Book A Systematic Approach to Identifying Traffic Safety Needs and Intervention Programs for Indiana Volume I Research Report

Download or read book A Systematic Approach to Identifying Traffic Safety Needs and Intervention Programs for Indiana Volume I Research Report written by Andrew Tarko and published by . This book was released on 2014-12-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of JTRP Project: "A Systematic Approach of Identifying Safety Intervention Programs for Indiana (SNIP2)," which aimed to develop SNIP2 to support identification of roads that have excessive crashes of the types defined by the user. In addition, this tool is capable of selecting the best combination of high-crash roads and relevant safety interventions that maximizes the safety benefits and keeps the total cost within the budget and other user-defined constraints.Unlike other studies considering the implementation time of safety projects, the optimization objective of SNIP2 is to identify an optimal combination of countermeasures renewable within a long time horizon. This simplification is accomplished by representing the projects through their annualized costs and benefits. It allows consideration of many projects for large road networks and it makes the SNIP2 suitable for identification of safety focus areas in strategic safety plans. The SNIP optimizer--an heuristic approximation of a large-size mixed integer knapsack problem based on a greedy search was extensively tested and evaluated. It was found producing optimal or near-optimal solutions in a sufficiently short time. Another research result is a comprehensive catalog of countermeasures for Indiana--a list of countermeasure names, road and crash conditions for the countermeasure relevance, corresponding crash modification factors, and countermeasure costs.The SNIP2 is computer software developed with close collaboration with the INDOT future users. It includes an updated crash and state road database. A user's manual describes on the necessary details of the software and various aspects of its use. Two example studies are also included in the manual to illustrate its use and to better presents the SNIP2 features.

Book Indentifying Traffic Safety Needs a Systematic Approach

Download or read book Indentifying Traffic Safety Needs a Systematic Approach written by Andrew P. Tarko and published by Purdue University Press. This book was released on 2012-02-12 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
