Possible gender differences in the workplace are always a hot topic because they might explain why men continue to dominate in the jobs arena, despite the significant headway being made by women. Recent data indicate that males and females have somewhat differing priorities in their jobs but share basic ideas of what they think is important. Some research has shown that a supposed values gap be...

Density fluctuations in traffic current are studied by computer simulations using the deterministic coupled map lattice model on a closed single-lane circuit. By calculating a power spectral density of temporal density fluctuations at a local section, we find a power-law behavior, ∼ 1/f, on the frequency f , in non-congested flow phase. The distribution of the headway distance h also shows the ...

Car following (CF) models used in traffic engineering are often criticized for not incorporating "human factors" well known to affect driving. Some recent work has addressed this by augmenting the CF models with the Task-Capability Interface (TCI) model, by dynamically changing driving parameters as function of driver capability. We examined assumptions of these models experimentally using a se...

A dynamic feedback system is developed for estimating the headway and velocity in a longitudinal three-vehicle platoon. The estimation system is modeled using a particle filter (PF) and an unscented Kalman filter (UKF) that estimate them by measuring the acceleration rate and/or velocity of probe vehicle(s) in the platoon. State equations are defined as a discrete conservation equation of headw...

A new cellular automaton traffic model is presented. The focus is on mechanical restrictions of vehicles realized by limited acceleration and deceleration capabilities. These features are incorporated into the model in order to construct the condition of collision-free movement. The strict collision-free criterion imposed by the mechanical restrictions is softened in certain traffic situations,...

Scholarship and implementation in information and communication technologies for development (ICTD/ICT4D) have seen an exponential increase over the past decade. In spite of enormous headway in both research and application, ICTD lacks a clear unified framework that can guide contextually grounded user-focussed design of ICT. This shortcoming results largely from the field’s unusual placement a...
