Smarter Work Zones Project Coordination and Technology Applications

Publication Date: August 2016
Description: Aging roadway infrastructure and increasing highway congestion means additional road work, resulting in greater work zone impact on the motoring public. Based on 2013 crash statistics, an average of 131 injuries and 1.6 fatalities occur in highway work zones every day. Additionally, work zones are estimated to account for 10 percent of all congestion. 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.

Innovative Safety Solutions with Pavement Markings and Delineation

Publication Date: January 2016
Description: Pavement markings are a common and relatively low-cost treatment used by transportation agencies to delineate travel lanes, inform drivers of lane use restrictions and rules, and ultimately make roadways safer. This booklet presents several case studies that highlight innovative pavement markings that are intended to improve roadway safety by informing and warning drivers of certain aspects of the road, the road users, or the surrounding environment.

Improving Driver Behavior with Infrastructure Safety Countermeasures

Publication Date: April 2015
Description: Roadway crashes are a result of three primary contributing factors: human behavior, the roadway itself, and the vehicle. A combination of any or all of these factors may lead to a crash or increase the severity of a crash. The case studies in this publication illustrate how infrastructure safety countermeasures can impact driver behavior to improve roadway safety.

Preventing Vehicle Departures from Roadways

Publication Date: February 2015
Description: A Roadway Departure crash is defined by the Federal Highway Administration as “A crash in which a vehicle crosses an edge line, a centerline, or otherwise leaves the traveled way.” These crashes, comprising run-off-road and head-on collisions, tend to be more severe than any other crash type. In 2012, roadway departure crashes accounted for 56 percent of all motor vehicle traffic fatalities.

Emerging Safety Countermeasures for Wrong-Way Driving

Publication Date: February 2014
Description: Wrong-Way Driving happens when a driver, inadvertently or deliberately, drives in the opposite direction of traffic flow along a physically divided highway or its access ramps. These crashes are mainly head-on or opposite direction sideswipes which tend to be more severe in terms of type of injuries and number of fatalities. A recently conducted inquiry of the Fatality Analysis Reporting System (FARS) database revealed that an average of 358 people were killed in Wrong-Way Driving crashes each year over an eight year period (2004 to 2011).

BookCover_2013HFS_webSafety Opportunities in High Friction Surfacing

Publication Date: February 2013
Description: Roughly half of all fatal crashes occur at intersections or on horizontal curves. In horizontal curve crashes, it is often the case that the vehicle speed and curve geometry create a “friction demand” higher than what can be achieved with standard pavement surfaces. Intersection crashes often occur when driver error creates an unexpected need for increased friction demand to serve as a “speed countermeasure.” One low cost approach that has been shown to be effective in addressing high “friction demand” locations is the installation of a High Friction Surface Treatment (HFST).
