Measuring the interaction between cities is an important research topic in many disciplines, such as sociology, geography, economics, and transportation science. The traditional most widely used spatial model gravity model, but it requires parameters to be artificially set. In this paper, we propose a parameter-free interactive city choice (ICC) that measures intercity from perspective of indiv...

This paper explores the relationship between forced migration and the city. The paper outlines four accounts of the city centred on: displacement and the camp-city, dispersal and refugee resettlement, the ‘re-scaling’ of borders, and the city as a sanctuary. Whilst valuable, these discussions maintain a focus on sovereign authority that tends to prioritize the policing of forced migration over ...

The seminal Buchanan-Ng club model is used to analyze optimal allocation of population between non-homogenous cities. Because of externalities (marginal welfare effects), migration cannot alone ensure efficiency and policy intervention is needed. In principle, a first-best optimum is achievable, if the externalities are properly calculated and internalized to people’s decisions by local or cent...

This study aims at identifying the differences of crash characteristics at basic segments between urban and intercity expressways. Crash rate (CR) model is firstly developed as a function of traffic density. The causes leading to different CR characteristics by expressway type are then examined considering the interaction of geometry, traffic flow and ambient conditions. Affecting mechanisms of...

The global city thesis and the migration thesis concern two important dimensions of the impacts of contemporary globalization on cities. The two theses are intrinsically linked. The central question is how we should approach migration in the new context of the global city, and how we should articulate their interrelationships. To address this question, we construct an integrative analytical fra...

Using data collected from one of the most popular city-to-city ridesharing platforms, we study how individual drivers respond to an increased health hazard. We analyze impact Covid-19 outbreak on level mobility and price ridesharing. show a higher prices larger dispersion in areas with risk. exploit daily discontinuities reporting cases argue that variation is due drivers’ perception risks. Our...

Whole body vibration exposure of the train drivers working for State Railway Lines is assessed by referring to ISO standard 2631 -1 and EU directive 2002/44/EC. The vibration measurements were done in the cabins of suburban and intercity train drivers. Suburban train driver performs his job usually in standing posture. Whereas intercity train driver works generally in seated (bending forward) p...
