Vehicular communication systems. Generally, vehicular networks are considered to contain two types of nodes: vehicles and roadside stations. Both are dedicated short-range communications (DSRC) devices. DSRC works in 5.9 GHz band with bandwidth of 75 MHz and approximate range of 1000 m.[1] The network should support both private data communications and public (mainly safety) communications but higher priority is given to public communications. Vehicular communications is usually developed as a part of intelligent transportation systems (ITS). ITS seeks to achieve safety and productivity through intelligent transportation which integrates communication between mobile and fixed nodes.
To this end, ITS heavily relies on wired and wireless communications. Motivation[edit] The main motivation for vehicular communication systems is safety and eliminating the excessive cost of traffic collisions. Although the main advantage of vehicular networks is safety improvements, there are several other benefits. Development[edit] Forget Driverless Cars: Driverless Bus Will Hit Swiss Roads In 2016. CarPostal contracted Bestmile for shuttles that can carry 9 passengers. The company will be field-testing the vehicles in the city of Sion, Valais. (Photo : Bestmile) Driverless cars are the talk of the automotive industry at the moment.
However, a car, is just that, a car. An EPFL (Ecole Polytechnique Fédérale de Lausanne) spinoff company, Bestmile, is looking to up the ante by launching the driverless bus in the streets of Switzerland. That's right, a bus. Bestmile started developing the driverless electric bus a couple of years ago through the initiative of its founders, Raphael Gindrat and Anne Koysman, both are products of EPFL.
"The algorithms developed with the EPFL will take into consideration all the different scenarios that autonomous vehicles can find," Bestmile explains. Within the next two years, the buses will be field tested as autonomous shuttles in Sion, a city within Valais. . © 2015 Tech Times, All rights reserved.

All the Accidents California's Driverless Cars Got in by Being Too Good at Driving. Autonomous truck cleared to drive on US roads for the first time. (Image: Daimler AG) The next big thing in autonomous vehicles really is big. At a ceremony at the Hoover Dam last Wednesday, automotive manufacturer Daimler unveiled a self-driving truck – the first to be cleared to drive on US roads.
For the freight industry, the Inspiration Truck holds the promise of a future with fewer accidents, lower fuel costs and well-rested drivers. Over the past few years, autonomous trucks have drawn the attention of companies that repeatedly use the same routes or encounter few people or other vehicles. Some farms use autonomous grain harvesters or planters.
Mining company Rio Tinto has more than 50 self-driving vehicles hauling iron ore at a remote site in Western Australia. In Texas, the US military has been working on trucks that can navigate battle zones. The Inspiration is different, designed to travel on the highway alongside regular cars and trucks. Autonomous convoy Autonomous trucks have a few potential advantages over their hands-on counterparts. The Little-Known Robot Taxi That Could Outrun Google and Uber. The View from the Front Seat of the Google Self-Driving Car, Chapter 2. Summer is one of the most dangerous times of the year on U.S. streets, as many of us spend more time behind the wheel, heading out for long road trips or local barbecues. The AAA Foundation for Traffic Safety, for example, has declared the period between Memorial Day and Labor Day to be “The 100 Deadliest Days” for teenage drivers — and they’re not on the roads alone.
Statistics like this keep my team and me working hard on a fully self-driving car that can get you from A to B safely, no matter how many beverages you have by the pool or how many texts you send to the new friend you met there. Our self-driving cars are being hit surprisingly often by other drivers who are distracted and not paying attention to the road. That’s a big motivator for us. The most recent collision, during the evening rush hour on July 1, is a perfect example. One of our Lexus vehicles was driving autonomously towards an intersection in Mountain View, CA. You can find chapter 1 here. Google's Plan to Eliminate Human Driving in 5 Years. Google’s adorable self-driving car prototype hits the road this summer, the tech giant announced last week. Real roads, in the real world. The car has no steering wheel or pedals, so it’s up to the computer to do all the driving. As cool as this sounds, it isn’t a huge technological step forward.
