It is intended to be a decision support system to be used by planners and engineers to evaluate the
impact of work zones and determine strategies to reduce these impacts.
The importance
of work zone safety is a priority when exposed to the hazards of the motor public as well as other construction equipment.
Rear - end crashes are the most common type
of work zone crash and typically take place on roads with speed limits greater than 50 mph.
Traffic impact assessment is a key step in the
process of work zone planning and scheduling for transportation agencies.
The plaintiffs filed a personal injury lawsuit against the construction worker, claiming that his failure to place warning signs in
advance of the work zone resulted in the collision.
Each supervisor and one member of each crew is required to attend LTAP's Design and
Operation of Work Zone Traffic Control course
Deployment of Intelligent Transportation Systems (ITS) for dynamic
management of work zone traffic impacts, such as queue and speed management.
Proactive management
of work zone traffic operations is necessary to ensure motorist and worker safety, minimize travel delays, maintain access to local businesses and residences, and ensure timely completion of road work.
In 2010, Texas had the highest highway fatality rate and highest
number of work zone fatalities in the nation.
Predicting Safety
Effects of Work Zone Designs: Lesson Learned from NCHRP 17 - 61 Presenters: Mike Fontaine, VTRC; Jerry Ullman, TTI
Microscopic traffic simulation models enable transportation agencies to conduct detailed
analyses of work zone mobility performance measures during the planning and scheduling process.
Toward Zero Scholarships - The Foundation provides travel scholarships for children who have lost a parent, sibling, or caregiver to a roadway work zone accident until we can reduce the number
of work zone deaths.
This page includes links to databases developed by the clearinghouse staff to store various
types of work zone related information and resources collected since 1998.
Plans are also to establish a concept of operations (ConOps) that will explain how and why smart work zones should be used, establish the requirements for data warehousing of smart work zone data, and develop a dashboard
of work zone performance measures.
Achieve a level of knowledge towards evaluating and improving the level of data pertaining to the safety and operations
of work zones administered by the agency.
Work zone conditions can be reporting to traffic via Dynamic Message Signs (DMS) and in the
event of a work zone incident, the TIM includes plans to re-route traffic and notify police and first responders.
The driver behavior parameters are derived to replicate the flow and speed at the work zone taper and at roadway segments
upstream of the work zone.
Massachusetts DOT (MASSDOT) is working to develop and adopt business practices that will institutionalize the
inclusion of work zone ITS into projects when and where appropriate.
A common defense that is raised (whenever applicable) is that the driver was not given substantial
notice of the work zone's existence.
The past couple of weeks have involved moving everything
out of work zones, tearing out the things we are going to replace, finalizing budgets and making purchase decisions (both on our flooring project and our kitchen).
The drawers can be used to store special - occasion linens, glassware, flatware, and serving pieces, while the bench itself offers a spot for guests to chat with the chef without getting in the
way of the work zone.
Toward Zero Scholarships - The Foundation provides scholarships for loved ones of fallen or permanently disabled workers until we can reduce the number
of work zone deaths.
This subpart establishes requirements and provides guidance for systematically addressing the safety and mobility
impacts of work zones, and developing strategies to help manage these impacts on all Federal - aid highway projects.
The goal for EDC3 is to have 35 state DOTs implement business processes for planning, designing, procuring, operating, and evaluating work zone ITS technologies as identified in the Work Zone ITS Implementation Guide, and / or utilize at least one work zone ITS technology application for dynamic
management of work zone impacts such as speed and queue management, by December 2016.
This report examines the functionality of components
of a work zone and how they work together, the use of standard construction drawings of work zones, personal protective equipment of workers, possible hazards of work zones, minimizing risks and ultimately work zone safety training.
TRB's National Cooperative Highway Research Program (NCHRP) Web - Only Document 240: Analysis
of Work Zone Crash Characteristics and Countermeasures documents the research results of multiple analyses focused on developing an improved understanding of work zone crash characteristics and countermeasure effectiveness used to produce NCHRP Research Report 869: Estimating the Safety Effects of Work Zone Characteristics and Countermeasures: A Guidebook.
