• Abstract:
  Freight delay is detrimental to the national economy. In an effort to gauge the economic impact of freight delay due ; to highway congestion, this project focuses on estimating shippers’ value of delay (VOD). We have accomplished ; this through three strategies to monetize the impacts of congestion on shippers’ operations: ; • Three half-structured on-site interviews with shipping managers in different type of industries were ; conducted to obtain insights into their daily logistic operations and their subjective assessment of the delay ; impacts. In light of the interviews, a comprehensive survey of major manufacturers and wholesalers within ; Texas and Wisconsin was conducted. ; • The analytical hierarchy process (AHP) and willingness-to-pay (WTP) method were then applied to ; quantify the impact of congestion on shippers. The AHP reveals that among four possible delay ; components, en route transportation delay is the most important, which justifies WTP evaluating the value ; of highway congestion delay. We have found a value of $56 per hour for congestion. Furthermore, a value ; of $0.4 per percentage delay was also calculated for transportation time reliability using individual defined ; travel time. ; • An analytical inventory model was used to examine the value of delay in view of mean and reliability of ; transit time for shipment receivers. Nine industrial groups were analyzed. For example, shippers in the ; chemical industry are calculated to have an additional $13.89 cost on a truckload delivery if the transit time ; is expected to increase by one hour. The random delay has an average of $31.04 per hour per truckload ; delivery.
