In this work, we extend the time-dependent vehicle routing problem with time windows on a road network by considering two types of vehicles, large and small, to serve customers. Motivated from city logistics applications, large vehicles are forbidden from the downtown area. Accordingly, goods...

Evaluating the recognizability of street built environments provides crucial support for urban planning, security monitoring and navigation. Although street view images (SVIs) are widely used in urban studies, it overlooks the interconnection among different locations, which can also affect...

Which Americans experience the worst infrastructure? What are the costs of living with that infrastructure? We measure road roughness throughout America using vertical acceleration data from Uber rides across millions of American roads. Our measure correlates strongly and positively with other...

Extreme weather may give rise to the relocation of economic activity towards nearby locations. But how are the economic effects of weather events transmitted between locations? And, which role does the interconnection of small economic units play? This paper takes a granular approach to identify...

Road networks are one of the useful indicators through which sustainability of urban sprawl for an existing urban area and for a proposed new urban development area can be measured. Therefore, it is necessary for transportation engineers and urban planners to conduct various studies in this...

We study the efficiency of private supply of roads under demand uncertainty and evaluate various regulatory policies. Due to demand uncertainty, capacity is decided before demand is known, but tolls can be adjusted after demand is known. Policy implications can differ considerably from those...

There has been wide interest in private supply of roads as a solution to traffic congestion. We study its efficiency under demand uncertainty: we solve for equilibrium and optimum as benchmarks, and evaluate the efficiency of possible regulatory policies for private road operators. We obtain...

The paper was set to examine the relationship between different aspects of service trade and non oil export in Nigeria as well as assess the impact of capacity development on value of service trade and the implications for improving value of non oil export in Nigeria. Secondary data 1980 to 2010...

Road transport takes one of the leading positions in the organisation of freightage. Its domination causes road infrastructure congestion which affects its premature wear. That is why the condition of public roads takes an important part in road transport. The investments in road infrastructure...

Bhutan, in 2040, will be very different from what it is today. The transport system then needs to respond to the changing needs and demands. The Transport Integrated Strategic Vision 2040 incorporates all existing transport related plans, policies, initiatives, and actions to create a long-term...

Efficient procurement and utilization of woody biomass for bioenergy production requires a good understanding of biomass supply chains. In this paper, a dynamic optimization model has been developed and applied to estimate monthly supply and procurement costs of woody biomass required for the...

Assessing the trade impacts of domestic transport costs is data demanding and analyses that examine the effects of road quality, a critical aspect in regional and public policy, practically do not exist in the international trade literature. The few studies available rely mostly on...

Local road investments work for growth and poverty reduction in local areas. The paper highlights the importance of investing in local roads and directs attention to the critical role of local government units (LGUs) in improving the local road network. Raising additional monies to fund local...

Предложен подход к моделированию движения на сложных участках дорожно-транспортной сети, основанный на причинно-следственных комплексах. Подход позволяет...

Fiscal instruments are potentially among the most effective, and cost-effective, options for addressing externalities related to poor air quality, urban road congestion, and greenhouse gases. This paper takes a case study, focused on Mauritius (a pioneer in the use of green taxes) to illustrate...

Rwanda’s Economic Development and Poverty Reduction Strategy (EDPRS) covers the period 2008–12 and provides a medium-term framework for achieving the country’s long-term development aspirations as embodied in Rwanda Vision 2020, the seven-year Government of Rwanda (GoR)...

The problems of finding best facility locations require complete and accurate road networks with the corresponding population data in a specific area. However the data obtained from road network databases usually do not fit in this usage. In this paper the authors propose a procedure of...

В статье проведен анализ факторов, влияющих на состояние транспортной системы Армении и Азербайджана, показана особая роль политического контекста в развитии...
