KBOO Bike Show: Cyclocross

 Listen to the show (mp3, 26.1MB)

This month the Bike Show explores the life cycle of Cyclocross in the United States. From the birth of cyclocross in the 70’s, we speak with Laurence Malone– a.k.a. The Godfather of Cyclocross racing– about the sport’s humble origins in the us and what it was like to be the lone American on the starting line overseas in the early years.

We’re also be joined by current pro Ryan Trebon of the Cannondale Cyclocross World Team and recently retired and 2013 Cyclocross World Masters Champion Sue Butler about how the sport of ‘cross has (or hasn’t) grown in the ensuing years.

Bikes Have a Level of Service Too!

PSU Transportation Seminar

Speaker: Nick Foster, Senior Planner, Kittelson and Associates
Topic:  Evaluating the Level-of-Service of Protected Bike Lanes
When: Friday, November 21, 12:00pm to 1:00pm

Where: PSU Urban Center Building, SW 6th and Mill, Room 204

Summary: The most recent edition of the Highway Capacity Manual (HCM) contains analysis procedures for measuring the level-of-service (LOS), also referred to as quality of service, provided by an urban roadway to bicyclists. The method uses different design and operating features of the roadway segment (e.g. width, motor vehicle volumes and speeds) to assess an LOS grade of A (best) to F (worst). These procedures are used by planners and engineers to recommend how existing streets could be retrofitted or new streets designed to better serve people on bicycles (and other modes). However, the current HCM does not include methods that address protected bike lanes (aka “cycle tracks” or “separated bike lanes”), only conventional striped bike lanes, shoulders, and shared streets. There are other methods for predicting comfort from a bicyclist’s perspective that do consider protected bike lanes, but they are either based only on expert opinion or on surveys in Denmark.
 
This presentation will describe how to evaluate the level-of-service of a protected bike lane using results from surveys conducted in the United States. The model developed by this project could be used to supplement the current HCM to objectively consider a wider range of options for improving the environment for bicycling. This is increasingly important as the implementation of, and demand for, protected bike lanes surges around the US.

KBOO Bike Show: Activism for our Streets

 Listen to the show (mp3, 25.5MB)

This month we go back to our roots– grass roots that is. Portland’s flame of cycling activism burned out over the recession. But recently, out of the ashes comes new, exciting growth. Tori and Chris talk with Alex Reed of Bike Loud Portland, Lisa White of Bike-Walk-Vote and Boris Kaganovich of Better Block PDX. These passionate and motivated average-citizens are shaping the way your city streets look with an energy and enthusiasm not seen since we ripped out a highway and replaced it with a park.

What Makes a Friendly Street?

PSU Transportation Seminar:

Impact of Route-Level Features on Decisions to Walk or Bike

Speaker: Joseph Broach, Portland State University
Topic: Impact of Route-Level Features on Decisions to Walk or Bike
When: Friday, October 31, 2014, 12-1 pm
Where: PSU Urban Center Building, SW 6th and Mill, Room 204

Summary: Some travel routes attract people walking and cycling, while others may scare them away. What features of street environments are most important, and how do available routes affect decisions to bike or walk on a specific trip?

Research to date has focused on either large-scale areal measures like “miles of bike lane nearby” or else has considered only shortest path routes. Neither method is suited to capturing the impact of targeted route-level policies like neighborhood greenways. This session will present a new technique for measuring bike and walk accessibility along the most likely route for a given trip. The method is applied to travel data, and results provide new insight into the relationship between route quality and travel mode choice.
