Toddler killed in Tempe parking lot

ped fatality in apt complex; victim 3 yo girl.  Occurred in the parking lot of apartment complex near University Drive and Rural Road around 2 p.m. June 25, 2018

It’s been widely noted that AZ has a growing and worsening ped traffic fatality “problem”; fortunately this one doesn’t count (yes, this is sarcasm, but nevertheless true)… because it happened in a private lot, it’s non-traffic and as such doesn’t count as a traffic fatality; DUI or otherwise. (similar to e.g. little Daylin Garcia Enos who was killed in a Tucson apt complex parking lot by a backing UPS truck)

ASU doctoral student killed in Tempe crosswalk crash

“Left Cross” collision

[ 1/29/2018 City of Tempe is considering changing cyclist right-of-way rules. This is potentially very involved and intricate. See both below, and also see letter and replies from Councilman Keating sent as CAZBike ]

[ 11/24 Updates on this shocking crosswalk fatality continue to ooze out from Tempe police, as the grieving family of Xiaoying Wen came to Tempe from China seeking answers; “Tempe police said both had the green light, but Wen failed to yield, and Tempe city law dictates that bicyclists must yield to motorists”. See below for this bad local law. LAB Bike Friendly GOLD? ]

The 11/21 News story says the crash occurred ‘last week” ? news media seems to report less and less.
Date:  [Thursday 11/16/2017 ~ 4:15pm per comment below] Location: intersection of Rural Road and Vista del Cerro Drive

Tempe Traffic Collisions

There have been 4 bicyclists killed in Tempe traffic collisions on city streets (excludes limited-access highways) over the past 5 years [five year period 2010-2014); at the same time dozens of motorists and 14 pedestrians have been killed.

[UPDATE: There were zero bicyclist fatalities in 2009, and 2015; there was one in 2016, and one in 2017 (as of December). I.e. there have been a total of 6 bicyclist traffic fatalities in the past 9 years]

Scope of the Problem

For the figures in this report, a 5-year time period, 2010-2014 was selected (the most recent available at the time; 2015 & 16 has since become available). Many additional crashes occur (14,000!) occur in Tempe on limited access highways; these crashes are not included.

There were 21,167 traffic crashes reported in the period, below are the number of people, by person type, involved: Continue reading Tempe Traffic Collisions

This happened one day in Tempe

northbound Hardy near University Drive. Could a bus driver safely overtake a cyclist here? Could a bus driver safely overtake 50 bicyclists here? Should a bus driver attempt to overtake 50 cyclists here?

Out for a Saturday morning group ride on Hardy Drive in Tempe July 2, 2016, cyclists had some sort of negative encounter with a motorist. Traffic would be light at 9AM on a Saturday morning in the dead of summer, except for the group of estimated 50 bicyclists (dispersed, not one group) and that motorist. The street here is very narrow, is traffic-calmed with ped islands and speed tables installed in a 2014/15 streetscape project, and has a speed limit of 30mph.

Warner Resurfacing

Warner Road; typical cross section ~ 68 feet curb-to-curb (google maps sat view before 2016 resurface)

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

Usable Width and Bike Lanes

[Jump directly below to Usable Width for roads without bike lanes]
[Jump directly below to Guadalupe Rd resurfacing example]
[Jump directly below to some engineering details of gutter pans]

Usable Width of a Bike Lane

These Bike Lanes meet both the minimum overall width and recommended usable width

The dimension below all refer to urban streets with curbs and no parking…  Most recommendations for Bike Lane dimensions refer to the AASHTO Guide for the Development of Bicycle Facilities , the general rule is

the minimum bike lane width is 5 ft (1.5 m), measured from the face of a curb or vertical surface to the center of the bike lane line

However, that changes when a gutter pan is involved, more width is required to meet their recommendations —

Along sections of roadway with curb and gutter, a usable width of 4 ft (1.2 m) measured from the longitudinal joint to the center of the bike lane line is recommended

Hardy Drive Streetscape project

new ped refuge island; Hardy Drive, Tempe

The Hardy Drive Streetscape project re-did this 30mph posted, low-speed collector street between University Dr. and Broadway Rd, more specifically, the project only affected bicycle infrastructure between 9th and 19th Street,  a distance of about 9/10ths of a mile. [google maps] The project was completed in early 2015 about the same time as the the University Drive Streetscape Project. Continue reading Hardy Drive Streetscape project

University Drive textured Bike Lane


[update Jan 2018: the project area has been resurfaced (already? why?) see below]
The project area is University Drive between east of Priest Dr and Farmer Ave [correction: it’s actually Ash, a few hundred feet further east; i did not update the crash history, below; i don’t think it would change much]. There are other aspects of the project I like very much, e.g. the new raised medians. These should make the road safer for all users. The speed limit is still posted at 40mph, I encourage the city to lower the limit to 35mph, which would make the road even safer for everyone.

In a nutshell, the problem is the City placed 2′ of texturing in a 6′ bike lane, leaving only 2.5′ of usable surface (the gutter pan is the remaining 1.5′). I have a photo gallery (or most of same pics on a public facebook album) of some of the issues revolving around the texture in the bike lane.

Should Warner Road bike lane have a “Combined” Turn Lane?

A standard sign with placard, “legalizes” thru-bike usage.

it is a common occurrence — familiar to every bicyclist — where you can be riding along a perfectly nice bike lane only to have it disappear for various reasons.

Bike lanes are highly prized for making cycling “more comfortable”; so I think it’s safe to say disappearing bike lanes would be considered quite stressful, and an impediment to cycling for many cyclists.

Disappearing Bike Lane; Warner Rd at Hardy Dr, Tempe, AZ

I have, over the past year, had occasion to regularly ride along Warner Road in Tempe (this area is sometimes referred to as “south” Tempe. Here’s a map of the general vicinity) between I-10 (the city limit) and McClintock Drive; it’s about 3.5 miles. The road is very much an arterial road with two fast through lanes (45mph, if i recall correctly) plus a bike lane each way plus some sort of middle lane throughout (it’s usually a TWLTL; two way left turn lane; it becomes a left turn lane at major intersections). The difficulty is at every intersection where there is a right turn only lane, the bike lane is dropped ~ 250′ from the intersection. This dropping occurs asymmetrically at some, but not all, of the major intersections. It is most prominent westbound: the lane drops at McClintock, Rural, Kyrene, Hardy, and Priest Drive. That is FIVE TIMES in three miles! Continue reading Should Warner Road bike lane have a “Combined” Turn Lane?
