FROM: Michael D.McCluskey,Public Works Director
Prepared by: Debra Larson, Traffic Engineer
Al Cablay,Public Works Manager
SUBJECT: Traffic Signal Monitoring System Interconnect Conduit Installation,
Specification No. 97-06.
CAO RECOMMENDATION:
1. Approve plans and specifications for"Traffic Signal Monitoring System Interconnect Conduit:
SR 1 (Santa Rosa), SR 227(Madonna, Higuera, South,Broad) and Various City Streets,
Specification No. 97-06"
2. Authorize staff to advertise for bids
3. Authorize the CAO to award the contract if the lowest responsible bid is less than the
engineer's estimate
DISCUSSION:
The Traffic Signal Interconnection project was approved in the 1996-1997 Budget and consists of
two elements:
1. purchasing computer software and hardware
2. installing underground conduit and wire
The City Council previously awarded a contract to BI Trans Systems for QuicNet/4 traffic
management system software. This software will be designed for use by both Caltrans and the City
of San Luis Obispo.
This agenda report initiates the second part of the project: installing underground conduit and
traffic signal interconnection cable. The conduit will be placed mainly in State Highways 1 and
227,with signal cabling placed so that the Caltrans office on Higuera Street and the City's traffic
engineer at 955 Morro will both have access to the"outputs"of all signals on the State Highway
system. In addition, City staff will have access to about 70%of all City signals and be capable to
receive 100%of all signals eventually. With this information both Caltrans and the City will have
new tools to monitor signal timing and performance and will be able to adjust some of the key
functions from the office rather than out in the field.
CONCURRENCES
The Community Development Department has determined this project to be categorically exempt.
Caltrans staffinembers have reviewed the plans and specifications. An encroachment permit will be
obtained prior to work occurring within state rights of way.
