  Project Data

The objective of this research was to develop a guide for analyzing and quantifying the impacts of traffic incidents and the economic benefits of TIM strategies. The guide is to be used by TIM program mid-level managers/analysts in planning and operations for a broad spectrum of transportation and incident responding agencies with varying TIM program maturity levels and a variety of data collection capabilities.
The Highway Capacity Manual 2010 (HCM 2010) included capacity reduction estimates due to lane blockages on freeways. There was a need for this information to also be validated with new data considering various road and traffic conditions. Also, there was a need for determining reduction in capacity estimates for other types of roadways to improve accuracy and application of TIM related analytical procedures.
STATUS: Research is complete. The guide is available as NCHRP Report 981 and the conduct of research report as Web-Only Document 301 at https://www.trb.org/Main/Blurbs/182580.aspx.
