Extreme value theory: Applications to estimation of stochastic traffic capacity and statistical downscaling of precipitation extremes
… value analysis. First, we apply EV techniques to traffic stream data to develop an accurate distribution of capacity. Data were collected by the NHDOT along Interstate I93, and two adjacent locations in Salem, NH were examined. Daily flow maxima were used to estimate capacity, and data not …

From marginalized to optimized : re-envisioning urban highway corridors
… has assumed relentless growth of vehicular traffic capacity. Yet today is an era of highway rationalization, aging facilities, strained finances, peak oil concerns, climate change, and urban regeneration. It is a prudent time to re-examine the place of highways within the urban fabric. The …

Green optical network design : power optimization of wide area and metropolitan area networks
… in technology are fueling huge growth in network traffic capacity. Demand for low cost, reliable, and high bitrate transmissions grows 40-110% internationally every year. To date, most research has focused on cost minimization of wide area and metropolitan area networks. In this thesis, we …

Propagation channel models for 5G mobile networks. Simulation and measurements of 5G propagation channel models for indoor and outdoor environments covering both LOS and NLOS Scenarios
… for broadband mobile services; however, mobile traffic is still growing at an unprecedented rate and the need for more sophisticated broadband services is pushing the limits on current standards to provide even tighter integration between wireless technologies and higher speeds. This has led to …

Optimisation of Rail-road Level Crossing Closing Time in a Heterogenous Railway Traffic: Towards Safety Improvement - South African Case Study
… of the level crossings where railway and road traffic intersects. Thus, long waiting time is expected at the level crossings due to the increase in traffic volume and heterogeneity. Furthermore, safety and capacity can be severely compromised by long level crossing closing time. The emphasis of …

High Capacity VCSEL Array Based Optical Wireless Links
… increases the future demand for mobile data traffic capacity. However, the limited RF spectrum is not sufficient to meet this demand. Optical wireless communication (OWC) systems have the potential to overcome the rapidly increasing demand for indoor data traffic. Compared to Radio frequency …

Concession analysis for highway infrastructure projects financed as public-private partnerships
… an Agent-Based Modeling (ABM) framework for traffic simulation is created to provide traffic estimates that account for road user behavior in mitigating the traffic demand risk from a lifecycle perspective. The application of the ABM framework facilitates the transportation project evaluation …

String Stable Constant-Spacing Platoon with Robustness to Communication Delays and Cutoff
… delays and cutoffs, which are common in modern traffic networks. Therefore, this thesis develops a new constant-spacing control approach that is robust to communication delays and cutoff. Moreover, this thesis develops conditions for guaranteeing string stability for constant-spacing policy …

Development of Aircraft Wake Vortex Dynamic Separations Using Computer Simulation and Modeling
… separations, which could result in a runway capacity increase. Aircraft separation is a major obstacle to increasing the operational efficiency of the final approach segment and the runway. An aircraft in motion creates an invisible movement of air called wake turbulence, which has been shown …

A Computer Model to Predict Potential Wake Turbulence Encounters in the National Airspace
… problem has become more important for airport capacity and the en-route air traffic operations. The vortices generated by heavy and super heavy aircraft can generate potential hazards to other aircraft on nearby flight paths. Moreover, the design of new airport procedures needs to consider the …
