Transportation Applications for Mobile LIDAR Scanning: State-of-the-Practice Questionnaire
The relatively recent emergence of mobile Light Detection and Ranging (LIDAR) technologies as a potentially transformative tool for numerous transportation engineering applications coupled with a lack of existing standards has resulted in the need for an improved understanding of how this technology is currently being implemented, and what challenges are limiting its adoption. To that end, a questionnaire was administered to State Departments of Transportation (DOTs) to document and evaluate the state-of-the-practice regarding mobile LIDAR in transportation applications. Representatives from each of the 50 U.S. states and 6 additional transportation agencies completed the questionnaire, for a total of 74 responses. A second service provider questionnaire was completed by 14 companies experienced with mobile LIDAR services. Interestingly, it was determined that more DOTs have used mobile rather than airborne LIDAR services in the last year, even though mobile scanning is a less established technology. Additionally, the results showed that DOTs perceive cost to be one of the most significant challenges to the adoption of mobile LIDAR, indicating that more evidence and education are required regarding benefit to cost comparisons of the technology. The questionnaire also revealed current struggles as DOTs transition from two- to three-dimensional workflows and modeling. These questionnaires established a technology adoption baseline that can be used to measure future progress and provide the foundation for national guidelines currently under development.
