Re: Alameda Drive Streetscape Proposal
The City of Tempe is considering various treatments along Alameda Drive; one section of which, between RR tracks and Rural Road is primarily residential and currently has no bicycling-specific striping or pavement markings.
When selecting please refrain from placing designated bike lanes withing the door zone of parked vehicles; in particular, Residential “Alt A” shows such treatment with the right-hand edge of the bike lane only 7 feet from the curb which places the entire width of the (very narrow, at 4′) bike lane within a hazard-zone. This places bicyclists in the uncomfortable position of needing to ride away from door zones to remain safe from door hazards and will end up riding in what is noted in the proposal as a buffer zone, which is next to a very narrow (10′) travel lane. The double-yellow dividing line will discourage motorists from providing the required 3′ minimum safe clearance (a requirement that Tempe police, by the way, do not “believe in”, see #6 here).

Cutting into a road surface creates maintenance problems. Since the city is ultimately responsible for it, there are a set of rules, permits, and fees imposed on whomever might be doing the digging, typically an adjoining property owner (for, for example a new driveway) or utility companies, or the city itself (see example photo at right).
The aftermath of any cutting or digging in a road is particularly problematical for bicyclists when it results in longitudinal gashes/gaps/cracks… and is particularly problematical when the crack is within a Bike Lane because it can reduce the usable width to the point where traveling within the BL becomes impossible to do safely; and furthermore these dangerous conditions are unlikely to be appreciated or even noticed by motorists.

Thanks to the City of Tempe Streets Dept for contacting me/us about this project. A one mile section of Mill Avenue, from Broadway Road to Southern Avenue, is set to be resurfaced (they call this a “Pavement Preservation”) soon, I think Summer/Fall 2017.
This section has edge lines enclosing a small shoulder. (“fake bike lane”). Edge lines generally should not be used on urban arterial roads in this configuration; and especially when they look like bike lanes, and thus are easily confused with bike lanes. The picture of the grate, in the shoulder should be self-explanatory.
Warner Road is a major east-west arterial that runs through much of the East Valley. It’s continuous from Phoenix (Ahwatukee area, where it forms a loop with Elliot Road, another major e-w arterial), thru Tempe, Mesa, Gilbert. In the city of Tempe it runs the entire width of the city, from wherever exactly it is that Tempe begins (just east of I-10 bridge) to just west of SR101 (google maps)
Warner in this area generally has two through lanes and a designated bike lane (BL) in each direction as well as a continuous center lane, some major intersections have right-turn-only lanes (RTOL), but others do not (more on that later). There are no BLs in the area immediately east of I-10, and there are numerous “dropped” BLs; where the BL is intentionally discontinued to make room for a RTOL. Continue reading Warner Resurfacing→
In mid December 2016 Sfbike.org (SanFrancisco Bike Coaltion) issued a warning regarding how Uber autonomously driving cars make right turns. At nearly the same time Uber has de-camped from CA (see e.g. this 12/22/2016 article from recode), literally loading their fleet onto car carriers and driving them to…. Arizona! The decision was based on CA’s regulatory environment for autonomously-driven cars; Uber decided they didn’t want to pursue special permitting which the CA DMV said was required, whereas Arizona has no special permitting required — so long as there’s a live driver sitting in the driver’s seat. More about Uber, below. Continue reading How to make a right turn→
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?). Continue reading City of Tempe tests ‘Bike Box’→
When the final portion of the Loop 202 / South Mountain Freeway (SMF), the part that connects I-10 to Laveen, gets constructed it will replace Pecos Road. Pecos Road in Ahwatukee will be no more. This would otherwise leave everything west of 19th Avenue inaccessible from the rest of Ahwautkee, except for the freeway. The construction of SMF is supposed to begin summer 2016 and opens late 2019. Continue reading Chandler Boulevard Extension→
For background on the SLM (Shared Lane Markings, a.k.a. sharrows) on the phoenix-side, see here, and more pictures here. That first link has an explanation as to why this bridge is an important and useful link for bicyclists. Continue reading Guadalupe and I-10 Bridge→
