According to the IEEE, the world's largest consortium of technical experts, almost every accident is caused by the fault of the driver. If existing intelligent traffic technology can be applied to cars and roads, up to 90% of accidents can be avoided. These technologies include electronic and computational technologies such as vehicle-mounted vision systems and sensors that can sense fatigue, lane departure warning systems, and communication systems for cars and cars and infrastructure for safety applications. However, in order for the general public to afford these safety devices, the cost needs to be further reduced.
IEEE member, Dr. Azim Eskandarian, director of the George Washington University Intelligent Systems Research Center, said: “Advanced embedded systems, sensors, microprocessors, and control technology today have helped make vehicles and roads safer, but integrating these technologies into vehicles. However, it can be expected that in the next 10 years, with the continued reduction in technology costs and the gradual increase in the application of these technologies, we can see significant improvements in vehicle safety, efficacy, and energy conservation. , especially in those developing regions, although the public there is still unable to afford high-end cars."
Dr. Eskandarian also pointed out that other challenges include market acceptance and potential technology-related responsibilities, such as driver assistance programs such as collision prevention and automatic braking, which can control the vehicle in whole or in part. However, the realization of these technologies is likely to be like the original airbags and the implementation of the ABS or ESC. It was initially only available as an optional feature but is now used as a general safety measure. Used in almost all vehicles.
Advanced research in safety technology has gone far beyond single vehicles. For example, Teruo Higashino, an IEEE senior member and professor of the Information Network Department at Osaka University in Japan, is currently studying applied wireless network technologies that can be used in inter-vehicle communication systems to help detect dangerous vehicles on the road, for example, a vehicle that is approaching a blind spot at an intersection. It can alert drivers in the vicinity and drastically reduce the accident rate. Many of these pioneering innovations, including the communication system between cars, were mentioned at the recent IEEE Intelligent Transportation Conference held in Washington, USA.
Dr. Alberto Broggi, president of the IEEE Intelligent Transportation Systems Society and a professor at the University of Parma, Italy, pointed out that the upcoming intelligent transportation technologies, including self-driving vehicles, will change our concept of automotive use forever. Dr. Broggi recently successfully managed to complete the travel of 13,000 kilometers of unmanned vehicles from Italy to China. He said: "These unmanned vehicles will be used outside the metropolis for the next 5 to 8 years. The same technology will also be applied to agricultural equipment, including self-driving tractors and combine harvesters. Maximize land use, increase crop yields, and reduce damage."
Another benefit of intelligent transportation technology is to reduce vehicle fuel consumption and exhaust emissions. Matt Barth, a senior member of the IEEE and a professor at the University of California at Riverfront Center for Environmental Studies, predicts that the use of eco-friendly intelligent transportation technologies such as “eco-paths†will reduce fuel consumption and exhaust emissions by 20-30% worldwide in the next five years. Through the vehicle's GPS system allows the driver to select the driving route based on the minimum fuel consumption.
Dr. Barth stated: "Many governments are setting standards for fuel consumption and exhaust emissions for new automobiles in the coming decade. Integration of ecological and intelligent transportation technologies, such as the integration of ecological pathways into vehicles, will further reduce carbon emissions and achieve more efficient fuel efficiency. To increase energy self-sufficiency."
Kyongsu Yi, director of the Vehicle Dynamics and Control Laboratory at Seoul National University in South Korea and an IEEE member, pointed out that the application of ITS is different due to installation. He said: “In European and Asian countries, some cities are designed according to the traditional thinking around a relatively small and defined city center. They value the traffic management system established for the protection of pedestrians. The United States has a wider open space. The research focus is on avoiding rollovers or vehicle safety systems that collide with other fast-moving vehicles."

The masonry bit is a variation of the Twist Drill Bit, the bulk of the Tool is a relatively soft steel, and is machined with a mill rather than ground. An insert of tungsten carbide is brazed into the steel to provide the cutting edges.
Masonry bits typically are used with a Hammer Drill, which hammers the bit into the material being drilled as it rotates; the hammering breaks up the masonry at the Drill Bit tip, and the rotating flutes carry away the dust.
Hammer drill bits often use special shank shapes such as the SDS type, which allows the bit to slide within the chuck when hammering, without the whole heavy chuck executing the hammering motion.
Masonry bits of the style shown are commonly available in diameters from 3 mm to 40 mm. For larger diameters, core bits are used. Masonry bits up to 1,000 mm (39 in) long can be used with hand-portable power tools, and are very effective for installing wiring and plumbing in existing buildings.
