City of Tyler
ITS Master Plan Description of the System Needs This section summarizes the system needs identified in the Concept of Operations. A detailed list of high-level and low-level needs is provided in the Appendix. The City needs ITS to efficiently manage traffic and promote mobility in keeping pace with the growth of the City and take advantage of the smart technologies that the transportation industry has developed in recent years.
Central System Environment There is a need for the ATMS to integrate the entire traffic signal system and ITS devices on one network to monitor device performance, collect data, and troubleshoot. The environment for the system needs to provide sufficient processing speed, capacity, and expandability. There is a need for the environment configured by the City’s IT department to be scalable to support the expansion of the City’s signal network over time.
Central System Software and Advanced Transportation Management System
There is a need to maintain and upgrade the City’s ATMS
The Siemens TACTICS system has served the City well, but lack of an ongoing maintenance contract and reliable communication has hindered the City’s traffic management capabilities. There is a need to keep the version up-to-date for bug fixes and increased functionality. There is also a need to continue having a maintenance contract for operational support and troubleshooting.
The central system software needs to provide access and information (at varying levels) for Traffic Engineering staff, traffic signal technicians (who currently have a laptop to take home), and the Police and Fire Departments (to identify signals on flash). The central system software needs capabilities to integrate other traffic management functions as part of additional packages or modules. By doing so, the City creates a fully operational Advanced Transportation Management System, or ATMS. For the purpose of this study, the Central System Software is the module that controls traffic signals and operates within the larger ATMS platform, which provides for more comprehensive management and control of all field devices. The central system software shall provide alert capability, including communication status, signals on flash, and email alerts to related personnel. It needs to be adaptable to real-time conditions, and consistent and supportive of City's current process of providing open data. There is a need to support advanced functionality in the controller. The ATMS, which includes the central system software functionality, should include full control of all field devices (e.g. traffic signals, CCTV cameras, DMS) and include the consumption and use of high-resolution data for performance measures.
