What to do about detection?
DEMO- Trafficware in-pavement wireless PODS
~$120 to $180k in non-budgeted hardware to achieve detection requirements (video, microwave, in-pavement, loops)

Key Elements for Successful Multi-Jurisdictional Signal Coordination and Transit Signal Priority- Communication; Professional to Professional- Communication; Physical (Lynnwood installed fiber
optic conduit and cable then invited as appropriate) Edmonds and Mountlake Terrace. WSDOT- Traffic Busters and Connection of their Signal Controllers to their Central Signal System. Community Transit for Transit Signal Priority
- Professional and Technical Ability; Preventative Maintenance Program, Responsive to Complaints, Responsive to Knock-Downs, On-Call Schedule.

Key Elements for Successful Multi-Jurisdictional Signal Coordination and TSP (Continued)- Resources; Spare Parts, Test and Troubleshooting
Equipment. - Host Training and Refreshers- Check-in with Officials “Any Complaints?”- When Possible, Create Solutions to Problems and Offer
to Share. Examples: NTP Server for Controller Clocks. Leverage existing equipment for Transit Signal Priority.

STEP 7: Training by Trafficware
STEP 8: Acceptance Testing- TSP didn’t work with adaptive until
three weeks ago.
STEP 9: Verification/Validation Testing
Systems Engineering Complete

Lynnwood built in a retainage amount on contract. WSDOT Local Programs said we had ten years to finish spending grant.We encouraged Trafficware at every opportunity and talked it up with Community Transit.
So…how did things work with failing acceptance test on TSP?
From October 31, 2016 to April 15, 2019 we waited a long time but today everyone is happy and no one is unhappy.

Not entirely sure yet…
CONSIDERATIONS- Current Adaptive Deployments Break Up Corridors Into Segments; Different
Segments Can Be Different Adaptive Systems.
- Often Most Challenging Task of Any Signal Coordination Is Time Synchronization;Time Synchronization of Servers and Controllers to a Single Time Source is PossibleThrough Multiple Affordable Means.
