Traffic Congestion, Reliability and Logistical Performance: a Multi-sectoral Assessment
نویسندگان
چکیده
Recent research has updated a 1998 study of the effects of traffic congestion on logistical efficiency in the UK. It has focused on the contribution of congestion to unreliability across nine sectors. The relationship between traffic flow and transit time variability has been modeled using data from the Highways Agency and speed-flow ratios. An analysis of transport KPI survey data and an interview survey of 32 managers in 24 companies have explored the relative importance of congestion, The survey also examined the extent to which companies are adapting their logistical systems to worsening traffic congestion in the UK.

Design of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems
Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...
متن کاملGis-based Multi-agent Traffic Micro Simulation for Modelling the Local Air Pollution
Air pollution from motor vehicles is one of the most serious and rapidly growing problems in metropolitan areas. It is occurred especially in major arterial streets inside the metropolitan central district because of the heavy traffic congestion suffering. Although transportation networks operate as an integrated system, at a regional level we can safely assume that local urban congestion will ...
متن کاملPerformance Improvement of Expanded Integrated Local Area Networks (RESEARCH NOTE)
In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
متن کاملCongestion Free On-Chip Network Design Using An Agent-Based Management Method
Congestion in on-chip networks may cause many drawbacks in multiprocessor systems including throughput reduction, increase in latency, and additional power consumption. Furthermore, conventional congestion control methods, employed for on-chip networks, cannot efficiently collect congestion information and distribute them over the on-chip network. In this paper, we present an on-chip network ar...
متن کاملLiterature Review of Traffic Assignment: Static and Dynamic
Rapid urban growth is resulting into increase in travel demand and private vehicle ownership in urban areas. In the present scenario the existing infrastructure has failed to match the demand that leads to traffic congestion, vehicular pollution and accidents. With traffic congestion augmentation on the road, delay of commuters has increased and reliability of road network has decreased. Four s...
