Megaregion planning presents an alternative way of mitigating metropolitan problems of large-scale transportation systems, green infrastructure, and economic development and has attracted a number of transportation advocates since 2000.

The work was conducted in two phases over a 4-year period beginning in 2007 and this report details the second phase conducted over the period 2009-2011. It reports results in three areas: 1) total operating costs for the major vehicle classes currently seen on Texas highways, 2) engine models for hybrid light vehicles, and 3) results from examining the impact of transmission types through gearbox and differential sub-models. This second phase is the focus of this report but the reader interested in why this work was undertaken should peruse technical report 0-5974-1. This second, and final, report contains several detailed appendices on mechanical engineering sub-models and a product-a Vcost model and manual-for TxDOT use in highway and freight planning, economics and departmental revenue estimation. (Note: Traditionally vehicle operating costs were termed VOCs but the current use of this acronym to represent volatile organic compounds in emission studies encouraged the authors to adopt a different term-Vcost.

Economists have also predicted that oil prices will rise in real terms during the same period. Air quality is getting worse in a number of metropolitan areas, triggering non-attainment penalties and spurring an interest in cleaner transportation. Incentives and new policies must be adopted to increase the efficiency of the transportation system and thus move freight with a reduced impact on society and the environment. Hybrids can potentially help solve this issue through their increased fuel economy and reduced emissions. This project evaluated a package delivery truck, beverage delivery truck, and a refuse truck. The research determined that the additional cost (with current prices) of the hybrid refuse truck was justified, but not for the other two trucks. The social cost of emissions was also estimated to help justify hybrids' implementation. With this information, the rate of hybrid truck adoption was estimated for various policy scenarios. The results indicated that a correctly designed incentive program can greatly increase the rate of hybrid adoption and could be justified by the additional social benefits of emissions reduction.
