All traffic signals shall be of mast arm support design unless a specific exemption is granted (e.g., temporary signal installation). 4. All signal poles must be designed within the right-of-way and be placed to keep sidewalks and ramps clear. Signal poles must be designed for optimum ADA usability. 5. All new or modified actuated traffic signals shall include Audible Pedestrian Devices (APD) and Countdown Pedestrian Signals.

All traffic signals shall utilize a 2070E traffic signal controller in a 332 cabinet. It shall utilize the City of Eugene Voyage software package and shall connect to the City's master traffic signal system. 7. Inductive loop design is the preferred method of traffic actuation. Video detection may be considered when design considerations are optimal or when inductive loop detection would not function as well as video detection. 8. Minimum size of conduit shall be 1 and % inches except that 1 inch will be allowed to a push button detection post. 9. Maximum conduit fill design shall be 25 percent. 10. Junction box (JB) fill shall not exceed NEC.
