IntroductionThis section will provide basic information on traffic signals, their purpose and needs, definitions of various commonly used terminologies, and other relevant information. This section will also discuss high-level concepts from the Traffic Engineering Manual and Intersection Design Guide and FDOT traffic engineering manual and intersection design guide as they apply to traffic signals.
WarrantsThis section will discuss the nine MUTCD traffic signal warrants as well as roundabout alternatives and funding challenges associated with either intersection control. This module should include an exercise to work through a basic signal warrant exercise.
This section will discuss traffic signal planning and design elements such as sight distance, geometry, volume, lanes, phasing (including left turn phase warrants), timing parameters, clearance intervals, cycle lengths, flashing yellow, etc. This section will also discuss the components shown in traffic signal design plans as well as details on NEMA phase sequences. Also, the FDOT standards and specifications and traffic signal field components such as signal poles and mountings, signal head and detector placement, detection types, street signs, flashing beacons, flashing walk and don’t walk signals, cabling, conduits, pre-emptions, and other ancillary equipment will be introduced.
Timing and Coordination
A high-level discussion regarding software will be included to address basic controller signal timing intervals, splits, cycle lengths offsets, along with the software capabilities. This discussion will describe the various timing software and split determinations will be discussed. Micro-simulation packages used for retiming. This module will also discuss signal timing related to yellow and all red clearances, pedestrians, bicyclists, and other vulnerable road users, including various signing and control types such as pedestrian hybrid beacons and RRFB’s. Add a simple timing exercise and a retiming exercise with and without pedestrian push buttons.
This module will address railroad pre-emption, transit signal priority, freight signal priority, and emergency vehicle pre-emption. A modern approach will be discussed on how to use probe data to monitor corridors and identify issues as well as the use of new technologies to perform traffic signal timing.
This section will discuss various types of controllers used around the state as well as discuss the need to upgrade to the highly capable 2070 and ATC controllers that have NTCIP 1202 and 1211 compatible processors. This section will provide training on controller programming concepts to identify capabilities and limitations of the most common controllers used within the state. A round-table discussion with the vendors will be included as a part of this training to discuss the possibility of improving or tweaking the firmware, hardware, or software for the controllers. A brief discussion on troubleshooting, how to access the controller memory, how to input timing plans, how to download history, etc. will be included.
