We give an explicit upper bound for the number of isolated intersections between an integral curve of a polynomial vector field in Rn and an affine hyperplane. The problem turns out to be closely related to finding an explicit upper bound for the length of ascending chains of polynomial ideals spanned by consecutive derivatives. This exposition constitutes an extended abstract of a forthcoming ...

This investigation examined short-term changes in child and adult cyclists' gap decisions and movement timing in response to general and specific road-crossing experiences. Children (10- and 12-year-olds) and adults rode a bicycle through a virtual environment with 12 intersections. Participants faced continuous cross traffic and waited for gaps they judged were adequate for crossing. In the co...

New ideas are explored for managing multimodal traffic on isolated approaches to signalized intersections. Strategies are proposed that both: segregate distinct modes along the approach, and more effectively resolve the disruptive capacity-reducing conflicts that arise between throughmoving and turning traffic traveling in adjacent lanes. The proposed schemes produce capacities that consistentl...

Contextual factors such as ethnicity, gender, place, and their intersections determine the social condition that populations and individuals live in. As a result, environmental stressors that shape exposures, and also resilience and vulnerabilities are specific to the population. This emphasizes the role of the intersection of such contextual factors in studying psychosocial causes of depressio...

Many studies have used Global Navigation Satellite System (GNSS) traces to successfully extract segments of road networks because such data can be rapidly updated at a low cost. However, most studies have not focused on extracting intersections, which are indispensable parts of road networks in terms of connectivity. However, extracted intersections often present unsatisfactory precision and mi...

Establishing verbal memory traces for non-verbal stimuli was reported to facilitate or inhibit memory for the non-verbal stimuli. We show that these effects are also observed in a domain not indicated before-wayfinding. Fifty-three participants followed a guided route in a virtual environment. They were asked to remember half of the intersections by relying on the visual impression only. At the...

Traffic congestion has long been a worldwide difficult problem in metropolitan transportation networks, incurring tremendous time waste and exhaust pollution. Extensive efforts have made to address this problem, among which traffic control at intersections is known be especially crucial while challenging. Also, it helpful the recent advent of autopilot technologies by enhancing schedule accurac...

Signalized intersections dominate traffic flow in urban areas, resulting increased energy consumption and travel delay for the vehicles involved. To mitigate negative effect of lights on eco-driving control electric vehicles, a multi-intersections-based eco-approach departure strategy (M-EAD) is proposed to improve vehicle efficiency, throughput, battery life, while maintaining acceptable drivi...

Real-time incident-responsive traffic control and management is vital to development of advanced incident management systems in ITS. More importantly, it provides, from an academic point of view, the linkages between incident detection, incident management, and traffic signal control. This study explores the application of a stochastic optimal control approach to real-time incident-responsive t...
