Summary

The purpose of this effort was to conduct a market analysis of the development of a statewide common location referencing system and the collection of the FDE/HSIP on all public roads.  The primary theory is that collecting additional roadway and traffic data, and integrating those data into the safety analysis process, will improve an agency’s ability to locate problem areas and apply appropriate countermeasures, hence improving safety.

Results

The results of the analysis are shown in the following sections.

Costs

The additional costs identified include the following three sets of data elements:

Methodology

Overview

Based on the results of the literature review, communications with States, discussions with experts, and review of the Office of Management and Budget (OMB) guidance (13), an appropriate methodology was developed to meet the objectives of this effort given the available information.  

Literature Review

The literature review for this research effort focused on identifying literature pertaining to the costs and benefits of collecting data.  This extensive search looked at sources both within the transportation industry and expanded to fields outside of transportation including forestry, medicine and health, ecology, water resources, and mining.  Literature from these fields was reviewed for any pertinent methodologies or findings that could be helpful to this research effort.
