Download or read book Strategic Intersection Safety Program Guide written by Ingrid B. Potts and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Strategic Intersection Safety Program Guide is a tool to assist agencies at the State and local levels in developing strategic, systematic approaches for planning, developing, implementing, and maintaining an intersection safety program. It provides insights for how a strategic process for improving intersection safety can influence the selection of future projects that have measurable safety outcomes, such as reduction of specific crash types that help achieve strategic goals. This guide provides a step by step process for a strategic intersection safety program, including steps for the development of specific intersection safety action plans. It can assist in the development of the intersection-related portions of a State Strategic Highway Safety Plan (SHSP) and assist local agencies in aligning their intersection safety programs with the SHSP intersection safety goals. A summary is included of the intersection-related goals and improvement strategies incorporated by States in their current SHSPs as a resource for local agencies creating their own intersection safety program and for State agencies updating their SHSPs or developing an intersection safety program.

Download or read book Traffic Signal Timing Manual written by U.s. Department of Transportation and published by CreateSpace. This book was released on 2015-02-20 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report serves as a comprehensive guide to traffic signal timing and documents the tasks completed in association with its development. The focus of this document is on traffic signal control principles, practices, and procedures. It describes the relationship between traffic signal timing and transportation policy and addresses maintenance and operations of traffic signals. It represents a synthesis of traffic signal timing concepts and their application and focuses on the use of detection, related timing parameters, and resulting effects to users at the intersection. It discusses advanced topics briefly to raise awareness related to their use and application. The purpose of the Signal Timing Manual is to provide direction and guidance to managers, supervisors, and practitioners based on sound practice to proactively and comprehensively improve signal timing. The outcome of properly training staff and proactively operating and maintaining traffic signals is signal timing that reduces congestion and fuel consumption ultimately improving our quality of life and the air we breathe. This manual provides an easy-to-use concise, practical and modular guide on signal timing. The elements of signal timing from policy and funding considerations to timing plan development, assessment, and maintenance are covered in the manual. The manual is the culmination of research into practices across North America and serves as a reference for a range of practitioners, from those involved in the day to day management, operation and maintenance of traffic signals to those that plan, design, operate and maintain these systems.

This book was released on 2018 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: With more than 80,000 unsignalized intersections in Virginia, determining how and where to focus limited highway safety resources through deployment of low-cost, high-benefit systemic countermeasures is paramount to beginning to reduce the number of fatal and injury crashes at unsignalized intersections in Virginia. The purpose of this study was to develop a safety improvement plan for unsignalized intersections using systemic low-cost countermeasures. The scope of the study focused on unsignalized intersections with stop sign control on the minor approaches. Virginia’s unsignalized intersection crashes over a 5-year period were assessed to determine predominant crash trends and crash types to target for treatment. Three Virginia Department of Transportation (VDOT) databases (crashes, roadway inventory, and traffic counts) were combined for unsignalized intersections. Four focus collision types with the highest frequency of crashes and the greatest potential reduction in crashes were identified from the data: 3-leg angle, 3-leg fixed object off road, 4-leg angle, and 4-leg rear-end. Chi-square automatic interaction detection (CHAID) was used to perform a systemic analysis to identify a group of intersections based on independent variables (roadway inventory and traffic count variables) that were most strongly related to the focus collision types. After the crash assessment was performed, case studies of selected intersections in each group were reviewed to assess the factors that might influence the four focus collision types. A tiered list of countermeasures to deploy was developed based on the literature and input from VDOT staff. The countermeasures were intended to warn of the stop ahead, to make the stop sign and stop location more visible on the minor street, and to warn of the intersection ahead on the major street. The potential for safety improvement measure was used to prioritize the candidate treatment intersections. Before deployment, a study of the intersections conducted by district traffic engineering staff is planned in order to finalize the safety improvement plan. The output of the study is a safety improvement plan to deploy treatments to unsignalized intersections systemically as part of the safety program. The plan can be adjusted based on available funding.

This book was released on 2022 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovative intersections and interchange designs is one strategy known to enhance the operational and safety performance of our roads. Innovative designs specifically lead to an improved signal progression and result in reduced travel times, delays, crash severities and frequencies. Connected Vehicle (CV) technology is another strategy that has enabled dozens of Intelligent Transportation Systems (ITS) applications with the potential to bring major safety, mobility and environmental benefits. Many studies have focused on exploring each strategy when implemented solely. Therefore, one of the goals of this dissertation is studying the impacts and benefits of the combined implementation of the two strategies, while the other lies within developing a new innovative interchange design called the Continuous Green-T Partial Cloverleaf A (CGT-parclo A) and exploring its operational and safety aspects. A microsimulation approach was followed to achieve these goals.The results show that the combined implementation of CVs and innovative intersections has reduced travel times, and delays by nearly 65.3%, and 29.2%, respectively. Additionally, the total number of conflicts, rear-end and lane change conflicts dropped by nearly 23.8%, 23.6% and 24.4%, respectively at full Continuous Flow Intersections and 100% MPRThe CGT-parclo A exhibited superior operational performance to a multitude of interchange designs in most tested cases. The CGT-parclo A reduced travel times, and delays as high as 55.7%, and 69.8%, respectively, compared to the parclo A and parclo progressA. The CGT-parclo A is the best form of parclo A interchanges in terms of reducing the likelihoods, severities and frequencies of crashes.

Book excerpt: This Guidebook contains information that should be useful to engineers as they consider alternative solutions to traffic safety concerns at side-street STOP controlled intersections. It is the intent of this guide to provide the engineer information to aid in the consideration, selection and deployment of LED STOP signs and ICWS at these intersections. These safety strategies should be included for consideration along with other safety improvements detailed in the TEM and Traffic Safety Fundamentals Handbook such as improving visibility of the intersection with improved signing, pavement marking, and intersection lighting; improving sight distance by providing clear sight triangles on all approaches; selecting appropriate traffic control such as ALL WAY STOP; and reduce conflict points through geometric design such as turn lanes or bypass lanes. A shorter, quick reference version of this guidebook was developed as well and can be found at the link listed above.

Download or read book Toolbox to Assess Tradeoffs Between Safety, Operations, and Air Quality for Intersection and Access Management Strategies written by and published by . This book was released on 2008 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant transportation agency resources are allocated to meet maintenance, operations, safety, and air quality goals. Although there is a significant amount of overlap between these areas, decisions to meet agency goals in one area often do not consider goals in the others and, as a result, miss opportunities to leverage funds and make better informed decisions overall. There are a number of areas of overlap between capital improvements designed to improve operations, maintenance, safety, and air quality goals that provide a rich opportunity to leverage funds and use resources more cost-effectively while meeting agency goals in two or more of the areas. The objective of this research is to develop analytical tools that can efficiently evaluate common capital projects used to meet agency goals in one area (operations, safety, air quality, and maintenance) but that also have a significant impact on the others.
