'Automated Highway System\r'

'As described and depicted in Sci-fi futuristic films like I, Robot, Minority trace and Star Wars, the Automated Highway system (AHS) features an automatically comptrollerled transportation system that is meticulously interlaced with the thoroughfare system.  The principal psyche of AHS is to remove the control operation from humankind control and assign it to the vehicle, which in criminal collaborates with the highway system to perform much(prenominal) function.Thus, the concept of AHS involves engineering science that thunder mug be classified into three groups namely, level-headed engine room on board the vehicle, intelligent technology in the road, and communication technologies that link or connect the vehicles to road.  Communication facilitates interactivity and information switch between vehicle and highway root word and action is undertaken by handlingr/ vehicle in an automated fashion.  (Ioannou, p183)AHS technology for vehicle auto-control ac centuates on how automobiles can routinely maintain road impulsive barriers especially some another(prenominal) vehicles, the track course, trading management rules, as well as internal engine problems so that the vehicle can instinctively make the proper steering, turning, braking, lane changing, fish fillet and other related movements involved in driving.The current trend under this aim is the blending of car and computer technology.  On-board PC promises latent flexible innovations which include meshing communications, car operation (sound, air-conditioning and navigating through voice) and paging, etcetera (The Economist)Current technology leading towards this end includes the intelligent cruise control system which use radar or laser to maven vehicles along its driving path that commands vehicle to decelerate or accelerate as needed or allowed; the driver attitude monitoring which reveals driver status i.e. disposition levels, stare direction, driving skill, etc. in another vehicle to warn other drivers on the road; collision apprisal that forewarns or notifies drivers for latent crash or collision accidents with other cars; navigation economic aid systems such(prenominal) as traffic and traveller information and on board diagnostics system that detects potential vehicle give way in advance, among others. (Cheon)AHS technology for highway control include traffic monitoring for traffic management, highway and incident surveillance technologies of which on that point are intrusive (pneumatic road tube, inducive loop detectors, piezoelectric sensors, magnetic sensors and slant in motion) and non intrusive technologies (video image processor, microwave radar, infrared, ultrasonic and passive acoustic set off sensors (Vehicle Detector Clearing House), and lane trailing and positioning, among others.Finally, technology for the seamless communication of the vehicle and road infrastructure is necessary for the integration, coaction and con nectivity of the system’s operations. The focus of interrogation on communications technology is the usefulness in the provision of real quantify, rock-steady data communications among vehicles and between vehicles and highway infrastructure.The global positioning system (GPS) is a promising technology for transportation communications for the fulfillment of AHS. It utilizes satellites rotating around the earth that woof up radio signals from users to calculate and mark their exact position including latitude, longitude and altitude. (Helms)The multifaceted potential benefits of AHS to the ordinary citizens, the transportation sector, and the general miserliness are both vast and profound. By removing the human component in driving and its penchant to errors, driving safety pass on be significantly improved. Factors such as fog, darkness and other severe put up conditions that can disturb visibility and immediately impact driving performance can be eliminated.Since d riving is automated, it affords populate loosen time for productive activities during travel such as studying and reading as well as leisure for playing, sleeping or relaxing.   For the elderly, the disabled and other people who do not know how to drive, driving skill is no more a hindrance to travel and mobility.    Travel time is also expected to be lessen because of free flow travel conditions as the traffic management system go out control and balance the speed of cars depending on the congestion of highway used at that time.