The goofy little cars use the same software controlling the Lexus and Toyota vehicles that have logged hundreds of thousands of autonomous miles, and Google’s spent the past year testing its prototypes on test tracks. What’s important here is Google’s commitment to its all-or-nothing approach, which contrasts with the steady-as-she-goes approach favored by automakers like Mercedes, Audi and Nissan. Autonomous vehicles are coming. “We call it a revolution by evolution. Google thinks that’s exactly what’s going to happen. Click to Open Overlay Gallery In the past few years, Google has used about two dozen modified Lexus RX450h SUVs to drive nearly a million autonomous miles around Silicon Valley.
Autonomous long-distance drive. The Driverless Cars of Greenwich. Google driverless car. States that allow driverless cars public road testing. In addition, a law proposed in Texas would establish criteria for allowing autonomous motor vehicles. Toyota Prius modified to operate as a Google driverless car driving a test course.[1] The U.S. state of Nevada passed a law on June 29, 2011 permitting the operation of autonomous cars in Nevada. Google had been lobbying for robotic car laws.[5][6][7] The Nevada law went into effect on March 1, 2012, and the Nevada Department of Motor Vehicles issued the first license for an autonomous car in May 2012. Technology[edit] Google's robotic cars have about $150,000 in equipment including a $70,000 LIDAR (laser radar) system.[12] The range finder mounted on the top is a Velodyne 64-beam laser.
Road testing[edit] On March 28, 2012, Google posted a YouTube video showing Steve Mahan, a Morgan Hill California resident, being taken on a ride in its self-driving Toyota Prius.

Google’s latest self-driving car prototype has headlights, but no steering wheel or pedals. Google The self-driving, goofy-looking car with no steering wheel or pedals that Google revealed in May is now “fully functional” and should start testing on public roads next month, the tech giant says.
Over the past seven months, Google has made a series of prototypes, testing different aspects of the design, from steering and braking to the sensors and software that brings it all together. The result, it says, is “our first complete prototype for fully autonomous driving.” In contrast to the gradual approach to autonomous driving advocated by automakers like Audi, Mercedes-Benz, and General Motors, Google is going for what it calls a “moonshot.” In the next five to 10 years, it plans to introduce a car that’s so over the idea of human drivers, it won’t even come with a steering wheel or pedals. The new version doesn’t look too different from the one we saw in May. Here's How to Get Rid of Traffic Jams. We have HOV lanes (or carpool lanes as we call them) and now also have HOT lanes in Los Angeles, and they can help, but during rush hour it's a crap shoot, especially the non-toll carpool lanes.
All it takes is one slow driver who decided to get in just because they've got other people in the car to ruin it for everyone else. And some people will just assume they can speed through, even though even the carpool lane can get jammed. I once saw an accident on the 405 (north, near LAX) in the carpool lane - traffic had slowed, like it always does on the 405, and a car slammed into the back of another one because they didn't notice and started hitting the brakes too late. Parts of the 110 and 105 were turned into toll lanes but you can get in them free if you have 2 or more people in your car (or 3 or more if that's the requirement). Another technology that could make traffic jams go away: a car mounted disintegration beam, but only on my car. Flagged. Toyota Joins Slew of Major Automakers Promising Self-Driving Technology This Decade. Toyota recently added its voice to a chorus of major automakers promising self-driving systems when the firm announced it would offer a car with “automated driving technologies” by the mid-2010s.
In recent months, several manufacturers—Tesla, Nissan, BMW—have published forecasts of robot cars inside the next decade. Toyota, the latest to promise automated car tech, is more modest than some of its competitors. The Japanese firm’s Automated Highway Driving Assist (AHDA) system is, as the name suggests, for highways only. Once available, the system will keep the car in its lane using cameras and radar and maintain a safe following distance by wirelessly transmitting acceleration data to nearby cars. Similar features (though not yet as automated as Toyota’s promised tech) are already available in high end cars like the 2014 Mercedes S-Class. However, the S-Class maintains following distances using radar and cameras.
But what each firm is forecasting as “self-driving” varies.
