The objectives of this logistics augmentation to the Freight-Truck-Pavement interaction pilot study are: (1) to provide a basic understanding to Caltrans of private-sector decision making in road-freight transportation; (2) to identify and describe the comprehensive set of interactions between the efficiency and efficacy of road-freight transportation and the capacity, performance and regulation of road infrastructure in the state and recommend which of these interactions warrant more in-depth assessment on a statewide scale to quantify the overall economic and efficiency impact road infrastructure decisions have on the economy of California; and (3) to illustrate the value of direct interactions and consultations with private companies in exploring private sector decision making and the interdependence of these decisions on public sector actions. Conclusions: By using desktop studies, qualitative analysis, and case studies, this study has shown that road infrastructure and regulation, as managed by Caltrans, have a marked impact on supply chain operations and strategies. Given the critical role that supply chains play in the economic well-being of and quality of life in California and the dependence of these supply chains on road infrastructure and regulation, it is imperative that the public sector (Caltrans) and the private sector engage in the planning and construction of road infrastructure as well in the drafting and implementation of policy.This pilot study has shown that road infrastructure and regulations have a direct effect on supply chain vulnerability, and that design and private companies need to consider these elements in their decision making. Recommendations: Recognize that supply chain vulnerability and design are different for each economic goods movement-dependent sector and therefore a blanket approach to the treatment of sectors will not suffice, and In order for this study to be comprehensive enough to form part of Caltrans’ routine decision making regarding road infrastructure and regulation, expand the study’s scope to cover all goods movement-dependent sectors and deepen the study by conducting representative case studies of each sector.
