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...

Using police accident reports for Tippecanoe County, Indiana, and exploiting the introduction of the augmented reality game Pokémon GO as a natural experiment, we document a disproportionate increase in crashes and associated vehicular damage, injuries, and fatalities in the vicinity of...

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...

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...

Carpooling is now seen as last big opportunity to grow a shared mobility as a service (MaaS) business ahead of the arrival of autonomous vehicles (AVs). We present the case that Waze’s altruistic vision of carpooling is insufficient to scale the business. Our transactional vision of the...

Public transport provision requires substantial organisational efforts, careful planning, in some cases contributions from the public purse, and coordination between millions of passengers and staff members in large systems. Efficient resource allocation is critical in its daily operation, and...

Cost of entry is the most significant bugbear for potential operators wishing to enter the public transportation sector, which is a societal need given the duty of any society to provide for the transportation needs of its citizens as they move around, earning an income to provide for their...

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...

The COVID-19 pandemic that began in the last quarter of 2019 seriously impacted the transportation industry. Countries around the world adopted various restrictions and policies to prevent the spread of the pandemic, which resulted in a sharp drop in the demand for transportation of goods. In...

Place-based accessibility measures, such as the gravity-based model, are widely applied to study the spatial accessibility of workers to job opportunities in cities. However, gravity-based measures often suffer from three main limitations: (1) they are sensitive to the spatial configuration and...
