Do travel options influence how commute time satisfaction relates to the residential built environment? Universiteit Gent Universiteit Antwerpen
Although previous studies have explored how satisfied people are with their travel, the link with the built environment and available travel options is unclear. This research investigates whether travel options influence how commute time satisfaction relates to the built environment. First, profiles among commuters in terms of commute time satisfaction (CTS) and residential built environment (RBE) were identified by performing a cluster analysis ...
What comes first : crime or police? A spatiotemporal perspective on reported crimes and tracked police presence Universiteit Gent
The majority of motor patrol officers spent their shifts being out in the field. Patrol officers are either assigned and responding to emergency calls from citizens or being unassigned and patrolling police beats at their own discretion. What remains unclear is the existence or the extent of crime preventive effects of police presence across microgeographic units. To this end, more than 84,000 reported crimes and 290 million individual GPS ...
Evolution of air transport networks under different airline business models : the case of three Chinese airlines Universiteit Gent
This study was conducted to compare the evolution process of air transport networks (ATNs) under different airline business models, and empirically analyzed the causes of evolution differences combining with airline market behaviors. Three representative Chinese airlines (China Southern Airlines, Spring Airlines, and Lucky Air) that belong to three business models (full-service, low-cost, and regional) were examined. Based on mathematical ...
Simulation analysis on flight delay propagation under different network configurations Universiteit Gent Universiteit Antwerpen
This paper investigates flight delay propagation in air transportation networks (ATNs) by considering both network structures and airport operation performance. An airport susceptible-infected-recovered (ASIR) model is established based on the mechanism of epidemic spreading, where the focus is on the impact of the infection rate in order to properly map and understand the probability of delay propagation. Different network configurations are ...

Modeling the evolutionary mechanism of China's domestic air transport network Universiteit Gent Universiteit Antwerpen
With the rapid expansion of China's domestic air transport network (CATN), it is fundamental to model which factors and mechanisms impact this development. This paper investigates how the combined endogenous and exogenous factors influencing the evolution of CATN based on longitudinal data by utilizing a more all-encompassing methodology of stochastic actor based-modeling (SABM). Endogenous variables include a density effect, a betweenness ...
Congestion spillover effects of Chinese hub airports on international connecting traffic Universiteit Gent Universiteit Antwerpen
Factors shaping non-stop airline services in the transatlantic air transport market : 2015-2017 Universiteit Gent Universiteit Antwerpen
This paper investigates the impact of alliance, cannibalization and network structure on carriers' nonstop entry into transatlantic markets with previously coexisting nonstop and one-stop service. The results show that market concentration measured by international airline alliances and joint ventures has a positive impact on carriers' entry, with the latter presenting a more accurate representation of market concentration in the transatlantic ...
