Our next meeting is October 20th at the City Of Cupertino’s new TOC Yard, The meeting starts at 9:00am. Come and see the new facility.
Our guest speaker will be Mike Montoya with Advanced Traffic Products. He will be discussing the Wavetronix Smart Sensor which uses patented Digital Wave Radar to measure eight lanes of vehicle volume, occupancy, speed and classification.
The new TSA LED hats are now available. Get one for free with your membership renewal. See Dave Mooso at the meeting.
At the last TSA meeting on Wednesday. Mike Beck presented information on the MS SEDOC Intersector a new microwave based vehicle detector available from Western Pacific Signal. It provides motion and presence detection and provides a bicycle discrimination capability. The bicycle discriminattion detection is the most interesting feature. Now it is possible to provide traffic responsive bicycle appropriate traffic signal timing (green extension and clearance) for controllers that provide that capability like the Naztec NTCIP Based TS2 / 2070 Controllers.
The unit demonstrated provides eight zones of detection and four outputs so it is capable of detection for four lanes. To provide vehicle and bicycle detection for each of four lanes two zones would be needed for each lane but with the limit of four outputs, some lanes would have to be combined. In the future, modules with more zones and outputs will be available. Currently up to five units may be installed at the same intersection.
This feature is even more interesting with new legislation in California, AB1581, that requires new or modified traffic signal detectors to have bicycle detection capability.
Microwave detection, with these new features, may eliminate many of the problems associated with other technologies like video (weather and lighting) and loops (roadway cuts and damage by roadwork).
It looks like this technology may be capable of much more in the future. Queue detection would be nice for modified density features that can properly respond for right turn lanes and protected /permissive left turn lanes. More outputs, more zones, and the ability to link the units settings database to traffic management systems.
I’m looking forward to some long needed improvements to traffic control using detectors that provide bicycle discriminating features like this..
The California Street Light Association (CAL-SLA) has scheduled Conference No. 55 to be held in two locations:
SOUTHERN CALIFORNIA, April 22, 2010, Alhambra Room, LA, County DPW, 900 South Fremont Ave., Alhambra, CA
NORTHERN CALIFORNIA, May 26, 2010, Almaden Winery Community Center, 5730 Chambertin Dr., San José, CA
This conference is being held at no cost for government officials only, which provides an excellent opportunity for networking and discussing the issues related to street lights and traffic signals with your counterparts in other California cities and counties. Attendance will be limited to 100 attendees per site and registration is on a first come basis.
The Topics to be discussed include:
History of CAL-SLA and the need for every city and county to be an active member.
Discussion by the CAL-SLA attorney and economist on their activities on your behalf to keep the rates for street lights and traffic signals at the lowest possible levels.
Financing energy efficiency projects for cities, counties, and special districts by representatives from the California Energy Commission
A presentation on “Street Light Acquisition.”
Insights on the legislative process regarding energy issues as well as any new laws and/or upcoming energy legislation from a California State Association of Counties (CSAC) representative.
Round table discussion regarding the items discussed and the issues of interest for future conferences.
If you have any questions please call Mehdi Sadjadi, CAL-SLA Executive Director, at 415-250-3551 or email him at email@example.com
