Goals

Project Goals, Objectives, and Evaluation Criteria

To guide the outcome of the study toward a defined resolution, the study participants cooperatively developed three project goals and four project objectives. These goals provide guidance toward the development and evaluation of alternatives. The use of this structure helps to maintain a clear purpose while conducting the analysis and clarifies why decisions are made during the course of the project. In addition, the goals prove valuable in later stages for the development of the recommendations.

GOALS

  • Increase the regional accessibility of Boston's Back Bay with I-93, the Seaport District and Logan Airport. By better connecting these sections of Boston, the hotels, other businesses, and residential areas of Back Bay would by tied more closely with Boston's new convention center, world trade center, marine facilities, and Logan Airport, New England's International gateway.
  • Provide new access to the regional express highway system for Boston's Fenway and Longwood Medical Area to better connect with I-93, the Seaport District, and Logan Airport.
  • Ensure that any transportation improvements are sensitive to the concerns of neighborhoods within the study area (Back Bay, Bay Village, Brighton, Brookline, Cambridge, Chinatown, Fenway, Longwood Medical Area, and South End).

OBJECTIVES

The project objectives provide a definitive aim to achieve the goals.

  • Study potential new or revised eastbound-on or westbound-off ramps along the Massachusetts Turnpike that would directly serve Boston's Back Bay.
  • Study potential new or revised eastbound-on or westbound-off ramps along the Massachusetts Turnpike that would directly serve Boston's Fenway and Longwood Medical Area.
  • Ensure that any potential new or revised Massachusetts Turnpike ramps do not negatively impact the existing operations along the Turnpike.
  • Ensure that traffic pattern changes caused by new ramps along the Massachusetts Turnpike reduce the traffic volumes along key arterials that travel through adjacent neighborhoods connecting to the Back Bay, Fenway, and Longwood Medical Area.

EVALUATION CRITERIA

The evaluation criteria are specific considerations that evaluate benefits and impacts of alternatives developed during the study. These criteria will assure that recommended transportation improvements provide a sound investment of public transportation funds and that any adverse effects in the study area are minimized.

  • Traffic Congestion Level of Service, queue delays
  • Motorized Circulation and Access Travel times, vehicle route continuity, directness, connectivity
  • Transit and Non-Motorized Circulation and Access Bicycle and pedestrian access; changes in access for transit passengers, physical impacts to proposed transit
  • Safety Vehicle crashes, changes in pedestrian and bicycle route separation, changes in emergency vehicle access
  • Neighborhood Impacts Noise; cut-through traffic, aesthetics, neighborhood cohesion
  • Environmental Impacts Air quality, wetlands, hazardous materials, archaeological and historic sites, parks and open spaces
  • Business Considerations Access to existing and future development parcels, physical impacts to development, parking for customers, truck circulation and access
  • Cost and Schedule Total construction cost and timeframe
