Abstract:

Flexible pylons are gaining popularity as traffic channelizing devices in a variety of applications. The

flexible pylons are less rigid (as compared to concrete barriers) enabling easier access for emergency

vehicles and provide more positive control than pavement markings for channelizing traffic. In general there

are also concerns with the effectiveness of flexible pylons when used as channelizing devices. Motorists

frequently strike flexible pylons, which can increase maintenance costs for agencies. In addition, broken

pylons may create safety concerns to motorists. While some standards exist to test durability of pylons, there

is a lack of guidelines for implementation of pylons. This project identifies factors that influence the

effectiveness of pylon implementations and develop guidance to effectively implement pylons on high speed

facilities. This report documents the tasks of the first year of research including: a state-of-practice review,

vendor survey, agency survey, case studies, and a synthesis of information.
