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 reviews and critiques the growth management system in Montgomery County, Maryland with the intent of finding generalizable lessons. An overview of the twenty year old system is followed by an analysis of its consequences and implications. The system fails to provide effective price...

Where large-scale investments are needed, especially for infrastructure projects, public-private partnerships (PPPs) have been touted as an option. With encouragement by the international financial institutions, PPPs have been promoted in developing countries, especially those facing large...

The present research develops an agent-based model to treat the organization, growth, and contraction of network elements. The components model travel demand, revenue, cost, and investment. Revenue earned by links in excess of maintenance costs is invested on the link to until all revenue is...

It has become increasingly common to allocate highway franchises to the bidder that offers to charge the lowest toll. Often, building a highway increases the value of land held by a small group of developers, an effect that is more pronounced with lower tolls. We study the welfare implications...
