TE-25 Type 170 & 2070 Traffic Signal Controller
DescriptionThis interactive course covers both similarities and differences in between the Model 170 & 2070 traffic signal controller. These rack mount controllers interface with a variety of electrical cabinet assembly styles, including the ever-popular classic, Model 332 standard. This hands-on course provides working knowledge about the capabilities, applications, and operations of these two controller types, as well as how to program signal timing plans into the controller using various local intersection software programs. The course covers all key topics ranging from controller hardware, module options, diagnostic tools, and field applications. Course instruction includes in-depth implementation issues, and to how to upgrade from NEMA TS1, TS2, or rack mount controllers. The course combines lectures with classroom exercises, case studies, and hands-on controller labs.
- Hardware module & I/O differences between the Type 170 & 2070 controller platform
- Selection criteria and specification differences unique to each platform type
- Lessons learned from early installations, including use of diagnostic tools for each type
- Signal timing plan strategy for both free and coordinated signal operation. Central system integration, field communications, and NTCIP standard considerations
- Interfacing and signal timing strategies related to controller cabinet assemblies
- Strategies and best practices related to controller maintenance & operations (M&O), and safety
- Vehicle, pedestrian, and bicycle detection features available for each controller platform
- Planning for a successful mixed-use environment of 170 & 2070 controllers, and their associated central control software programs
- Advanced operations applications involving transit signal priority, mid-block pedestrian crossings, and peer-peer communications
- Advanced applications related to high-resolution data collection requirement for signal performance measures and connected vehicle operations
What You Will LearnStudents gain a working knowledge of both 170 & 2070 controller operation, including how to deploy the 2070 and integrate these controllers within the agency's jurisdiction. From the controller lab, students will also learn to identify each of the various controller hardware modules, their functions, expansion features, and limitations.
Who Should AttendAll individuals in electrical-maintenance fields, planning, engineering, and electrical-maintenance fields interested in gaining knowledge and proficiency of signal controllers should attend. Specifically, a need or study in the uses and operations of deploying traffic signal controllers in a field environment will benefit from this course. No prior background in traffic controllers is required, although basic knowledge of traffic signal timing is desirable. New students and returning "refresher course" professionals will benefit from the instruction related to both popular controller hardware styles.
