1 Twin Cities Bicycle Barriers Study Technical Advisory Work Group December 19, 2016

2 Regional Bicycle Barriers Overall Study Area Parameters Specific Barrier Parameters Rivers & streams Rail corridors

3 Overall Study Analysis Generally, focus on barriers within RBTN coverage area Analyze only barrier segments that have bicycle facilities w/in one half-mile on both sides of the barrier

20 Railway Corridors Change in Analysis for Rail Corridors Initially, no at-grade public roadway crossings were included in analysis Now, at-grade rail crossings on A-minors & collector roadways will be analyzed as potential improvement locations

21 Defining Expressways: A New Approach

22 Expressways: Take 1 (last TAWG) Four-lane divided highway segments Posted speeds of 45 mph or greater Traffic signals at least 1 mile apart

23 Expressways: Take 2 (dropbox review version) Four-lane divided highway segments Posted speeds of mph or greater Traffic signal spacing of at least 1 mile

24 D) Regional Barriers & Study Parameters STUDY AREA Freeways & Expressways

25 New Approach: Start with Principal Arterials from Met Council s Functional Class System map which includes: Interstates Other freeways Expressways Some county roads not expressways (2 lanes or not divided arterials)

Edge Emerging Suburb Edge, Rural, Rural Center 1.5 miles 3 miles 2 nd ring sub s, Blaine, Woodbury, Maple Grove, Eagan, Lakeville Hastings, Rosemount, L. Elmo, Forest Lake

45 1. Planned bikeway crossings 2. Non-bikeway minor arterials & collector roadways 3. Existing ped bridges (w/o ramps) 4. Additional points needed to fill in crossing voids along barrier segments that: Align w/dead-end roads (culs-de-sac) Take advantage of parallel roads on either side Match up with noted cow paths

47 FACTOR TALLIES Connectivity 15 Demand 14 Safety 9 Equity 7 Existing Conditions (e.g. roadway characteristics) 5 Stakeholder Input 3 Constraints (e.g. cost, ROW) 3 Opportunities (e.g. upcoming projects) 3 Write-in: Barriers identified in locally adopted plan 1 Compliance 0

48 Targeted Focus Groups: 1. General cycling focus group Review regional barriers map, preferred spacing of barrier crossings, crossing evaluation factors and factor weights 2. Underrepresented populations focus group Review analysis factors, data & their application relative to equity Consider other (non-infrastructure) barriers to cycling

49 1. Develop focus group session invite lists, questions, logistics 2. Review available datasets, determine list of viable measures 3. Refine regional barrier maps for focus groups 4. Develop/Initiate project web page 5. Conduct focus groups late Jan. to early Feb. 6. Next TAWG in February
