• Abstract:
  Many techniques for collecting highway inventory data have been used by state and local agencies in the U.S. These
  
  techniques include field inventory, photo/video log, integrated GPS/GIS mapping systems, aerial photography, satellite
  
  imagery, virtual photo tourism, terrestrial laser scanners, mobile mapping systems (i.e., vehicle-based LiDAR, and airborne
  
  LiDAR). These highway inventory data collection methods vary in terms of equipment used, time requirements, and costs.
  
  Each of these techniques has its specific advantages, disadvantages, and limitations. This research project sought to
  
  determine cost-effective methods to collect highway inventory data not currently stored in IDOT databases for implementing
  
  the recently published Highway Safety Manual (HSM). The highway inventory data collected using the identified methods can
  
  also be used for other functions within the Bureau of Safety Engineering, other IDOT offices, or local agencies. A thorough
  
  literature review was conducted to summarize the available techniques, costs, benefits, logistics, and other issues associated
  
  with all relevant methods of collecting, analyzing, storing, retrieving, and viewing the relevant data. In addition, a web-based
  
  survey of 49 U.S. states and 7 Canadian provinces has been conducted to evaluate the strengths and weaknesses of various
  
  highway inventory data collection methods from different state departments of transportation. To better understand the
  
  importance of the data to be collected, sensitivity analyses of input variables for the HSM models of different roadway types
  
  were performed. The field experiments and data collection were conducted at four types of roadway segments (rural two-lane
  
  highway, rural multi-lane highway, urban and suburban arterial, and freeway). A comprehensive evaluation matrix was
  
  developed to compare various data collection techniques based on different criteria. Recommendations were developed for
  
  selecting data collection techniques for data requirements and roadway conditions.
