C2−2: Modeling Projected Traffic Delay
A computerized traffic model (TRANPLAN) was developed during preparation of a project's environmental impact statement. This model has been upgraded and refined to support final design and construction.
REASON(S) FOR ADOPTING:
Project construction required changes and impacts to I−93, I−90, and five separate geographic neighborhoods in the City of Boston. Many of these traffic impacts involved complex redistribution of vehicles. The TRANPLAN model helped clarify potential traffic impacts.
Complex traffic redistributions are made more comprehensible in planning for traffic changes required by project construction.
