Background
Congress created the second Strategic Highway Research Program (SHRP 2) to address
the challenges of moving people and goods efficiently and safely on the nation’s
highways. SHRP 2 addresses four strategic focus areas.
- Safety: The role of human behavior in highway safety.
- Renewal: Rapid highway renewal.
- Reliability: Congestion reduction through improved travel time reliability.
- Capacity: Transportation planning that better integrates community, economic,
and environmental considerations into new highway capacity.
The SHRP 2 safety research plan includes two tracks: a large field study of driving
behavior using volunteer drivers and a sophisticated instrumentation package installed
in the volunteers’ vehicles (in-vehicle study) and a video system to record movements
of all vehicles at specific road sites such as an intersection (site-based study).
The in-vehicle study consists of three areas: 1) study design & field data collection,
2) roadway data and 3) analysis. Project S-03, “Roadway Measurement System Evaluation”,
fits under the roadway data area of the in-vehicle study.
The SHRP 2 Project S-03 will identify critical roadway feature characteristics and
evaluate the ability of vendors to collect the data at specified accuracy levels.
The rodeo itself will also be useful in identifying reasonable and technically possible
accuracy levels. The selection of the data and associated accuracy levels depends
heavily on the specific applications of the data.
To collect these critical roadway data elements, SHRP 2 will require the services
of a commercial mobile data collection vendor as part of Project S-04, “Acquisition
of Roadway Information.” Before procuring these services SHRP 2 must first evaluate
the existing commercial data collection capabilities. The S-03 project will perform
that evaluation.
Research Objectives
The objective of the SHRP 2 Project S-03 is to develop, organize, and conduct a roadway
measurement system evaluation (rodeo). The goals of this research are as follows:
- Pre-qualify commercial data collection vendors for bidding on the SHRP 2 Project
S-04: Aquisition of Roadway Information.(See
"S-04 Information" page)
- Evaluate the precision and accuracy of the mobile roadway and pavement inventory
data collection services as relates to selected roadway safety data elements collected
at highway speeds.
