Making the Connection: Advancing Traffic Incident Management in Transportation Planning: A Primer
2013
The intent of this primer is to inform and guide traffic incident management (TIM) professionals and transportation planners to initiate and develop collaborative relationships and advance TIM programs through the metropolitan planning process. The primer aims to inspire planners and TIM professionals to create transportation plans and programs that support regional TIM programs through TIM-focused objectives, performance measures, and TIM strategies and projects. The ultimate goal of this primer is to strengthen, support, and elevate regional TIM programs as a crucial, lower-cost strategy for reliability, safety, environmental improvements, and mobility. The primer explains the benefits for TIM professionals and planners of linking planning and TIM. It contains specific opportunities, supported by case studies, to integrate TIM considerations and stakeholders into the planning process. TIM planning sheets provide tangible examples of TIM objectives that can be drawn from, in whole ...
Enhancement of Freeway Incident Traffic Management and Resulting Benefits
2012
To improve traffic conditions on major highways plagued by non-recurrent congestion, most highway agencies have invested their resources in two principal operational programs: incident response and clearance, and traffic impact management. However, even with the widespread implementation of such programs, effectively minimizing the traffic impact caused by multi-lane blocked incidents remains a critical and challenging issue for most highway agencies. This research developed a multi-criteria decision-support system for determining the necessity of detour operations during incident management from an overall socio-economic benefit perspective. The developed system enables responsible agencies to consider all associated critical factors with preferred weights, including the direct benefits and operational costs, safety and reliability, accessibility of detour, and acceptability by travelers. This research is part of the authors' developed integrated incident managing system for th...
World Review of Intermodal Transportation Research, 2009
Abstract: This paper describes Rutgers Incident Management System (RIMS) software that is developed to evaluate the benefits of various incident management strategies and technologies. This tool can generate incidents and test various response strategies and technologies. South Jersey highway network is used as a test network due to the available historical incident data. The evaluated incident management strategies include the deployment of Variable Message Signs (VMS) to divert traffic during incidents and the use of Freeway Service Patrols (FSPs) for detecting and verifying incidents efficiently. The simulation-based evaluations also include the effect of cellular phone users in the network on the incident detection and verification times. The results show that the studied incident management strategies have positive impacts on reducing incident durations while being cost effective. More specifically, the deployment of VMS for diverting traffic in case of an incident results in a benefit cost ratio of 9.2:1; an additional service unit in freeway patrol results in reduced incident detection and verification time with a corresponding benefit-cost ratio of 3.9:1.
Improving the Quality of Traffic Records for Traffic Incident Management
2018
Traffic incidents in US roadways cause 25 percent of all delays experienced by users. The resulting congestion may lead to secondary crashes, increasing economic costs and further risking the lives of travelers. Traffic Incident Management is a process that detects, responds to, and clears traffic incidents as quickly as possible so that traffic flow is restored safely. This project analyzes the three TIM performance measures: Roadway Clearance Time, Incident Clearance Time and Secondary Crashes of Kentucky to identify a baseline for performance which may indicate potential for improvement. The study pinpoints different data sources, tools and technologies that can be used to collect and analyze TIM performance measures. Kentucky State Police (KSP) Crash Database and TRIMARC Incident Records are the two principal data sources used. In addition, Waze and HERE speed data are also examined for potential use. Lastly, the three national performance measures are summarized and analyzed. They comprise a baseline for future performance assessment.
TRAFFIC INCIDENT MANAGEMENT IN THE PRESENCE OF HAZARDS
Traffic incidents can result in different kinds of hazards (e.g., plumes) that influence the status of road networks, therefore there is a great need for incident management in the presence of the hazards. When incidents occur, the created hazards not only affect the normal road users (make them detour or blocked), but also influence the movement of first responders. Traffic managers, who are responsible for maintaining the road safety and traffic stability, should carry out quick and effective measures to manage the incidents. In this paper, we present four issues to help people better understand the situations that could occur in the management of incidents with hazards: 1). Evacuation in the presence of hazards; 2). 3D incident management; 3). Navigation support for first responders; 4). Navigation support for road users. To address these issues, we propose a solution which combines agent technology, geo-database, hazard simulation, and traffic simulation. Further research would be needed to investigate the potentials of the proposed solution in real applications.
Traffic Incident Management Quick Clearance Guidance and Implications
2016
Improving traffic incident management is one means to help reduce congestion, as traffic incidents account for approximately 25 percent of total congestion on U.S. highways. Between July and September 2012, 330 collisions were recorded for the I-66 corridor in Northern Virginia alone, of which 82 required more than 1 hour to clear. To improve its incident management efforts, the Virginia Department of Transportation’s (VDOT) Northern Region Operations recently piloted a quick clearance policy called Operation Instant Tow. With an instant tow concept, a tow truck and a Virginia State Police trooper are dispatched simultaneously to the site of specific incident types (e.g., lane blocking events), thus reducing clearance time. VDOT’s Operations Division is interested in the potential expansion of this initiative to other operations regions and the employment of other quick clearance initiatives currently not executed in Virginia. The purpose of this study was (1) to investigate traffic...
