Vehicle-related injuries may occur where they lose control of the vehicle or collide with another car(accident).Commercial truck drivers are an integral part of the African economy. Without truckers, few of us would be able to enjoy the access to the wide variety of groceries and consumer goods that we currently take for granted. Truck drivers regularly make a number of sacrifices in order to keep our economy moving. It is not rare for truckers to spend days at a time away from their friends and family. In addition, the nature of their job regularly subjects them to the risk of serious injury.
For the 83 biggest urban territories in the United States, activity results in exercise in futility and fuel esteemed at some $60 billion dollars. The World Health Organization assesses that more than one million passings every year are credited to air contamination, of which a vast extent is brought on by vehicular movement. The advantages of carpooling on an expansive scale are enormous. No one gets a kick out of the chance to sit in activity for quite a while. Each carpooling member takes another auto off the street, which implies less congested streets and expressways.
At the same time, traffic congestion has become a worldwide problem. This problem is mainly due to human driving which involves reaction time delays and judgment errors that may affect traffic flow and cause accidents. Engineers in the automotive industry put a lot of effort in devising systems which ensure safety in road vehicles. Even with all the advancements in vehicle safety technology, the number of people killed in auto accidents continues to rise. Close to 1.2 million people die each year on the world's roads and that number is expected to rise by 65 percent by the year 2020, says a report by World Health Organization (WHO) and the World Bank.
Safety is something that is kept on the top of the priority list and is the most important aspect of the designing phase. I automobile designing, the crash analysis defines the quality safety of the vehicle. Using different approaches including computer simulations, today the automobiles are safer and reliable. All this is only possible today with the advancement in computational power and the advancement in software development over the years. The foremost concern is the safety for the driver and the passengers.
Thus, individuals prefer the safe means of transport to avoid various accidents that might occur and as a result increasing the firm 's market share (Winston & Mannering, 2014). Reducing insurance liability The introduction of driverless cars could reduce the insurance liability paid by the individuals hence increased market share of the organization. The financial loss of the society and the economic costs of the insurance industry of road collisions are substantial. The benefits of the driverless cars are significant, and the insurance industry rewards and recognizes innovative technologies that enable vehicles safer (Vecchiato & Roveda, 2010). The automated cars encounter rare collisions since they are programmed to drive more safely than the humans and in the process causing minimal road accidents and therefore, less premium.
In control system design the modeling of a dynamic system is important as it represents the behaviour and characteristics of the system being controlled. In vehicle dynamic studies, the mathematical modeling of vehicle dynamic motion is done based on physical laws that describe the forces and moment acting on the vehicle body and tyres. The vehicle mode with steering system is drawn in Fig. 1. The equations of Vehicle dynamics are as follows: m( ˙vy + vxγ) = (Fx 1 + Fx 2)sinδf + Fy 3 + Fy 4 +(Fy 1 + Fy 2)cosδf (1) Iz γ˙ = (Fy 1cosδf + Fy 2cosδf + Fx 1sinδf + Fx 2sinδf)lf −(Fy 3 + Fy 4)lr + Mc (2) Mc = t w2 (Fx 1cosδf − Fx 2cosδf − Fy 1sinδf + Fy 2sinδf +Fx 3 − Fx 4) (3) The front wheel steer angle used in these equations is δf and is given by δ
The disadvantages of driverless cars By Johann Groß, Melinda Jakus, Denise Pizzimenti and Anko Baron Autonomous cars, defined as cars with the capability to act independently, are gradually appearing on the streets. The world is eagerly anticipating the full implementation of technology as advanced as this, but have managed to disregard the overwhelming disadvantages that come with any new technological advance. The problems with technological errors and its liability, the resulting ethics questions and the ever-existing human element, should prevent us from using this automated machinery. The point of this report is to present the disadvantages of driverless cars with the focus of technology, ethics and the human element. The chances that a vehicle might malfunction are much higher when the system used becomes more complex as the number of functions that could go wrong increases.
Vehicles enable our movement from place to place. Going to work, or school, a vehicle puts us in place for opportunity. It keeps us from walking, using a taxi, and just great for cutting time. If you happen to have a truck, you can haul furniture and appliances when moving from home to home. Think about it, our grandparents would have never come to see us without a vehicle.
Effects of Transportation on the local environment Transportation is like steroids! Steroids can help your muscle to develop faster but it can seriously damage your health. Likewise, transportation can help human civilization to grow but at the same time, it can cause great damage to our natural environment. Although different forms of transportation have made lives easier by letting people travel from place to place in ease, it also has detrimental effects on the local environment. For instance, it can cause major pollution on all water, land and air.
