Abstract:

Cat-eye reflectors are retroreflective safety devices that can be used effectively in road marking to provide directional guidance on roadways. This paper examines the effectiveness of using transverse cat-eye reflectors in the driving lane as warning and traffic calming devices. Field measurements of speed and in-depth interviews with different driver groups were used to assess the potential benefits of using cat-eye reflectors in these applications. The results show that cat-eye reflectors, when used as traffic calming devices in urban area, can effectively reduce the speed in local streets. However, they have a minor effect in reducing speed on highways. Cat-eye reflectors can also be used as warning devices on both highways and local roads to alert drivers about the need to take action. The results of in-depth interviews with drivers showed that drivers prefer cat-eye reflectors over other alternatives such as rumble strips. Heavy vehicle drivers seem to be the driver group that favors the use of cat-eye reflectors the most among other driver groups.
