TRAFFIC ANALYSIS RESULTS
• Traffic Models• Lower Mystic Regional Working Group• Tt
• Synchro is a macroscopic analysis and optimization software program for signalized intersections, unsignalized intersections and roundabouts. Allows modeling of individual intersections, corridors or grid networks.
• SimTraffic is a microscopic model where each vehicle in the traffic network is individually tracked through the model and comprehensive operational measures of effectiveness (MOEs) are collected on every vehicle during each 0.1-second of the simulation.

TRAFFIC ANALYSIS RESULTS
• PEDESTRIAN & BICYCLES• Both Alternatives would have safe facilities
• Underpass Alternative has shorter Intersection Cycle Lengths• Pedestrian crossing at Underpass ramps is limited• Several New Crossing Points added
• Signals will have LPI (advanced walk)• Countdown pedestrian heads, APS pushbuttons (Advanced ADA)
• Separated Bike Lanes – both sides of corridor• Bike signal indications and Bike LBI
