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...

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...

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...

Managers of mobile photo enforcement (MPE) programs must account for several road safety goals when deploying operators. However, there is no MPE design structure to systematically connect deployment decisions back to preset goals. We propose a method to aid MPE managers in using goals directly...

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...

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...

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...

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....

Road geometry, vehicle characteristics, and weather conditions are all factors that impact a driver’s perception of a safe or credible speed and, consequently, the driver’s decision on whether or not to comply with the posted speed limit. In fact, the role a road’s environment plays in a driver’s...
