In the current scenario the world is plagued by accidents which are primarily due to human errors in judgment and hence thousands of lives are lost. These accidents can be avoided if only there was a mechanism to alert the driver of approaching danger. This can be done by monitoring the distance between nearby cars and alerting the driver whenever the distance becomes too short. This is precisely the aim of this paper. In this paper we propose the use of Bluetooth Technology by which we can check the speed of the car whenever it comes dangerously close to any other vehicle up front, thereby saving very many lives.
Vehicle Traffic Monitoring Platform with Bluetooth Sensors over ZigBee:
The Vehicle Traffic Monitoring Platform from Libelium allows system integrators to create real time systems for monitoring vehicular and pedestrian traffic in cities by using the new Bluetooth - ZigBee double radio feature available in the Waspmote sensor board.The new Vehicle Traffic Monitoring Platform, part of the Libelium Smart Cities solution. The platform is capable of sensing the flow of Bluetooth devices in a given street, roadway or passageway differentiating hands-free car kits from pedestrian phones. Sensor data is then transferred by a multi-hop ZigBee radio, via an internet gateway, to a server. The traffic measurements can then be analysed to address congestion of either vehicle or pedestrian traffic.
Understanding the flow and congestion of vehicular traffic is essential for efficient road systems in cities. Smooth vehicle flows reduce journey times, reduce emissions and save energy. Similarly the efficient flow of pedestrians in an airport, stadium or shopping centre saves time and can make the difference between a good and a bad visit. Monitoring traffic - whether road vehicles or people - is useful for operators of roads, attractions and transport hubs.
The monitoring system can also be used to calculate the average speed of the vehicles which transit over a roadway by taking the time mark at two different points.
Top 10 Advanced Car Technologies by 2020
Attending CES and the Detroit auto show over the past two weeks has my brain is awash in future technology. Mercedes-Benz showed off its fully autonomous F015 Luxury in Motion concept car in Las Vegas, while Buick, Chevrolet, Hyundai, Infiniti and Volkswagen all had concepts sporting advanced features in Motown. Many of these technologies are a ways off, but others are just around the corner, or even entering showrooms right now. The rate at which technology is changing personal transportation accelerates every year, which can make predicting the arrival of future car tech a dicey proposition. Even more compelling is the increasing priority we’re seeing consumers place on automotive technology during their shopping process at Kelley Blue Book. This had me wondering — what automotive technologies will go from science fiction to commonplace in just the next 5 years. I’ve listed these below in an effort to identify the top 10 advanced car technologies we’ll see in showrooms by 2020.
1. Autonomous Vehicle — Let’s just get this one out of the way. Note I didn’t say fully autonomous vehicle. Why? Because it will take more than 5 years before a car can drive anywhere, at all times, without human oversight. But by 2020 we’ll have cars capable of being fully autonomous in certain circumstances, most likely rural interstates with minimal variables (and no inclement weather). Think early days of cruise control.
2. Driver Override Systems — This relates to autonomous technology, but it’s different because it’s the car actively disregarding your commands and making its own decisions. We’ve already got cars that will stop if you fail to apply the brakes. But by 2020 cars will apply the brakes even if the driver has the gas pedal floored. The rapid increase in sensor technology will force a shift in priority, giving the car final say — not you.
3. Biometric Vehicle Access — The switch we’ve seen in recent years from keys to keyless entry and start will be followed by a switch to key-fob-less entry and start. You’ll be able to unlock and start your car without anything more than your fingerprint (or maybe your eyeball, but fingerprint readers are more likely than retina scanners). Sound a lot like the latest form of cell phone security? It should, because it’s exactly the same concept.
4. Comprehensive Vehicle Tracking — Insurance companies, and some state governments, are already talking about fees based on how many miles a person drives. By 2020 insurance companies will offer a reduced rate for drivers that agree to full tracking of their behavior. I’m hopeful this technology remains voluntary, but do I foresee a likely future where insurance companies will require comprehensive driver tracking? Sadly, yes.
5. Active Window Displays — Head-Up Display (HUD) technology has come a long way from the dim, washed out green digits some cars projected on their windshields 20 years ago. But as good as HUD is in 2015, by 2020 we’ll see active glass capable of displaying vibrant images. Imagine a navigation system that actually highlights the next turn (as seen from your perspective, through the windshield) as you approach it.
6. Remote Vehicle Shutdown — This technology already exists, with OnStar leveraging it regularly. In recent years the telematics company has shut down hundreds of stolen cars, ending police chases quickly and with little drama (though most drivers still don’t know it can be done, even drivers with OnStar…). By 2020 remote vehicle shutdown will enter the social consciousness, negatively impacting nightly news ratings everywhere.
7. Active Health Monitoring — Ford Motor F -0.91% Company has previewed the idea of seatbelt or steering wheel sensors that track vital statistics, though the rapid development of wearable technology means most cars will just wirelessly pair with these devices (think cell phone for your body). Combine this with basic autonomous technology and you’ve got a car that can pull over and call paramedics when the driver has a heart attack.
8. Four-Cylinder Supercar — Ford just showed an all-new GT supercar using a twin-turbo V6. While it may rub traditional performance enthusiasts the wrong way, a lightweight V6 making over 600 horsepower will offer world-beating performance, especially if it’s got a light, carbon-fiber body to pull around. By 2020 we’ll see the first full-fledged, 200-plus mph supercar with a four-cylinder engine (cubic inches be damned).
9. Smart/Personalized In-Car Marketing — You’re already getting Facebook, Twitter and Gmail ads based on your behavior. By 2020 the average car will be fully connected to the internet, meaning your vehicle will provide marketers with a powerful set of metrics to customize their message. Hopefully these will manifest as an opt-in feature, but get ready for personalized, location-based ads in your car’s display.
10. Reconfigurable Body Panels — The small SUV category is seeing increased demand these days, while truck sales grow by leaps and bounds. What if you could have both vehicle types in one car? Imagine an SUV with lightweight body panels and advanced motors that retract the roof and side glass into the lower body panels. Now throw in Chrysler minivan stow-and-go seat design and BAM! A truck and SUV in one vehicle. It could happen.
