Transdyn was recently selected to design, build, and support the Intelligent Transportation and Network Communication Systems portion of the Dallas and Ft. Worth-based Lyndon B. Johnson (LBJ) and North Tarrant Expressways (NTE) Managed Lanes System (MLS). Both expressways will be expanded to accommodate new lanes and will be equipped with a new regionally supported, scalable MLS comprised of a toll collection system (TCS), an intelligent transportation system (ITS), a network communication system (NCS), and other various subsystems needed to manage all toll and traffic management operations in real-time.
The toll collection system is being delivered by Kapsch and will maximize net revenue and alleviate traffic congestion by utilizing a dynamic pricing algorithm within the toll setting module (TSM); Transdyn’s DYNAC® software will provide incident and roadway status information to the TSM needed to determine toll pricing. In return, the TSM will push toll prices back to DYNAC for display along the roadway to motorists. Drivers will have a choice to use the managed lanes and by-pass main lane congestion, thus improving travel times. Once completed, the LBJ and NTE expressways will feature one of the most comprehensive managed HOV lane systems in the country that allows faster traffic movement at more reliable speed by adjusting the toll rate as the number of vehicles fluctuate.
Powered by DYNAC, the ITS system will enable operations personnel to monitor and manage traffic flow and incident response via interfaces to field devices and subsystems such as dynamic message signs, air quality monitoring devices, a microwave vehicle detection system, a roadway weather information system, over-height vehicle detection systems, and digital video recording. The ITS system will display important TCS and TSM information to Operations Center personnel, allow data sharing with TxDOT and other traffic management centers, and enable monitoring of system performance, inventories and maintenance activities on a 24/7/365 basis. Additionally, the new system will facilitate enhanced reporting capabilities needed to comply with highway regulatory compliance.
Transdyn will provide project management, detailed design, procurement, systems integration, testing, commissioning, training, maintenance and warranty support, along with all ITS software and equipment. Alcatel-Lucent will be subcontracted to Transdyn for the NCS scope of work.
The LBJ and NTE Express improvements will be designed, built, financed, operated and maintained by the LBJ Infrastructure Group (LBJIG) and NTE Mobility Partners which represent a consortium of companies including Cintra US, a world leader in private-sector development of transportation infrastructure; Meridiam Infrastructure, a global public-private partnership investor/developer of public facilities; the Dallas Police and Fire Pension System, the first U.S. pension fund in the country to invest in the building and maintenance of a major toll road project; and W.W. Webber LLC, a leading Texas construction company.
