Zone Impacts Assessment: An Approach to Assess and Manage Work Zone
Safety and Mobility Impacts of Road Projects
Work zone impacts assessment is the process of understanding
and managing the safety and mobility impacts of a road construction,
maintenance, or rehabilitation project. Assessing work zone impacts
is important for developing effective work zone TMPs that provide for
safety, mobility, and quality in maintaining, rehabilitating, and rebuilding
our highways. This Guide presents a general approach for work zone impacts
assessment, mirroring the typical program delivery process of transportation
agencies. It also provides examples of how agencies are currently assessing
and managing work zone impacts, as well as an overview of different
traffic analysis tools that may be used for analysis of work zone impacts.
The Guide is intended to help transportation agencies in their efforts
to make work zones work better and is the fourth of four guides to help
agencies implement the updated Rule on Work Zone Safety and Mobility
(23 CFR 630 Subpart J). (US Federal Highway Administration report FHWA-HOP-05-068,

Investigating
the Impacts of Rainy Weather at Isolated Signalized Intersections
Various studies showed that the impact of weather on
traffic flow is a topic that is of much interest to researchers and
transportation officials. This thesis examines the impacts of wet weather
on traffic flow and signalized intersections, and it also examines the
feasibility of mitigating these impacts. (University of Virginia Center
for Transportation Studies Report UVACTS-15-30-90, January 2006, 189
p.)
Road Weather Management
Program
The Road Weather Management Program, within the FHWA
Office of Operations, seeks to better understand the impacts of weather
on roadways, and promote strategies and tools to mitigate those impacts.
Envisioned is a system that provides “Anytime, Anywhere Road Weather
Information” for road users and road operating agencies, as well
as a robust, competitive market for road weather services. Program goals
are organized into four areas: enhancing observing capabilities, training
and outreach, advancing the state-of-the practice, and promoting coordinated
research. (US Federal Highway Administration
Office of Operations Program)
Australasian Road
Safety Research, Policing and Education Conference Proceedings Internet
site
The Road Safety Research, Policing and Education Conference
is an annual event which provides an opportunity for road safety practitioners,
researchers and police to meet and discuss the latest road safety activities
throughout Australasia. The Internet site has been established to provide
access to proceedings of each Road Safety Research, Policing and Education
Conference held.
Speed
choice: the influence of human, vehicle and road
At present, an average of 40 to 50% of all drivers offend
against the speed limits. Often, drivers choose to speed on purpose,
but often it happens unintentionally. This fact sheet discusses the
factors which influence the drivers' speed choice. The fact sheet shows
that the speed choice depends on factors like personal preference, social
circumstances, road features, vehicle characteristics, and all sorts
of interactions between these factors. (Netherlands SWOV Institute for
Road Safety Fact Sheet, December 2006, 6 p.)
