There are NO impediments in the California vehicle code to dedicated bikeways with theor own traffic contro; devices.
Here is what a truly innovative community has already done:
"Bicycling in Davis is, simply put, great. Streets with minimal traffic, bike lanes and traffic calming. Bike-only light cycles at major intersections. A university campus closed to vehicle traffic. Miles of empty country roads just outside town. Abundant bike parking everywhere. Great transit--Amtrak, Greyhound, the county-wide Yolobus, and the UC Davis-run citywide service Unitrans--that facilitate a car-free lifestyle. A city government that proactively (imagine!) encourages cycling, going so far as to feature an 1890s style high-wheeler (also known as an "ordinary," "penny-farthing" or "scorcher") as the city symbol.
One prominent recent example of Davis' commitment to cycling is the newly dedicated Putah Creek Bike Path, which opened in October 2000. Built over 18 months at a cost of $4.5 million, the 12-foot wide Putah Creek path crosses under Interstate 80, helping cyclists avoid a busy traffic interchange. The project was financed by $750,000 in Proposition 116 funds, $250,000 in development impact fees, and $3.5 million in redevelopment agency funds. Imagine if San Francisco's city government were as serious about enhancing bike and pedestrian safety with the nightmarish Interstate 280-Cesar Chavez intersection.
The Putah Creek Bike Path is the newest section in the city's network of multi-use paths, which extends for more than 50 miles in dedicated right-of-ways with grade separations (bridges and underpasses) to minimize traffic interaction. This extensive path network complements another 50-odd miles of bike lanes on shared roadways. One particularly delightful feature of life in Davis is observing the morning and afternoon "rush hours" on the greenbelt paths, as groups of children travel to and from school on bikes, skateboards and scooters.
According to Tim Bustos, pedestrian and bicycling safety coordinator for the City of Davis, this safe, traffic-free path network was a critical factor in the recent vote by Davis residents to terminate the city's expensive school bus system. "Parents have a great sense of confidence about letting their children ride bikes," says Bustos. "The city's extensive network of greenbelts is critical, because it makes parents comfortable with their children cycling. They don't have to worry about their kids interacting with traffic."
Both Bustos and David Takemoto-Weerts, bicycle program coordinator for UC Davis, attribute the high rate of bicycle use in Davis to visionary city planning 40 years ago. "Because of certain unique features--mild climate, level terrain, a large population of healthy, young and cash-poor university students for whom cycling is a natural choice--Davis would have a high rate of cycling without doing anything," says Takemoto-Weerts. "However, it was Davis' decision in the mid-1960s to proactively encourage and protect cycling that has made it the most bike-friendly community in the country."
Davis has grown from 5,000 residents in 1960 to more than 60,000 today, spreading out over a larger area to accommodate that growth. Its character has changed as well, from a purely "college town" to a partial "bedroom community" for nearby Sacramento and even the Bay Area. According to both Bustos and Takemoto-Weerts, these changes could have easily crowded out cycling if it weren't for the proactive efforts of city residents, government leaders and city agencies to encourage cycling.
"Davis has had the advantage of being able to build cycling infrastructure as it has grown," says Bustos. "This is easier than trying to retrofit an older city like San Francisco. However, there's no excuse not to begin creating more favorable cycling conditions. A lot of communities waste time arguing over whether or not to provide for bicycles. In Davis, that argument is over. Bicyclists aren't asking for anything special. We only want the same consideration given to every other transportation mode."
There are challenges in Davis, to be sure. Car use continues to grow along with the city's population. (This is still a community in a car-centered nation, after all.) However, given the wide community recognition of the benefits of cycling, it seems certain that Davis will continue to provide a model for bike-friendly city planning."
The referenced PA report does not even mention Davis' dedicated bikeways or those in Europe.
Unfortunately the Palo Alto Process precludes learning from others.

" Caltrans DOES control what Palo Alto does on city streets....no green stop signs"
What in the world do green stop signs have to do with creating dedicated bikeways with heir own traffic control devices?
