Roadside drainage ditches (roadside grassed swales) typically receive runoff directly from the road and water is infiltrated over the side slope of the ditch, similar to a filter strip. Water that runs off the side slopes then has a further opportunity to infiltrate as it flows down the center of the ditch. This research focuses on the volume reduction...

MRIGlobal developed an automated system to measure and display the distance between two instrumented vehicles traveling along a road. The system uses GPS modules and radio modems to send location information between the vehicles five times per second. A field software was developed to calculate the distance between the vehicles based on this GPS data in real...
