CORRIDOR INFORMATION
Community FeedbackWhat we have heard!
• Delivery operations should have places to load/unload so they don’t use the bike lanes
• Prevent motorists from using bike lanes to load/unload
• Relocate MIT tour buses loading/unloading
• Bicyclists should be further separated from vehicles
• There are long vehicle queues, lots of traffic at Vassar Street
• Minimize conflicts, including bus/bike conflicts and bike/ped conflicts at 77 Mass Ave.
• Install more crosswalks between Sidney St and Landsdowne St

CORRIDOR INFORMATION
Transportation/Traffic Analysis
• Corridor-wide transportation analysis to determine where:
• Bus lanes can be added• Crosswalk can be added• Vehicle lanes can be repurposed• Signal operations can be modified
• Manage traffic• Mitigate conflicts
• Bicycle lanes can be separated• Bicycle buffers can be added• Parking/curbside activities can be modified for
better operations• Loading Zones• Pick-up/Drop-off activities• Accessible spaces

Design Analysis
Mass. Ave
Alternative 1: 3-lane cross section• more turning conflicts for people
walking or bicycling• traffic better in off peak, worse
in peak, including buses
Alternative 2: 4-lane Cross Section• Key conflicts controlled for people
walking, bicycling• AM peak performs better, PM is
worse
