Before-and-after study was performed on ramp ending with stop sign and at ramp's intersection with one-way roadway; speeds and lags for day and night conditions were measured before and after ramp was paved red; four pneumatic tubes were placed on ramp at various distances from stop line; ramp traffic was registered on 20-pen recorder; speeds were computed using difference in time and distances between tubes; average speeds were determined for points 100, 200, and 318 ft from stop line.
