Special signs and pavement markings improve pedestrian safety. ITE Journal, 1996, 66, 28-35.

Abstract
Signs prompting pedestrians to look for turning vehicles and pavement markings asking pedestrians to “WATCH TURNING VEHICLES” were both effective in decreasing conflicts between pedestrians and turning vehicles at signalized intersections. The treatment also increased the percentage of pedestrians looking for turning vehicles when crossing the street. These data also showed that the sign and markings together were more effective than the sign or markings used alone.
