Speed Management


Book Description

This Report addresses the key issues surrounding traffic speed management and highlights the improvements in policy and operations needed to reduce the extent of speeding.




Work Zone Operations Best Practices Guidebook


Book Description

This Work Zone Best Practices Guidebook provides an easily accessible compilation of work zone operations practices used and recommended by various States and localities around the country. The Guidebook is a reference document that can be updated with new approaches, technologies, and practices for effectively managing work zones and reducing the impacts of work zones on mobility and safety as they are identified. The best practices are descriptive, not prescriptive. They describe approaches that have been successfully used by transportation agencies, along with contact information to find out more from the agency using the practice. Each organization must determine which of these practices are best suited for its particular situation, considering all the site-specific factors that affect work zone operations.




Smart Solutions in Today’s Transport


Book Description

This book constitutes the thoroughly refereed proceedings of the 17th International Conference on Transport Systems Telematics, TST 2017, held in Katowice-Ustrón, Poland, in April 2017. The 40 full papers presented in this volume were carefully reviewed and selected from 128 submissions. They present and organize the knowledge from within the field of intelligent transportation systems, the specific solutions applied in it and their influence on improving efficiency of transport systems.




Gravel Roads


Book Description

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.







Managing Speed


Book Description

TRB Special Report 254 - Managing Speed: Review of Current Practices for Setting and Enforcing Speed Limits reviews practices for setting and enforcing speed limits on all types of roads and provides guidance to state and local governments on appropriate methods of setting speed limits and related enforcement strategies. Following an executive summary, the report is presented in six chapters and five appendices.




Work Zone Speed Management


Book Description

This synthesis documents information regarding the current state of practice for work zone speed management. The report compiles data, procedures, techniques, and technical issues related to observing and comparing work zone speeds. The speed management measures have been organized into four categories: engineering, operational, enforcement, and public education and outreach. Information included in this study was acquired through a review of the literature, two surveys of state department of transportation representatives in all states, a compilation of state agency public information campaigns, and follow-up interviews with select survey respondents from several U.S. states and one Canadian province.




Refine Process to Identify, Evaluate, and Adopt New Technologies and Identify New Proven Technologies for Indiana


Book Description

While focused efforts to understand and employ new technologies for the benefit of INDOT have been pursued successfully in the past, there remains an opportunity to develop a robust approach to need identification and related technology selection and adoption that is more “continuous” in nature and capable of helping the organization keep pace with the rapid rate of technological change. In response, this study builds on the more than 40 years of work that has been carried out on this topic in the transportation sector and complements these efforts with insights from a wide variety of successful organizations in other fields to put forward a comprehensive approach to identify, evaluate, and adopt new “proven” and/or “ready to use” technologies that have the potential to improve INDOT’s ability to perform its multifaceted mission. This proposed process, which encompasses need identification, solution identification, solution evaluation, and staged solution implementation, incorporates several novel features to ensure effective technology adoption, namely: a new means of assessing INDOT needs that relies upon a survey of end-user “jobs-to-be-done” to focus technology adoption efforts; a web-based mechanism to link INDOT needs and potential solutions that is based on leading systems in the commercial sector; provision for “champions” that will provide idea “ownership” in the technology adoption process and help overcome traditional barriers; centralization of evaluation activities to drive efficiencies across INDOT and eliminate redundant efforts; and, a unique assumption-driven approach to implementation that optimizes resources and includes a tiered marketing strategy to build awareness and encourage broad adoption of technologies. In addition, this report provides recommendations for a governance structure that can guide the technology adoption process and ensure its on-going effectiveness. A pilot of the initial stages of the proposed process is also presented which calls attention to a series of INDOT-specific needs and associated high-potential technology-based solutions that if pursued could directly enhance INDOT operations. Overall, the results of this work provide the foundation for a capability in technology awareness and adoption that will benefit INDOT operations for many years.




Roadside Design Guide


Book Description

This document presents a synthesis of current information and operating practices related to roadside safety and is developed in metric units. The roadside is defined as that area beyond the traveled way (driving lanes) and the shoulder (if any) of the roadway itself. The focus of this guide is on safety treatments that minimize the likelihood of serious injuries when a driver runs off the road. This guide replaces the 1989 AASHTO "Roadside Design Guide."
