Transdyn, Inc. has recently designed, built and installed a Traffic Management System (TMS) for Transurban’s I-495 Express Lanes in Northern Virginia. The project included the addition of four new lanes on the Virginia side of the Capital Beltway and replacing $260 million-worth of ageing infrastructure. When it opens later this year, it will be one of the most technologically advanced roadways in the world and will provide faster, more predictable travel times to users.

Powered by Transdyn’s Dynac software, the TMS enables Transurban’s Express Lanes Operations Center to more efficiently manage both traffic and facilities operations.
From a unified operator interface, the software solution provides roadway use data to a dynamic pricing system, reduces congestion and travel times, enables automatic express lanes use and manages both CCTV and automatic incident detection cameras. Dynac’s GIS-based incident response system is integrated with multi-cast digital video to quickly and more accurately pinpoint incidents. Travel time and toll pricing information is provided to motorists via dynamic message signs.
The NTCIP-compliant centre-to-centre interfaces developed by Transdyn link the TMS to external agencies and sub-systems to allow the sharing of data needed for efficient traffic monitoring and control.
