Traffic Control Systems in Construction Workzones
Author: R. A. RaubPublisher:
ISBN:
Category : Roads
Languages : en
Pages : 262
Book Description
Traffic control devices in workzones are intended to provide sufficient guidance to motorists to help prevent collisions, especially with construction operations, and based on study of their use in Illinois, they appear to be meeting the objectives. What has been discovered in assessing workzone traffic control and crashes is that collisions occur more frequently than reports show and in ways not necessarily addressed in previous studies. For the most part, traffic control devices (TCD) within the actual construction area require no changes. They are protecting the workers from the motorists. What leads to collisions inside the work area are reduced lane widths and lack of adequate escape, especially on limited access roadways. As a result, the most frequent type of collision is rear-end, often caused by drivers stopping or suddenly slowing because of distractions. Outside the work area, the problem appears more related to poor driving behavior and need for some improved guidance for motorists, especially within the merge areas. When taking into account the under-reporting of crashes, with the exception of increases in certain manners of collision such as rear-end, the crashes appear no more severe than crashes occurring outside such zones. Crashes with pedestrians (which includes workers) also appear no more likely than in locations without workzones. On the other hand, crash reporting appears unlikely to include portions of the workzone away from the actual construction area. Using a set of crash reports in which the workzone was defined clearly to include the approach, taper, and exit, analysis suggests that crashes are almost as likely to occur outside the actual construction area as within. It is these crashes outside which appeared more severe and more amenable to enhanced traffic control, especially enforcement. The report recommends practices which could reduce crashes in the approach and where changes or reductions in lanes occur. In addition to other recommendations, a model for a process to be used in generating and reviewing workzone traffic controls has been developed.
Traffic Controls for Construction and Maintenance Work Zones: Office function

ISBN:
Category : Roads
Languages : en
Pages : 128
Book Description
Volume I illustrates many of the typical worksites describing the most common conditions encountered. The information provided can be used to supplement local, state, and national standards. The topics include, among others: Public information, regulatory control, special traffic provisions, protection of pedestrians, flagging, temporary traffic signals, and nighttime procedures. Volume II is intended primarily for use by job site supervisors. It addresses the most common situations, problems and solutions that supervisors might be faced with. The topics include, among others: Emergency work moving operations, temporary traffic control devices, placing devices, temporary removal of signs, and pedestrian needs.
Roadside Design Guide
Author: Publisher: Amer Assn of State Hwy
ISBN: 9781560510314
Category : Bridge railings
Languages : en
Pages : 352
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."

Gravel Roads
Author: Ken SkorsethPublisher:
ISBN:
Category : Gravel roads
Languages : en
Pages : 112
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.
Work Zone Operations Best Practices Guidebook
Author: U.s. Department of TransportationPublisher: CreateSpace
ISBN: 9781508569206
Category : Transportation
Languages : en
Pages : 294
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.
