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."

Manual on Uniform Traffic Control Devices for Streets and Highways


Book Description

The Manual on Uniform Traffic Control Devices, or MUTCD, defines the standards used by road managers nationwide to install and maintain traffic control devices on all streets and highways. The Manual is important as it provides national traffic control standards for all public roads, and includes traffic signals, signs, roadway stencils, pedestrian crossings, and bicycle and pedestrian treatments. The Highway Design Handbook for Older Drivers and Pedestrians, being updated this year, is provided leading research information which may, as verified and tested, become standards in the MUTCD in future years. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px Helvetica}

Improving Traffic Control Effectiveness in Complex Work Zones


Book Description

Information from driver studies performed during the first year of the project identified several features and conditions that created confusion and anxiety in traversing the work zone. Many of these conditions represented deficiencies in the work zone traffic control from the standpoint of positive guidance principles. This report describes the efforts to tailor the application of positive guidance procedures to work zone traffic control installations reviews. Four key steps, hazard visibility assessment, expectancy violation determination, information load analysis, and information needs specification, are described in the context of traffic control at potentially complex work zones. A methodology is presented for applying these steps in a field review process to be performed as part of the work zone traffic control installation process.
