Circuity, the ratio of network distances to straight-line distances, is an important measure of urban street network structure and transportation efficiency. Circuity results from a circulation network’s configuration, planning, and underlying terrain. In turn, it impacts how humans use urban...

Complex systems have been widely studied by social and natural scientists in terms of their dynamics and their structure. Scholars of cities and urban planning have incorporated complexity theories from qualitative and quantitative perspectives. From a structural standpoint, the urban form may...

The pandemic due to the coronavirus disease 2019 (COVID-19) by its nature has affected all aspects of life. The impact on transportation sector has been investigated immediately as it played an important role in sustaining crucial functions. There are yet many unknowns regarding the future. This...

We are entering a period of dynamic and fundamental change in the transportation and logistics industry. The communication and collaborative aspects of the Internet are changing the way firms develop their logistics strategies, processes and systems. Internet and digital technologies help...

This report estimates the CO2 emissions of freight transport on a hypothetical high-speed rail (HSR) line along the northern route, from Lyon to Warsaw, of a 'European Silk Road' (ESR). Using a methodology consisting of predictions regarding the freight-carrying capacity of the future HSR, and...

With the impacts of climate change intensifying, sea level is expected to rise 0.25–0.30 meters by 2050. With a one-degree Celsius rise in temperature, precipitation globally is expected to increase by 7%. An important service linked to these pressures are roads, which are known to flood and...

Despite rapidly emerging innovative road pricing and investment principles, the development of a long run network dynamics model for necessary policy evaluation is still lagging. This research endeavors to fill this gap and models the impacts of road financing policies throughout the network...

Transportation analysts and the public decision-makers they support are confronted with a broad range of analytical tools for estimating the economic impacts of improvements to transportation networks. Many of the available models operate at different scales and have distinctly different...

The implementation of biodiesel in Indonesia has been regarded as one of the main strategies to improve country's energy security equally and equitably. However, as the largest archipelago country in the world, the activity in distributing their biodiesel production bears a key problem. The...
