Abstract

Preliminary designs were first evaluated using a computer simulation program and a full-scale test program. From these studies, tentative design parameters were selected, including the ditch and driveway slopes and the grate spacing. The end treatment developed in the preliminary studies was then subjected to full-scale prototype testing. These tests involved evaluation of the end treatment on a 6.7 to 1 driveway slope with a subcompact automobile. The end treatment was subjected to tests at 40 mph (64.4 km/h) and 50 mph (96.5 km/h).
