Project Title: Guidelines for the Effective Use of Flexible Pylons for Congestion Mitigation, Access
Management, and Safety Improvement
URL: http://tti.tamu.edu/documents/0-6643-1.pdf
16. 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.17. Key Words 18. Distribution Statement
