Airport leakage is a phenomenon that occurs when air passengers choose to travel longer surface distances to take advantage of better air services at an out-of-region airport (which we term the “substitute” airport), instead of using their local airport as would be expected (Suzuki & Audino,...

This study examined the safety effects of the City of Edmonton’s mobile enforcement program. Four years of city-wide monthly collision data, enforcement statistics, and employment rate data was incorporated in a generalized linear Poisson model. It was found that the estimations of the...

Airspace Flow Programs (AFPs) assign ground delays to flights in order to limit flow through capacity constrained airspace regions. AFPs have been successful in controlling traffic with reasonable delays, but a new program called the Combined Trajectory Options Program, or CTOP, is being explored...

Before-and-after empirical Bayes evaluation of automated mobile speed enforcement on urban arterial roads
Download2019-11-12
Li, R., El-Basyouny, K., Kim, A.
Speeding is a leading factor in road collisions and is found to contribute to approximately one third of fatal collisions. Speed enforcement is one of the most common countermeasures used to reduce speed. However, a gap exists in the literature regarding the effectiveness of automated mobile...

This paper introduces an empirically driven, nonparametric method to isolate and estimate the effects of demand and throughput changes to observed changes in flight delay. Classical queuing model concepts were used to develop a method by which an intermediate queuing scenario could be...

Deconstructing delay: A non-parametric approach to analyzing delay changes in single server queuing systems
Download2019-11-12
This paper introduces an empirically driven, non-parametric method to isolate and estimate the effects that changes in demand and changes in throughput have on delay – in particular, arrival and departure flight delay at airport runways. Classical queuing model concepts were used to develop a...

Development and evaluation of adaptive transit signal priority control with updated transit delay model

Han, X., Li, P., Sikder, R., Qiu, Z., Kim, A.
Transit signal priority (TSP) strategies are widely used to reduce bus travel delay and to increase bus service reliability. State-of-the-art strategies enable dynamic (and optimal), rather than predetermined, TSP plans to reflect real-time traffic conditions. These dynamic plans are called...

Factors Affecting Classification of Road Segments into High-and Low-Speed Collision Regimes
Download2019-11-12
Gargoum, S., Li, Y., El-Basyouny, K., Kim, A.
The safety of locations operating under high-speed conditions could significantly differ from that of locations operating under low-speed conditions. Therefore, different approaches must be adopted when analyzing and managing speed and safety at locations operating under different regimes....

Woo, M., Hui, K. T. Y., Ren, K., Gan, K. E., Kim, A.
The May 2016 wildfire of Northern Alberta – the costliest wildfire disaster in Canadian history to date – led to an area-wide evacuation by road and air. Traffic count and flight data were used to assess the characteristics of the evacuation, including estimating people movements by vehicle and...

Kim, A., Rokib, S. A., Liu, Y.
This paper presents a method for obtaining airfield capacity estimates, using historical data from the Federal Aviation Administration’s Aviation Systems Performance Metrics (ASPM) database. The process first involves merging individual flights and quarter-hour airport runway operations datasets...
