• MBTA’s Service Delivery Policydefines acceptable levels of crowding by time period and transportation mode
• “For bus, on weekdays the loads cannot exceed the standard when averaged over any 30-minute segment of an Early AM, AM Peak, Midday School or PM Peak period, or any 60-minute segment of a Midday Base, Evening, Late Evening, or Night/Sunrise period.”
TransitMaximum Passenger Loading
January 26, 2016| www.mass.gov/massdot 15
• For bus routes 70/70A along the Arsenal Street Corridor:• Max acceptable load = 54

TrafficStudy Area Intersections
January 26, 2016| www.mass.gov/massdot 20
TrafficSignal Inventory• Reviewed 14 signalized study
area intersections
• Issues were noted at all locations, including:• MUTCD Compliance – Non-conforming
pedestrian signal head type, push button placement, pedestrian signal operations, etc.
• ADA Compliance –Push button type, lack of pedestrian accommodations, etc.
• Operational/Maintenance Issues – Vehicle recall, detection, controller clock off (time of day, daylight savings), coordination issues, etc.
• Safety Deficiencies – Pedestrian signal phasing, pedestrian-vehicle and vehicle-vehicle conflicts.
• Deficiencies will be reviewed and short-and long-term solutions (as applicable) will be identified
