This research investigates the self-organization of surface transportation networks. Using a travel demand model coupled with revenue, cost, and investment models, experiments are run under a variety of parameters on a grid network. It is found that roads, contiguous sections of multiple links...

This paper analyzes governance choice in a two-level federation in providing road infrastructure across jurisdictions. Two models are proposed to predict the choice of centralized or decentralized spending structure on a serial road network shared by two districts. While the first model...

This study estimates the operating costs for commercial vehicle operators in Minnesota. A survey of firms that undertake commercial truck road movements was performed. The average operating cost per kilometer for commercial vehicle operators was calculated from the survey responses. Results show...

Spring Load Restrictions (SLR) impose load restrictions on heavy trucks during the spring thaw period. Although the policies have been implemented for many years, we are still unsure of their economic effects on truckers. This paper overviews practices around the world and sets up a framework to...

The spring load restriction policy of Minnesota has been in effect for over 50 years with little consideration given to the cost that it imposes on the freight industry. A cost-benefit study was recently commissioned to examine the policy. The cost-benefit analysis required a precise estimate of...

Computer simulation plays an increasingly important role in engineering education as a tool for enhancing classroom learning. This research investigates the efficacy of using simulation in teaching the topic of transportation network growth through an experiment conducted at the Civil...

This paper investigates the relationship between the growth of road networks and regional development. We test for mutual causality between the growth of road networks (which are divided functionally into local roads and highways) and changes in county-level population and employment. We employ...

The paper analyzes the political acceptability of policies targeted at relieving urban congestion. The paper combines a stylized model of an urban transport network with a somewhat more detailed model of the political process that incorporates interactions between voters, special interest groups...

This work examines the temporal-spatial variations of daily automobile distance traveled and greenhouse gas emissions (GHGs) and their association with built environment attributes and household socio-demographics. A GHGs household inventory is determined using link-level average speeds for a...

En Centroamérica las distancias son cortas y los volúmenes de carga son pequeños para consolidar una red densa de transporte marítimo de corta distancia. Además, no existe una red ferroviaria transnacional. Esto otorga al transporte automotor de carga (TAC) un rol clave en el transporte...
