Steele St

Multimodal Safety Project

July 10th, th, 2019

HOW? Provide roadway

space for all

WHY? SAFETY

Trend is going up in 2019 – Streets need to be designed to be safer

Project Background

Corridor in Context

• Corridor provides regional connection
• Steele St is inherently high-comfort
• Intersections of E Alameda Ave and E Exposition

represent challenging crossings

• History of crashes/speeding on Alameda

S University Blvd (5-lanes) S Colorado Blvd (8-lanes) ~1-MILE

STRAVA METRO DATA

More than a Decade in the Making

Late 2000s

Why? Community Priority

CCD Uncontrolled Ped Crossing Guidelines requires 20 bikes/peds per hour threshold to be met for consideration of a marked crossing; Steele St and Alameda Ave recorded 37 bicyclists and pedestrians in the peak hour; Steele St and E Exposition Ave recorded 31 bicyclist and pedestrians in the peak hour

Steele and Alameda

Complex vs Simple Intersections

Steele and Alameda

Existing Intersection Issues

• No marked crosswalk
• Long crossing distances
• Poor intersection design
• Poor site lines
• Fast turning vehicles
• History of crashes/speeding

72’ 73’ 63’ 76’ Long Crossing Distances

Angled curb ramps lead into intersection

Poor site lines – due to setback stop bars Stop Bar Stop Bar

Large Turn Radius ~80’ @ 20mph

Unpredictable turning movements

5 Crashes @ Intersection

Speed Kills

The speed limit on Alameda Dr is 25 mph, but the majority of drivers westbound travel faster than 30 mph. If a pedestrian is struck by a car travelling that speed, they have 40% chance

• f dying or having a life-

altering serious injury.

2017 Bicyclist Crash

Driver Quote: "THE SUN WAS IN MY EYES AND I COULDN'T SEE, I SAW A

CAR COMING AND I TRIED TO BEAT IT, I TURNED AND I TOOK IT REALLY

• SHALLOW. BY THE TIME I SAW THE BIKE IT WAS TWO FEET IN FRONT OF ME.”

“THE SUN WAS IN MY EYES AND I COULDN'T SEE”

• Design Solution – place queuing bicyclists and pedestrians in protected area

“I SAW A CAR COMING AND I TRIED TO BEAT IT, I TURNED AND I TOOK IT REALLY SHALLOW.”

• Design Solution – articulate turning movement so “taking it really shallow”

and trying to “beat [on-coming vehicles]” is not a viable turning movement “BY THE TIME I SAW THE BIKE IT WAS TWO FEET IN FRONT OF ME.”

• Design Solution – mark crosswalk to increase motorist awareness of crossing

bicyclists and pedestrians

Centralized Crossing Diverter

Presented April/May 2019

What we heard:

DO:

• Provide a safe crossing for

pedestrians and bicyclists

• Make turning movements at

intersection more predictable DON’T:

• Restrict turning movements
• Impact the center turn lane in front of

the Polo Club Condos

• Impact loading operations in front of

the Polo Club Condos

• Increase congestion
• Impede emergency vehicle movements
