65 C H A P T E R 6 6.1 Private and Public Costs of Inefficient OSOW Transportation Carriers seek to deliver their load in the most efficient way possible, factoring in the need to maximize asset utilization and minimize cost. Carriers prefer to take the shortest path from origin to destination (referred to as the optimal route)

Inefficient Oversize/Overweight Transportation 67 6.2 Monetizing the Social Costs of Inefficient OSOW Routings It is challenging to assign dollar amounts to many of the societal costs noted above and even harder to allocate such costs accurately to truck transportation. Where possible, the research team has attempted to quantify the amount and the value of societal costs from OSOW shipping.

Figure 6-4 displays the total cost per mile of a legal 5-axle 80,000 lb truck and a permitted 5-axle 100,000 lb configuration on interstates, noninterstates on the National Highway System (NHS)

Inefficient Oversize/Overweight Transportation 69 6.3 Case Studies of Social Costs 6.3.1 Impact of Maximum Permitted Axle Weights on Route Selection OSOW carriers consider the regulatory burden and ease of travel when selecting a route and configuration. A carrier interviewed for this study was moving a load from Pennsylvania to Texas with a total loaded weight of 254,000 lbs.

Inefficient Oversize/Overweight Transportation 71 In addition to the carrier costs presented in Figure 6-6, a significant extra cost to the carrier and society was the time needed to reapply for and review permits in Ohio and apply for new permits in Indiana, Illinois, Missouri, Arkansas, and Texas after the initial route was denied by Tennessee. The permits used public sector resources above what would have been needed for the original route.

72 Multi-State, Multimodal, Oversize/Overweight Transportation is the potential for delay in the movement of the load due to utility involvement and the added cost of coordination with those utilities. Therefore the carrier chose to route through South Dakota and Minnesota to travel from Nebraska to Wisconsin.

Inefficient Oversize/Overweight Transportation 73 display the potential impact of an OSOW regulation on the carrier and the social cost of an OSOW load. 6.4 Social Costs of Inefficient OSOW Transportation An important takeaway from the comparison of optimal versus actual OSOW routes is that there are real public and private costs associated with OSOW regulations.
