Today’s cars already have hundreds of sensors and microprocessors, with advanced functionality like crash avoidance systems that can turn off cruise control and initiate “active breaking.” If cars with that sort of functionality could talk to each other, one car slowing down could prompt the one behind it to do the same. This kind of intelligence, which is the basis of the ITS (Intelligent Transportation System) could extend to an entire highway or apply to just one lane, where all of the cars drive on autopilot. (Aldirdge, 2012) Such an application could have huge potential to alleviate congestion. Another safety feature of the highway sensors would be its ability to tell how fast cars are driving, and could even relay information about speeders to the local police.
Connected Vehicles (by USDOT)
Connected Vehicles is a wireless communications network—a system among vehicles, infrastructure and personal communication devices. In this future network, vehicles can talk to each other and critical infrastructures. It can enhance safety by preventing crashes in advance, improve mobility thus ease the congestion as well as bring environmental benefits, and provide continuous real-time connectivity to all system users. Main features are as follows:
-Forward collision warning
-Intersection movement assist
-Emergency electronic backlight warning
-Blind spot warning
-Road weather motorist warning/ Real-time route-specific weather info
-Transportation management system
-Incident zone warning
-Cooperative adaptive cruise control
-Dynamic parking availability system
Land Airbus–Straddling Bus (by China TBS)
TBS China has unveiled the Land Airbus – a giant car-swallowing bus that could actually hit the streets of China. The vehicle can bend around corners, and it travels along rails to enable smaller vehicles to pass underneath.
This innovative urban transportation solution has a high-tech interior that is entered via a glass elevator that drops down at air lift stations. While passengers are getting on and off the vehicle, there is no hold up in traffic – cars just keep going under the Land Airbus.
Tran-z: Individual tram/underground systems (by Saketranz in India)
Tran-z is an automated underground transportation system, which runs on overheard track inside a small tunnel approx. 3 Fits radius (Like a big water supply pipe) powered by electric engine. These tunnels are laid few fits down the road. Tran-z runs into single track in circular way so it does not require track change as well.
Tran-z is collection of bogies/trolley, which could be many in numbers like 200+ or as per need of any city. Each bogie accommodates single person. Since Tran-z runs into a tunnel it is easy to construct and also does not interrupt ongoing traffic. Multiple Tran-z tracks can be constructed in small area/lane.
The technologies above have pointed out the value of co-operation among vehicles and between vehicles and the infrastructure, which is very likely to become the theme of the ITS in the future. Tomorrow’s driving assistance systems can go far beyond their present capabilities by implementing co-operation and information exchange in order to collectively perceive the context. The value of collaboration must not be underestimated and the need for making decisions dependent on the context is beyond doubt. (Gooderham, Mary, 2012) Designers of present-day driving assistance systems already have adopted some of the mechanisms of collaboration and context awareness, but it is still a long way to go until a fully collaborative context sensing system will be available to drivers.
