Moreover, it has drawn increasing attention for its low cost, safety, and a performance close to an active suspension[1~3].
The a will be smaller with the velocity increasing of car, increase vehicle safety in high speed.
Based on national standards and traffic regulations, the inter-state highway speed limit falls mostly in the 60-80 km/h range, and the highway speed limit is 120 km/h.

Three-phase classification of an uninterrupted traffic flow: a k-means clustering study.

Thus, by reducing or eliminating redundant data in order to optimize network traffic, Shown in Fig.4, we can say that with the help of data aggregation process we decrease the number of data, as well as reducing the MAC layer multiple access control to achieve energy savings [7].
transmitted to the relay node i,In this case the waiting time of the packet WTi calculated as Eq. 1 WTi=Tdeadline-Hops*EHD2-1Hops*α (1) Hops=di,sinkdi,next (2) Where,Tdeadline is used to indicate how much time it remains for the packet before its deadline and has an important role in making routing decisions;EHD The value of single-hop time delay estimation (including channel competition, transmission time, and the queuing time);di,sink and di,next is Euclidean distance.Given two nodes geographic locationx1,y1,x2,y2,Euclidean distance calculation formula asEq. 3 x2-x12+y2-y12 (3) The parameter α is a constant factor used to leave some remaining time as a safety
In this article, we set the parametersα=0.7, Means that packet to the target delay is set to 0.7 times the available idle time, leaving the remaining time as a safety margin.At relay aggregation node i, polymerization adopt FIFO queue model[10]，Set aggregation queue size is D, That i nodes can aggregate maximum number of packets，Then aggregation into a packet is forwarded to the next node.

Introduction In 1970s, the American suburbs, which experienced sensible growth during previous decades, started to face a decline due to worsening traffic congestions which encouraged people enjoying a less stressful commute to work [1].
Hence, higher income people will likely exert pressure to maintain safety and order in the neighborhood, enforcing rules to protect their investments [24] and threatening this physical coexistence.

In 1975, the first “the restoration of damaged ecosystems” international conference held in the United States, on which ecological restoration principles, concepts and characteristics are discussed.
Over the next 20 years, there held a number of related international symposium.
In the Sixth International Congress of Ecology, held in the UK in 1994, ecological restoration study is one of the 15 topics[12].
If it is found that, people immediately move avoidance, or to reduce the damage of buildings for the purpose of protection measures to ensure the safety of people's property and housing.

According to the IMO safety Committee (NAV) in July 1998, on the recommendations of the Conference, from July 1, 2007, all new ships over 300 gross tons and AIS equipment must be installed and all new passenger ships.
Through the mutual exchange of information among ships AIS system have enhanced mutual understanding through mutual exchange between ship and shore information to improve traffic management in the crowded waters through ships and between ships and between ship and shore Exchange security-related information to improve the safety of navigation.
Communication system designed to follow the principle of open systems interconnection, the International Organization for Standardization Open Systems Interconnection reference model (IS0/0SI) is recognized as an open system interconnection standards.
