GIS Tools For Assessing Bicycle Suitability Training Video April 2012 Mike Lowry Civil Engineering University of Idaho
Training Video Outline 1.Background 2.How to use the new tools 3.How to enter your community’s data
ITD Statewide Customer Satisfaction Survey 75% of respondents: safe biking is important
Project Goal: Create GIS tools to assess comfort and safety of bicycling. Purpose and Scope: To help engineers and planners prioritize improvement projects.
Final Report GIS Tools -Source code -Help files -Example data
Bicycle Suitability Perceived comfort and safety of a linear section of bikeway (streets and shared-use paths) Bikeability Perceived comfort, safety, and convenience of an entire bikeway network to access important destinations (community-wide) Bicycle Friendliness General perceptions about all aspects of bicycle travel, including bikeability, laws and policies to promote biking, education efforts to encourage biking, and general acceptance of bicycling throughout the community

[The next section of the video uses ArcGIS. The following slides outline the material.]
Introduction Look at files using Explorer Look at files using Catalog Look at Example Files in Catalog BLOS Tool Pull in Streets. Open attribute table. Look at Interface and Help for Calculate BLOS Execute Calculate BLOS Look at new output attribute table BSL and BSS Tools Execute Calculate BSL. Execute Calculate BSS.
Other BLOS Tools Execute Calculate BLOS again, comment on warning for already existing fields Look at other BLOS tools Return to powerpoint
Street Intersection Travel Direction Facility
BLOS Tools Execute Calculate BLOS Intersection Execute Calculate BLOS Facility Comment on Data Preparation Tools Execute Create Intersection File, Open Attribute Table Pull in Pathways Execute Calculate BLOS Pathway Bikeability Explanation Pull in GroceryStore_destinations Review the concept of Bikeability Execute Append for Pathways to Streets and call it bikeways.
Bikeability Tool Pull in Zones. Pull in grocery store destinations and explain. Execute Calculate Community-wide Bikeabilty for existing grocery stores. Pause because takes 6 (5.5) minutes on my laptop computer. The report discusses execution times for different zone sizes. Return to ArcGIS. Look at last few seconds and explain what is happening. Look at results. Discuss good bikeability areas. Execute again for proposed grocery store.
Scenario 1: Existing Grocery Stores Scenario 2: With New Grocery Store
Scenario 1: Without New Bike Path Scenario 2: New Bike Path
[Return to ArcGIS.]
Bikeability Tools Pull in, open, and look at parcel file, but don’t Execute. Execute Identify Probable Routes to a Destination Jr. High school using zones. Execute Identify Probable Routes to a Destination Jr. High school using student addresses. Statistic Tool Execute Statistic tool for all three.
Create Zones Tool Execute Create Analysis Zones. Note that smaller zones will require more time. Create Streets File Execute Create Streets File Look at blank attribute table. Note street class Look at streets that are “isolated” or outside of study area
Correct Topology Incorrect Topology
[Go to arcgis.com help. Search “Topology”, look at “Topology basics.” Explain. Search “Topology errors”, look at “Geodatabase topology rules and…”. Explain there are few existing tools to help create topology. Return to powerpoint to show Create Street File.]
Enter Data Look at table in excel. Execute Enter Data and look at output.
