SHRP 2 Project S-04: Acquisition of Roadway Information
NOTICE! The total roadway mileage to be surveyed under the nation-wide S-04
project has not been determined at this point. SHRP 2 is still collecting information
to determine the final mileage.
Comprehensive roadway data in a geographical information system (GIS) database has
been identified as a critical need for the SHRP 2 safety program. Most states and
metropolitan planning organizations (MPOs) are improving their base maps and incorporating
them in a GIS. Some roadway data are generally included, however, the maps are not
comprehensive in that they sometimes cover only roads under the jurisdiction of
the state or MPO. More importantly, sufficient roadway data to support safety analysis
focused on roadway issues that are critical for the planned study of the relationship
of road characteristics to the risk of road departure are generally not available—particularly
information on the geometry and features of the road or on the shoulder. To achieve
its objective, SHRP 2 will require the services of a commercial vendor(s) to provide
accurate mobile data collection of roadway and roadside characteristics and features.
The Objective of Project S-04 is to produce a GIS database of roadway and roadside
characteristics and features that can be linked with the SHRP 2 in-vehicle driving
behavior field study (S-07). More information on project S-04 can be found at
