Benz, Robert J. Guidelines for the Effective Use of Flexible Pylons for Congestion Mitigation, Access Management, and Safety Improvement, Transportation Research Board of the National Academies, Washington, D.C., Texas Transportation Institute (in progress, end date August 2012)

      The objectives of this project are to develop guidelines on/to:

(1) When and where pylons are suitable for implementation,

(2) Which type of pylons (curb mounted or fixed to pavement) is suitable for various applications,

(3) Determine optimal spacing for pylons,

(4) Determine buffer space requirements, and

(5) Determine daytime and nighttime visibility requirements.

This project will survey various agencies to synthesize qualitative and quantitative experiences to identify the best implementation practices of pylons. The synthesis will be supplemented with case studies and controlled experiments to develop guidelines for effective use of pylons for different channelizing applications.
