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...

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....

Development and evaluation of adaptive transit signal priority control with updated transit delay model
Download2019-11-12
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...

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...

Reconstructing an Emergency Evacuation by Ground and Air the wildfire in Fort McMurray, alberta, Canada
Download2019-11-12
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...

Relationship between road safety and mobile photo enforcement performance indicators: A case study of the city of Edmonton
Download2019-11-12
Li, R., El-Basyouny, K., Kim, A., Gargoum, S.
Mobile photo enforcement (MPE) programs are commonly implemented to regulate speed and improve road safety. However, most previous research focuses mainly on validating the safety effects of MPE, with very minimal discussion on the enforcement performance indicators (EPIs). Therefore, the goal of...

Some insights into a sequential resource allocation mechanism for en route air traffic management
Download2019-11-12
This paper presents a game theoretic model of a sequential capacity allocation process in a congestible transportation system. In this particular application, we investigate the governing principles at work in how airlines will time their requests for en route resources under capacity shortfalls...

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...

Many runway capacity estimation models are available today, and developers usually claim that their models have been validated. However, information about the validation process is often limited, and different models are validated at differing levels of complexity. This paper proposes two...

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...
