response plans in parallel. The simulation output is used for choosing the most appropriate response plan for incident management. The current platform uses a data processing module to integrate complementary data sets, for the purpose of improving modeling outputs. Two real-world case ...

A traffic simulation approach to evaluating the benefits of incident management programs

2006

The work reported in this paper is part of a research project aimed at demonstrating the feasibility of using micro-simulation models to evaluate the potential benefits that can be realised from the integration of incident management strategies on both the arterial and motorway networks such that traffic can be diverted to least congested routes. Data collected from the test-bed on the Gold Coast and the Nerang Traffic Management Centre is being used to develop, test and evaluate incident management strategies under live conditions and develop route diversion plans. The project uses AIMSUN microscopic simulation to develop the strategies. For this paper, part of the simulation model for a major arterial road on the Gold Coast will be used to demonstrate the feasibility of the approach. Results of simulating incidents on the motorway and creating diversion plans to the arterial network are the subject of another paper submission and are not addressed in this paper. (a) For the coveri...

Assessment of Different Traffic Management Scenarios Using Microscopic Simulation: A Case Study

2008

This paper presents the results obtained from microscopic traffic simulation study conducted to evaluate different traffic management scenarios (alternatives) for congested links in the capital city of Sana'a. The main objective of implementing simulation technique is to assist decision makers to select the most suitable solution to manage the problem of traffic congestion in effective and scientific manner and less cost for one of the busiest roads in the capital city of Sana’a. Different real-life implementations of four types of traffic management scenarios were carried out. This includes Do Nothing, convert curb parking lane to effective traffic lane, waving/shifting public traffic vehicles (microbuses) to other routs outside the studied road and redesign the traffic signals. The Do Nothing scenario was considered as control/reference scenario. The improving or worsening due to implementation different scenarios was measured by comparing results from studied scenarios to tha...
