Record Type: UTC

Active traffic and demand management (ATDM) is a collection of innovative approaches to dynamically manage traffic demand and efficiently utilize available roadway capacity by using real-time operational strategies. Speed harmonization in ATDM is possible by placing dynamic advisory speed signs and activating them based on real-time demand and capacity. The spacing of the dynamic signs and the degree of speed control would determine the degree of harmonization. This study will aim to find the optimal level of speed harmonization by addressing the following issues: (i) what level of speed harmonization is needed; (ii) how far apart and how many speed signs should be used in a given condition; (iii) what speeds would be optimal solutions and how dynamic should they be over time; and (iv) what level of demand control would create maximum speed harmony.
