Early Action Plan: InterimImprovements
Early Action - Interim Improvements
Goal: Identify short-term roadwayimprovements that could be accommodatedwithin the existing curb lines
Design Completion: Spring 2015Estimated Construction Period: JulyDecember 2015Include utility work in Prospect Street
Prospect Street: Sewer & WaterNew sewer and water mainto serve MBTA station andD2 developmentNew fire hydrants
Improve Traffic Flow & Safety at SignalizedIntersections
Reduce Overall Intersection DelayReduce Circuitous Traffic Movements
• One-Way vs. Two-Way Webster + Prospect
Evaluate Turn Lanes at Intersections
Goals of Interim TransportationImprovements
Goals of Interim TransportationImprovements
Improve Pedestrian ConnectivitySignal Timing/Phasing
• Exclusive vs. Concurrent Phasing• Leading Pedestrian Interval
Goals of Interim TransportationImprovements
Improve Pedestrian ConnectivityCrosswalk Locations
• Shorten CrosswalkLocations where Possible
– Modify Alignment– Adding Bump-out
• Add any MissingPedestrian Links
Improve BicycleConnectivity
Painted Bicycle Lanes
Bike Boxes• Increase Visibility of Cyclist• Reduces Signal Delay• Facilities Left Turn Position• Helps Prevent Left Hook
Conflicts
Goals of Interim TransportationImprovements
Improve Bicycle ConnectivityTwo Stage Turn Queue Box
• Left Turn Safety• Formal Queue Space• Reduces Turning conflicts• Separates Turning &
Thru Bicyclists
Goals of Interim TransportationImprovements
