C1−4: QuickZone Impact Analysis Spreadsheet Tool

DESCRIPTION:

QuickZone is a work zone delay impact analysis spreadsheet tool developed by FHWA. QuickZone is an open−source, Excel−based application able to quantify corridor delay resulting from the reduced capacity in work zones; identify impacts of alternative construction phasing; assess the impacts of delay mitigation strategies; and support the calculation of work zone completion incentives/disincentives.

During the roll−out of this spreadsheet, FHWA partnered with States and local transportation agencies to facilitate the initial set−up of the spreadsheet for the agency's needs. One of the QuickZone partners, the Maryland State Highway Administration (MDSHA) was interested in building upon the existing code available in QuickZone, particularly when assessing the impacts of alternative construction phasing. MDSHA customized the software with a State−specific capacity estimation model and uses it to prepare for work zone activities across the State. A number of other States use QuickZone as one of their tools for work zone traffic analysis.

REASON(S) FOR ADOPTING:

To assess the impacts of alternative construction and maintenance of traffic approaches.

PRIMARY BENEFIT(S):

Allows users to calculate the cost of traveler delay on a corridor level.

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

Any State or locality interested in quantifying delay resulting from work zones.

STATE(S) WHERE USED:

Maryland
