Denver Regional Transportation District (RTD)


The Denver metropolitan area is a rapidly growing region that is served by the Regional Transportation District (RTD) for its mass transit needs. Created in 1969, the RTD is a public agency with a mandate to develop, operate and maintain the region’s mass transportation system for the benefit of 2.7 million people in the district. The District covers over 2,300 square miles and encompasses eight counties. RTD’s services include of the full range of mass transportation services including bus, light rail, para-transit and park-n-ride facilities.


The RTD won voter approval to expand and improve the rail and bus transit operation throughout the service area. Funded by Homeland Security, the initiative included the challenge of upgrading the existing analog video surveillance system to a more responsive hybrid system while keeping the existing surveillance system operational during the cross-over. Another requirement was to plan for new cameras to provide coverage for the additional transit stations. Further, most camera placements were in outdoor locations and open to the Colorado elements.The scope of the project included but was not limited to converting over 1000 analog cameras from analog fiber transmission to digital transmission and recording; conversion of the original management software to accommodate the digital format; implementation of a head-end digital matrix and 10 workstations at the regional command center; installation of 170 new cameras at 18 transit station platforms; and switching of all transit station platforms to digital. Finally, additional safety measures needed to be developed and implemented as part of the installation phase to minimize the dangers of working on active train platforms.



Working closely with RTD management and the various manufacturers, NAV was able to ensure that the reconfiguration of the system from analog to a hybrid digital solution was consistent with the technical specification and the commissioning was executed to NAV operation standards.

Featured in the system design are new Pelco IP cameras that, along with the existing analog cameras, are connected to a new fiber backbone for transmission to a centralized head-end digital matrix. The reconfigured video surveillance system is managed and controlled by the new Nice Vision VMS (Video Management System) platform which is fully integrated into specialized transportation video management software. Comprehensive in nature, the VMS provides RTD management with a complete picture for improved situational awareness. Additionally, a Pivot 3 Cloud Storage system complements the design, with a clustered storage design that more intelligently and efficiently supports the large data storage needs created by the RTD’s operational need to record and store images from the system’s approximately 1200 cameras.
