About Bob Shanteau

Transportation Engineering Liaison, CABO Consulting Traffic Engineer

Ask the traffic engineer: How are speed limits set?

Most people think that motorists base their speeds on the speed limit. But while that may be true on freeways and other high speed highways, it’s not true on lower speed roads and streets. On lower speed roads and streets, motorists base their speeds not on the speed limit but on how the road feels.

If you’re typical, that doesn’t feel right to you. You may be thinking to yourself, doesn’t everyone pay attention to the speed limit like I do? Continue reading

Report on 1/6/2010 Statewide Bicycling Task Force organizational meeting

On January 6, a bicycling task force was formed during a meeting in State Senator Kehoe’s Sacramento office. That meeting was successful and we now have a working task force in place, thanks to the team of bicycling advocates: representing the League of American Bicyclists, the California Association of Bicycling Organizations and the California Bicycle Coalition: CABO President and CBC Board member Jim Baross, CABO lobbyist James Lombardo, CABO Legislative Liaison Alan Wachtel, and CABO Transportation Engineering Liaison Bob Shanteau.

Below is a report on that meeting, but first a little background on how the meeting came about: Continue reading

Proposed Bikeway in Long Beach – Letter to CBAC

September 29, 2009

Ken McGuire, Secretary
California Bicycle Advisory Committee – MS1
P.O. Box 942874, Sacramento, CA-94274-0001

Subject: Proposal by City of Long Beach to Experiment with Separated/Protected Bikeway on the Left Side of Two One-Way Streets

by email to (email address deleted)

Dear Mr. McGuire:

The California Association of Bicycling Organizations (CABO) has reviewed the documents prepared by the City of Long Beach in support of a “protected bikeway” and notes that it fails to comply with the guidance and standards in the California Streets and Highways Code and Vehicle Code and in the Caltrans “Highway Design Manual”. In light of this noncompliance and the resulting potential problems of traffic safety, traffic operations, and the failure by the City to address the status of bicyclists as legitimate highway users, CABO hereby requests that CBAC adopt a finding that the Long Beach proposal fails to comply with these references and to forward this finding to the City of Long Beach. The reasons for this request are detailed below. Continue reading

Proposed Bikeway in Long Beach – Letter to CTCDC

September 21, 2009

Devinder Singh, Secretary
California Traffic Control Devices Committee – MS36
P.O. Box 942874, Sacramento, CA-94274-0001

Subject: Item 09-21 on 9/24/09 CTCDC agenda
Request by the City of Long Beach for Permission to Experiment with Separated/Protected Bikeway on the Left Side of Two-Way Streets (Rte 9-112E)

by email to (address deleted)

Dear Mr. Singh:

The California Association of Bicycling Organizations (CABO) has reviewed the subject Request to Experiment (RTE) and notes that it fails to acknowledge previous trials in California of separated bikeways, particularly in the City of Davis and the City of Palo Alto, both of which were abandoned in favor of the standard bikeways now defined in the California Streets and Highways Code, the Caltrans Highway Design Manual, and the California Manual on Uniform Traffic Control Devices. In light of this previous negative experience with separated bikeways and the potential problems of traffic safety, traffic operations, and the status of bicyclists as legitimate highway users, CABO hereby requests that CTCDC reject the subject RTE or, if the CTCDC feels that the RTE may still have merit, refer it to the California Bicycle Advisory Committee for a recommendation on action by the CTCDC. The reasons for this request are detailed below. Continue reading
