City of Tempe tests ‘Bike Box’

The City of Tempe installed a bike box on the east side of 10th Street at Mill Ave.  Note that in that google street view, there is already a bike box on the west side of the same intersection, installed by ASU according to the news item (apparently ASU and not the City of Tempe has jurisdiction over that piece of 10th street?).

Hi-viz clothing and safety

cycle-outfits-ian-walker-researchThe drumbeat to encourage bicyclists to always wear “hi-viz” (hi-vis, high-visibility, fluorescent) colored clothing — even in daylight — seems to become louder and louder. But it appears there is scant evidence suggesting any measurable safety improvement. The best I get when asking what evidence exists is something along the lines of “it can’t hurt”. (this has echos of the never-ending helmet wars; helmet’s claimed safety improvements have been overstated, sometimes vastly, over the years) Continue reading Hi-viz clothing and safety

35% drop in AZ traffic tickets

If ~ $250 sounds like a lot of money for a civil traffic infractions — learn where all that money goes. Most of it does NOT inure to the city which issues the ticket. Cities only get a small fraction of the ~ $250.  The rest of the money goes to state-levied “surcharges” that fund all sort of law-enforcement-related programs. This give lie to the myth that cities are getting fat off of enforcement in AZ; see revenue-from-traffic-fines for some examples, e.g. city of Phoenix generates about 1% of it’s budget from traffic fines. Continue reading 35% drop in AZ traffic tickets

Slow by nature

slowMovingVehiclesCollageAlthough the vast majority of vehicles are driven at the “normal speed of traffic” — there are many classes of vehicle (or device) which are by their nature sometimes or always driven at less than the normal speed of traffic, yet are generally allowed on the roadway. These include both motorized and non-motorized vehicles. Operation of these vehicles/devices is allowed unless specifically prohibited; for example bicyclists and motor-driven cycles are not permitted in the roadway on limited access highways. They can also be prohibited by minimum speed limits, however as noted here, there are few if any minimum limits established anywhere in AZ.

Besides bicycles, there are many classes of vehicle permitted on any street in Arizona with limitations as noted, these are just examples, there are probably others: Continue reading Slow by nature
