• Four lane Vilas Road scenarios not feasible • Two lane Vilas Road scenarios only feasible for “familiar drivers” where
reaction distance = 0 feet. THEREFORE 400 feet is NOT sufficient to accommodate necessary
• Acceleration • Reaction distance • Legal turn signal distance of 100’ required by the OR Vehicle Code • Deceleration

Conclusions
51
Summary • No mitigation = extensive queueing and congestion throughout the network
• Roundabout and 2-Lane Vilas Rd Scenarios are NOT VIABLE
• No Build – JTA Build, 2-lane Vilas Rd, Tier 2 Projects • Lowest crash frequency • Shortest overall network travel time • Low intersection and turning bay blocking
• Build – Full Build, 4-lane Vilas Rd, Tier 2 Projects
Assume completion of intersection mitigations used in analysis
