Algorithms For Lidar Based Traffic Tracking: Development And Demonstration, Vamsi K. Bandaru
Open Access Theses
The current state of the art of traffic tracking is based on the use of video, and requires extensive manual intervention for it to work, including hours of painstaking human examination of videos frame by frame which also make the acquisition of data extremely expensive. Fundamentally, this is because we do not have observability of the actual scene from a camera which captures a 2D projection of the 3D world. Even if video were to be automated, it would involve such algorithms as RANSACK for outlier elimination while matching features across frames or across multiple cameras. This results in algorithms …

Recent studies by the Construction Industry Institute have indicated that for a typical $100 million construction project, between $500,000 and $1million is spent on keeping track of where things are on the site and monitoring the status of construction activity. The emergence of scanning lasers has made real-time updates and earthwork calculations of the construction site a viable technique. The gathering of data is non-intrusive and will not impede the construction progress. The scanned data are imported using the import module.

JTRP Technical Reports
Design data collection involving the use of Lidar instrument, in conjunction with GPS proves to be very effective. Data required to model two bridges over the I-70 was collected on a single day, involving five and six sessions with Lidar equipment. Even though the data was collected on two bridges, it did not cause any disruption of the traffic, either on the Interstate or on the bridges. A major cause of concern during survey activities, particularly along interstates is safety, both for the motorists as well as the people involved in data collection. Lidar data collection was found to be …
