lane-splitting is lane-sharing

This is still in quite rough form. Bear with me as I elaborate. The premise is (motorcycle) lane-splitting is related to (bicycle) lane sharing.

Lane splitting Legal Misconception

Note that the motorcyclist is NOT driving on the lane line

I was under the impression, what I believe now to be a common misconception, that motorcycle lane-splitting refers to a motorcyclists splitting between two lanes; in other words riding on the dashed line.

There are two related traffic rules, the first is general and applies to all persons driving any vehicle: motorcyclists, motorists driving cars/trucks, and incidentally also to bicyclists. This general rule implicitly makes lane-splitting by riding on the dashed line illegal. Continue reading lane-splitting is lane-sharing

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.

Two “missing” 2015 hit-and-run fatalities

I found these two only because they appear in asdm data for 2015. I find nothing googling. Given the paucity of data and the profusion of UNKNOWNs these two appear to simply have the hit-and-run flag mis-coded?? These both have absolutely no location information, i.e. no streets, and no Lat/long. Continue reading Two “missing” 2015 hit-and-run fatalities

Arizona’s “Truth in Sentencing” Law

I feel like I’ve looked this up before.

Arizona passed a major overhaul to the state’s sentencing code (Senate Bill 1049, Chapter 255, 1993 laws) in the 1993 legislative session. Annoyingly, the online lookup doesn’t go back before 1997, so at the moment I don’t have access to the bill itself. (need to look it up thru library). Continue reading Arizona’s “Truth in Sentencing” Law

Alternative Transportation advocate Steve Schmitt passes away

This is mainly of interest to me as the organization Steve was director of since 1994, the Coalition for Appropriate Transportation, is my hometown of Bethlehem, PA. Although I never met Steve, his work at improving transit, walking, and bicycling are significant. I had moved away from Bethlehem for work once I graduated from college in 1983, so we didn’t really overlap in time. I had tried to meet up with him a few years ago during a visit but we weren’t able to sync up schedules. Continue reading Alternative Transportation advocate Steve Schmitt passes away

Adot Bicycle Facility Design Workshop

IMG_20141120_094433068_01IMG_20141120_155140430_01Attended an all-day Bicycle Facility Design Workshop  on Nov 20, 2014. Thanks to Mike Sanders and ADOT for putting this on.

The class was very well attended, with perhaps 40 students from all around the state; mostly either various adot personnel, or planner-types working for cities. (and the class was offered twice, and the other session was filled to capacity also).

The instructors, Mike Colety and Steward Robertson, both of Kimberly Horn Assoc,  were very knowledgeable with the subject matter, and cycling in general — if i recall correctly, it was mentioned they were both LCI’s.

The material hews very closely (or possibly, completely)  to the AASHTO Guide for the Development of Bicycle Facilities.
