Improved Video Speed Data

Currently, there is no method for obtaining accurate vehicle length data from the WSDOT video cameras. This data is needed to obtain improved, unbiased speed estimates. This project will develop software that will use the relative dimensions of vehicles in the traffic stream to filter out long vehicles on video images and calculate accurate, real time data inputs for the Washington StateDepartment of Transportation (WSDOT) speed estimation algorithm.
