Highway Safety Improvement Program. Dover, Delaware.
WRA is the lead engineer for all aspects of DelDOT’s HSIP including the development of new safety programs in response to changing federal requirements. On an annual basis, WRA performs safety audits for high crash corridors throughout the state under the Hazard Elimination Program (HEP), and provides engineering services through final design for identified safety improvements. WRA developed Delaware’s first Strategic Highway Safety Plan (SHSP), including two updates to the Plan. WRA developed the first statewide red light enforcement program in Delaware in 2004 and continues to provide engineering support services to for this data-driven safety program. WRA is developing a systemic safety improvement program to address Delaware’s SHSP Emphasis Areas. For DelDOT’s Highway-Rail Grade Crossing Safety Program (HRGX), WRA developed a methodology to systematically identify and improve candidate rail crossings for safety improvements.
Services provided under the DelDOT HSIP include crash data analyses, safety audits, traffic analyses to support safety improvements, pedestrian and bicycle safety studies, traffic control device design, conceptual development of safety improvements, training programs, and plan and policy development.
Highway segments identified for program consideration were converted from a GIS database into a Google Earth-friendly file for ease of use by all program partners. GIS-based systemic analysis of crash concentration on road segments was conducted to help with identification of problem roadways.