Innovation is halted when the answer always is somebody else won't let me - and progress is halted when you turn a blind eye to what others have already done very successfully.
"The provision of separate cycling facilities is the cornerstone of Dutch, Danish,
and German policies to make cycling safe and attractive to everyone. They are designed
to feel safe, comfortable, and convenient for both young and old, for women as well as
men, and for all levels of cycling ability. "
"Perhaps the most important reason for the higher levels of cycling in northern
Europeespecially among women, children, and the elderlyis that cycling is much
safer there than in the USA. Both fatality and injury rates are much higher for cyclists in
the USA compared to Germany, Denmark, and the Netherlands. Averaged over the years
2002 to 2005, the number of American bicyclist fatalities per 100 million km cycled was
5.8, compared to 1.7 in Germany, 1.5 in Denmark, and 1.1 in the Netherlands (see Figure
3). Thus, cycling is over five times as safe in the Netherlands as in the USA, which
probably explains why the Dutch do not perceive cycling as a dangerous way to get
"While bike paths and lanes help protect cyclists
from exposure to traffic dangers between intersections, they can pose safety problems
when crossing intersections. Thus, Dutch, Danish, and German planners have worked
continuously on perfecting the designs of intersections to facilitate safe cyclist crossings.
The extent and specific design of intersection modifications vary, of course, from city to
city, but they generally include most of the following:
• Special bike lanes leading up to the intersection, with advance stop lines for
cyclists, far ahead of waiting cars
• Advance green traffic signals for cyclists, and extra green signal phases for
cyclists at intersections with heavy cycling volumes
• Turn restrictions for cars, while all turns allowed for cyclists
• Highly visible, distinctively colored bike lane crossings at intersections
• Special cyclist-activated traffic lights
• Timing traffic lights to provide a "green wave" for cyclists instead of for cars,
generally assuming 14-22km/hr bike speed
• Moving bike pathways a bit further away from their parallel streets when they
approach intersections to help avoid collisions with right-turning cars
Given the very nature of roadway intersections, it is virtually impossible to avoid all
conflicts between motor vehicles and cyclists, but Dutch, Danish, and German planners
have done a superb job of minimizing these dangers. "
Pucher and Buehler Cycling for Everyone
Wikipedia on bikeways:
Yep - " A 2010 study in Montreal, Canada, by Lusk et al., compared the motor vehicle-bicycle crashes and injuries on six Montreal cycle tracks (physically separated bicycle-exclusive paths along roads) with comparable reference roads (a parallel road with approximately the same intersection frequency and cross traffic). The authors found 2.5 times as many cyclists rode on the cycle tracks compared to the reference roads. They also found that the relative risk of injury was lower on a cycle track than on the comparable reference road (the average being 0.72 the relative risk). They concluded that "[c]ycle tracks lessen, or at least do not increase, crash and injury rates compared to bicycling in the street"
The New York City Department of Transportation implemented a bicycle path and traffic calming pilot project for Prospect Park West in Brooklyn in 2010 and published their results in early 2011. It created a two-way bicycle path with a three-foot parking lane buffer and the removal of one lane from motor vehicles. They found that weekday cycling traffic tripled after the implementation; cyclists riding on the sidewalk fell to 3% from 46% (the count included children who are legally allowed to ride on the sidewalk); speeding dropped from 74% to 20% of all vehicles; crashes for all road users were down 16% and injuries to all road users were down 21%.
An unfunded 1997 study by William E. Moritz of North American bicycle commuters calculated a relative danger of different facilities based on the survey results of "[fraction of crashes] divided by the [fraction of miles ridden on that facility]". Moritz calculated a relative danger of 1.26 on a major street with no cycling facilities, 1.04 on a minor street with no cycling facilities, 0.5 for streets with bike lanes, and 0.67 for mixed use/"bike" path. The "other" category which mostly included sidewalks had a relative danger of 5.32. Moritz made it clear that this was "[n]ot a statistical or random sample of BCs [bicycle commuters]."
