Data-driven modeling of the airport runway configuration selection process using maximum likelihood discrete-choice models
… such as wind speed, wind direction, visibility, traffic demand, air traffic controller workload, and the coordination of flows with neighboring airports influence the selection of the runway configuration. This paper identifies a discrete-choice model of the configuration selection process from …

Intelligent Lane Utilisation to Improve Freight Transportation Mobility on Arterials
… activities in urban areas have increased truck traffic on urban roadways, which raises safety and operational concerns. The governing agencies are planning to improve the efficiency by adopting the Intelligent Lane Utilisation (ILU) tactics along the highways and major arterials. Truck only lane …

Dual Wi-Fi: Dual Channel Wi-Fi for Congested WLANs with Asymmetric Traffic Loads
… the AP to the clients (Downlink), far outweighs traffic demand from the clients to the AP (Uplink), thereby yielding traffic asymmetry. Moreover, when many clients associate with a single AP, the clients can cause a disproportional amount of medium contention compared to the AP, producing …

Operational upgrades to improve traffic flow in Small Middleweight Cities: Windhoek, Namibia
… to ascertain its influence on a growing urban traffic demand. This dissertation assesses the influence that the conversion of Werner List Street into a one-way street has on the performance of traffic accommodation. Werner List Street links traffic commuting from the south to the north of …

Comparison of Microscopic and Mesoscopic Traffic Modeling Tools for Evacuation Analysis
… and to compare the INTEGRATION microscopic traffic simulation model against the MATSim mesoscopic model. Given that the demand was the same for both models, the comparison was achieved based on three indicators: estimated evacuation time, average trip duration, and average trip distance. The …

Quantification of the effect of air traffic on terminal precinct ground traffic and the corresponding ground traffic effect on kerbside and parking infrastructure requirements at O.R. Tambo international airport
The sharp increase in travel demand at ORTIA In recent years has been translated into frequent parking supply and kerbside pickup/drop-off bay shortages, particularly during peak periods. This often results in long delays and Increased frustration amongst those using these facilities. In an attempt …

An adaptive strategy for providing dynamic route guidance under non-recurrent traffic congestion
Traffic congestion on urban road networks has been recognized as one of the most serious problems with which modern cities are confronted. It is generally anticipated that Dynamic Route Guidance Systems (DRGS) will play an important role in reducing urban traffic congestion and improving traffic …

Real-Time Estimation of Traffic Stream Density using Connected Vehicle Data
The macroscopic measure of traffic stream density is crucial in advanced traffic management systems. However, measuring the traffic stream density in the field is difficult since it is a spatial measurement. In this dissertation, several estimation approaches are developed to estimate the traffic …

Evaluation of bus priority strategies for BRT operations
… different conditions such as headway, loads, and traffic demand in a BRT context. Results for both case studies support the belief that TSP can provide travel time reductions for transit vehicles, together with reductions in headway variability. However, results proved to be very sensitive to …

Optimal traffic control for a freeway corridor under incident conditions
… caused by incidents, is the main cause of traffic delays and causes up to 60 percent of the freeway delay in the United States. When severe incidents occur on freeways, capacity reduction due to lane blockages may cause an extremely high amount of traffic delay. In many cases, parallel …

Control of wireless networks under uncertain state information
… is determined by the network's stochastic traffic demand. Solving this joint learning and scheduling problem is complex. In this thesis, we devise queue-length-based scheduling policies that can adapt to the network's traffic, while simultaneously exploring the channel conditions. We begin …
