Indentifying Traffic Safety Needs - a Systematic Approach
Author: Andrew P. Tarko
Publisher: Purdue University Press
ISBN: 9781622600212
Category :
Languages : en
Pages : 128
Book Description
The Indiana Department of Transportation (INDOT) manages road safety in Indiana through safety emphasis areas, identification of safety needs within these areas, and development and implementation of transportation interventions that address the safety needs. Indiana applies system-wide performance screening to state roads using the somewhat limited, non-integrated tools available to date. A site-specific countermeasure development and evaluation process (scoring) is being used to determine essential project intent and merit or cost-effectiveness. This project addresses the need for a unifying approach to data-driven identification of safety emphasis areas and safety improvement projects via a systematic evaluation of safety needs in the Indiana road network. Such a method must utilize a database that integrates the Indiana state network, traffic, road inventory, and crash data. A method for safety screening of state roads in Indiana was developed with the following screening tasks in mind: (1) Identifying high crash locations (segments, intersection, ramps and bridges), corridors, and areas in terms of high crash frequency, crash rate, or proportion of a particular crash type. (2) Facilitating program-based screening (e.g., shoulder widening, median improvement). (3) Facilitating special programs and projects (e.g., five percent report). In order to ensure the versatility of screening tasks and the data maintenance, four components were included in the screening tool: (1) data management, (2) standard screening, (3) roads clustering and special studies, (4) results presentation.

Evaluation of Highway Safety Improvement Projects and Countermeasures
Author: Ioannis Tsapakis
Publisher:
ISBN:
Category : Traffic safety
Languages : en
Pages : 225
Book Description
The Highway Safety Improvement Program (HSIP) is a core Federal-aid, state-administered program in which each state is required to develop and establish planning, implementation, and evaluation processes. The goal of evaluation activities is to determine if highway safety improvements are achieving the desired results and the investments are worthwhile. The goal of this study is to advance HSIP evaluation processes and practices at the Texas Department of Transportation (TxDOT) and evaluate the safety and cost effectiveness of HSIP projects and countermeasures or work codes (WCs) that have been implemented in Texas over the last few years. This research involved: a) reviewing safety and cost effectiveness evaluation methods, state practices, and tools; b) gathering and compiling TxDOT data and assessing their appropriateness for supporting HSIP evaluations; c) developing safety and cost effectiveness evaluation tools for segments and intersections; and d) evaluating the effectiveness of implemented HSIP projects and countermeasures in Texas. The results show that the evaluated projects have been effective from both a safety and cost perspective in reducing target fatal, suspected serious injury, and non-incapacitating injury (KAB) crashes. The safety effectiveness index of 387 evaluated segment projects (treated as one group) was 0.84, and the corresponding index of 70 intersection projects (treated as one group) was 0.74, indicating an overall reduction in target KAB crashes after the projects were constructed. The benefit/cost ratio of all segment projects was 71.9 and that of all intersection projects (treated as one group) was 145.6.
