Mapping Findings
§Vehicle mounted technologies solution (LIDAR) provides the most detailed data for use as a core mapping solution
§Vehicle mounted technologies solution is relatively costly and requires an investment in resources including skilled personnel and equipment.
§The other mapping solutions will remain useful for change detection as well as for mapping under certain specific conditions.
§Collection, preparation, and use of mapping data completed at the TFHRC Testbed May 2012.
§Three lane-level applications were demonstrated using decimeter-level positioning techniques
□Lane departure warning
□Curve speed warning
□Signal Phase and Timing, at lane-level
§
§The solution is able to capture the most variety of features accurately and reliably
§Many key aspects of the solution can ultimately be automated, a key requirement for large scale deployment
§The solution provides data collection opportunity to meet several needs beyond connected vehicle thus has the potential for synergistic effort development
§The solution Can be more easily integrated into current mapping stakeholder activities including pavement monitoring programs as well as roadway asset mapping and inventory
