Finding Computationally Inexpensive Methods Model Flow Past Heavy Vehicles Active Flow Control Systems Drag Reduction
2015/7/6
This paper explores the use of computational tools to analyze the aerodynamic e ects that Coanda jets have on the drag, stability and maneuverability of heavy vehicles. To facilitate the analysis and ...
Modelling heterogeneous traffic flow on upgrades of intercity roads
upgrade power-to-weight ratio acceleration rates heterogeneous traffic simulation speed–volume relationships speed–distance profiles
2010/10/29
The effect of an upgrade and its length is very significant for traffic flow characteristics. Road traffic in developing countries like India is highly heterogeneous comprising vehicles of wide rangin...
Saturation flow versus green time at two-stage signal controlled intersections
saturation flow traffic signals green time intersection capacity
2010/10/29
Intersections are the key components of road networks considerably affecting capacity. As flow levels and experience have increased over the years, methods and means have been developed to cope with g...
Mathematical modelling of network traffic flow
traffic flow intersection modelling traffic flow regulation vehicle
2010/11/1
The article describes mathematical models of traffic flows to initiate different traffic flow processes. Separate elements of traffic flow models are made in a way to be connected together to get a si...
Pessimistic Equilibrium Flow and Its Network Design Implications
Pessimistic Equilibrium Flow Network Design
2009/9/29
Quality of service in urban transportation network is very important to the users of this network. Travel time in street networks is one, very important, aspect of this service, particularly for trips...
第八届国际交通流与颗粒流学术会议（TGF’ 09）将于2009年6月21日～24日在上海大学举行。自1995年以来，这个系列国际会议已经成功举办了七届，成了反映交通流和颗粒流研究进展的一个活跃的国际交流平台。国内学者曾参加了多届会议，在国内外学界产生了较大的影响。2007年6月上海大学戴世强教授带领十位研究人员参加了在巴黎举办的第七届会议（TGF’07），交流了十一项研究成果，并在会议期间经过...
Interdependence of noise and traffic flow
traffic flow noise statistics regression distribution
2010/11/1
Traffic flows in cities, especially in city centres, are intensive and uneven, moreover, registered noise levels exceed allowable limits. Noise levels have been measured at K. Mindaugo ave. and Bir...
Determination of traffic flow parameters in different traffic flow interaction cases
traffic flow kinetic theory modelling characteristic method
2010/11/1
Modelling of straight road section consisting of one traffic line gives the opportunity to simulate “follow the car” system. In general it looks like a line of vehicles, going one after another. Kinet...
