Development Of Prototypes Of A Portable Road Weather Information System, Meha Kainth
Masters Theses
Weather conditions have significant impact on road safety and roadway maintenance operations. Road Weather Information Systems (RWIS) play a significant role in providing weather and surface conditions to transportation agencies to monitor weather events. Fixed installations of RWIS are used for weather and pavement surface monitoring. However, permanent fixture installations may not be feasible due to reasons such as cost, accessibility to the site, siting concerns, and terrain. Portable RWIS provide a cost-effective solution in areas where permanent weather station installation is not possible. This study discusses use and benefits of the portable RWIS and outlines the issues involved in …
Automated Detection And Counting Of Pedestrians On An Urban Roadside, Gayatri D. Prabhu
Automated Detection And Counting Of Pedestrians On An Urban Roadside, Gayatri D. Prabhu
Masters Theses 1911 - February 2014
This thesis implements an automated system that counts pedestrians with 85% accuracy. Two approaches have been considered and evaluated in terms of count accuracy, cost and ease of deployment. The first approach employs the Autoscope Solo Terra, a traffic camera which is widely used to monitor vehicular traffic. The Solo Terra supports an image processing-based detector that counts the number of objects crossing user-defined areas in the captured image. The count is updated based on the amount of movement across the selected regions. Therefore, a second approach has been considered that uses a histogram of oriented gradients (HoG), an advanced …
