BEST PRACTICE:

C2−2: Modeling Projected Traffic Delay

DESCRIPTION:

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.

PRIMARY BENEFIT(S):

Complex traffic redistributions are made more comprehensible in planning for traffic changes required by project construction.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Type of Facility: Freeways, streets, 2−lane/2−way highway, and bridge.
Location: Urban, rural, and recreational.
Volume/Speed: High−volume/high−speed, high−volume/low−speed, low−volume/high−speed, low−volume/low−speed.
Type of Work: Resurfacing, reconstruction, restoration/rehabilitation, and utility.

STATE(S) WHERE UTILIZED:

Massachusetts
