Traffic congestion estimation in vehicular ad hoc networks can have many interesting applications. In this paper, we propose two measures of traffic congestion around a vehicle suited for different applications. A scheme for a vehicle to estimate congestion around it is proposed and evaluated through simulations. We also show an application of the estimated congestion for information disseminat...

The road network is salvation for economy of any region and social welfare. In observation of dynamicity on road networks and the sharp increase of traffic congestion, accidents, states, the road traffic management becomes more challenging research area. It is need to develop efficient and optimized road network management to prevent the traffic congestion and accidents in the present developme...

ITE JOURNAL / APRIL 2001 TRANSPORTATION PLANNERS often compare traffic to a fluid, assuming that a certain volume of vehicles must flow through the road system like water through a network of pipes. But in many situations urban traffic is more comparable to a gas, which expands to fill available space. Road improvements that reduce users’ travel costs tend to attract traffic from other routes, ...

Navigators based on real-time traffic conditions achieve suboptimal results since, in face of congestion, they greedily shift drivers to currently light-traffic roads and cause new traffic jams. This article presents Themis, a participatory system navigating drivers in a balanced way. By analyzing time-stamped position reports and route decisions collected from the Themis mobile app, the Themis...

Congestion plays a vital role in degrading the performance of the network. Under idle condition, network traffic is less whereas when an event is detected, the network traffic becomes high thus leading to congestion in the network. To ensure the reliability of the network an efficient protocol is proposed to detect and control congestion. Though there are various sources for congestion, the sig...

Accidents and congestion are two frustrating events, which can be observed very frequently on roads. Accidents, especially on expressways, can trigger heavy traffic congestions imposing huge external costs and reducing the level of service. Therefore it is obvious that accidents clearly have an impact on congestion. But the opposite, i.e. the effect of congestion on occurrence of accidents, is ...

The proposed system exhibit the issues of congestion in WSN which usually takes place when the quantity of the sensor motes reporting data maximizes towards sink mote. This phenomenon will cause minimization of optimal throughput and loss of valuable data. The proposed system highlights a novel approach for mitigating the ill-effects of traffic congestion in the area of wireless sensor network....

This paper discusses the evolution of the congestion controls that govern all Internet traffic. In particular we chronicle and discuss the implications of the fact that the most significant "congestion signals" are increasingly coming from network operators, not the TCP stack. Providers now nudge users into different traffic patterns using a variety of new technical and non-technical means. The...

Due to the unpredictable behavior of the traffic and various traffic characteristics, it has become a great challenge for ATM networks to effectively control traffic and congestion while at the same time provide the desired quality of service. In this paper, a fuzzy logic traffic controller is proposed to perform traffic and congestion control functions. Simulation results showed the feasibilit...
