Traffic Engineering Service Christchurch
Moving vehicle is never free of traffic congestion especially in the cities. Every day commuters wastes hours in travelling just because of traffic engineering service christchurch. This has led to the emergence of vehicular management which will be beneficial for Road Transport department to control and manage the traffic flow on congested roads. Thus to support above idea we have Vehicular Ad-Hoc Network, or VANET technology that turns every participating car into a node, allowing cars to connect with each other and in turn create a network. It ensures there is proper co-ordination amongst the vehicles on the road and this in turn reduces Traffic Signs. This is also benefits the environment by reducing the pollution caused due to burning of fuel during traffic jams. In this paper cluster formation algorithm run on the vehicular environment so as to have a stable form of communication amongst the vehicles .
The transmission range of mobile terminals being is fixed, results in a dynamically changing network topology: As stations move around, some network links are destroyed while the possibility of new links being established arises. Thus, new routing protocols are needed for the dynamically changing ad-hoc wireless environment. The different cluster formation and routing protocols which suits the ad-hoc environment are to be simulated using NS2 and SUMO and results can be analyzed to have the best one. Thus for our simulation, real aspects of vehicular traffic is very essential and scenarios play a very crucial role.
•RSU (Road Side Unit) - It is the stationary unit that connects the roaming vehicles to the access network.
•OBU (On Board Unit) - It is network device fixed in roaming vehicle and is connected to the wireless network.
· Reduction of traffic engineering service christchurch: Messages which are exchanged among the moving vehicles help in distribution of information amongst them and thus reduces traffic load, driver spend less time on the roads.

The concept of leveraging wireless communications in vehicles has fascinated researchers since 1980’s . In the last few years we have witnessed a large increase in research and development in this area because traffic congestion has become a major concern. This technology treats every car as a moving node and thus these moving nodes form the network. In VANET communication is also made possible between these nodes via the transmission of messages in the wireless environment.
Also the vehicles have different destinations and hence over a course of time they follow different routes which lead to the change in the network, as result the vehicle network has no fixed topology and keeps on changing with time. From this it is clear that vehicle movement reflects the ad-hoc nature because of dynamic networks and hence the name VANET-
“Vehicular Ad-Hoc Network” is completely justified. There are two units which connect the vehicles with one another :

· Reduction in the number of accidents: Safety Product are given to the vehicles, information is available about the vehicles, and this is turn helps the drivers to avoid accidents.
