Cars provide mobility for billions of people around the world. For this to happen with maximum environmental compatibility, smart traffic management solutions and new utilization concepts will be required. Volkswagen is actively researching these topics and engaging with other companies and institutions in pursuit of ecologically acceptable forms of mobility for the future.
MOIA launches green service with whisper-quiet electric vehicles
MOIA is launching its highly efficient and flexible shuttle-on-demand service with environmentally friendly electric vehicles in Hamburg. This service complements the city’s local mass transit network and is set to become available to the general public in 2019.
And this is how it works: Customers can book the service via a smartphone app. They simply enter their location and destination and the MOIA vehicle arrives at a virtual stop no more than 250 meters away. The app navigates the customer directly to where the vehicle will stop and the service will likely cost less than a taxi.
The concept is based on the principle of ride pooling, where you share your journey with other customers travelling in a similar direction. An algorithm collates the journey requests, ensuring that the vehicles are used to optimum capacity and that customers do not have to wait for other passengers. “This principle benefits the environment in that people can leave their own vehicles at home, reducing the amount of traffic on the roads,” says MOIA press spokesman Christoph Ziegenmeyer.
Studies have shown that in big cities like Hamburg, private cars stand idle for more than 95 percent of the time on average (around 23 hours a day). Ride-pooling services offer an alternative which makes customers less reliant on their own cars. Pooling individual journeys makes more efficient use of the streets – not least because the downtown parking situation is eased, with fewer drivers searching for a parking slot. And if the shuttle vehicles are electric – as is the case in Hamburg – the environment also benefits from zero local emissions and very quiet running.
The MOIA electric vehicles have room for six people and a range-between-charges of around 300 kilometers (measured according to WLTP). Their empty battery can be charged to up to 80 percent capacity in about 30 minutes – providing the necessary level of everyday practicality.
Meanwhile, in Hanover, MOIA’s shared taxis have been in operation for some time now. The test phase involving 35 Volkswagen Multivan T6 vehicles was successfully completed in July 2018, since when anyone in Hanover can call up a MOIA cab.
Fewer journeys, zero local emissions and astonishingly quiet.
Up close and economical
In the course of 2018, MAN, DB Schenker and Fresenius University of Applied Sciences will be putting electronically connected trucks on the road. Digital communications keep the trucks at a steady distance. The aim is to cut fuel consumption and emissions, make better use of available road space and boost road safety.
Under the platooning principle, a number of electronically connected trucks follow each other at short distances, forming a convoy or “platoon”. Linked together by their vehicle-to-vehicle communication systems, the trucks effectively operate as a single unit. To take one example: if a situation occurs where the lead vehicle has to brake sharply, a brake sensor shares that information wirelessly with the other vehicles in the platoon, enabling them to brake simultaneously, with no time lag. The data is transmitted at a speed far exceeding human reaction times, which helps to reduce the risk of accidents.
As well as improving road safety, this technology also helps to protect the environment by reducing fuel consumption and emissions for the platoon as a whole by up to ten percent. This is down to what is known as the slipstreaming effect: the short distances between vehicles in the platoon reduce drag on all the vehicles traveling behind the platoon leader, which in turn means lower fuel consumption and CO₂ emissions.
During 2018, MAN will pilot-test semi-automated platoons on a section of the A9 motorway between Munich and Nuremberg known as the Digital Motorway Test Bed. A two-vehicle platoon will be used, comprising a driver-controlled lead truck and a second truck following close behind, whose driver will only intervene in the driving process if necessary. At platoon speeds of 80 km/h, the second truck will follow at a distance of just 15 meters.
Up to 10% reduction in CO₂ emissions.
Green lights for greener driving
Driver assistance systems help brake the car, change lanes and even pull into or out of a parking space. And they make for added safety, comfort and convenience. The “Intersection Pilot” can do even more: it helps not only the driver but the environment as well.
This is particularly important at busy major intersections, where CO2 emissions can peak. That’s where this Volkswagen research project comes in: The Intersection Pilot is connected to the traffic infrastructure in the shape of traffic lights, for example. This allows it to govern the speed of the car to ensure that, as far as possible, it doesn’t have to stop at the lights. And if a red light does proves unavoidable, the system governs the way the car slows down and then moves off again, to help as many following vehicles as possible to cross the intersection during the green phase.
For drivers, this means less time spent waiting and shorter tailbacks, while their cars consume less energy, reducing CO2 emissions into the bargain. One spin-off benefit is that traffic noise is also reduced, because accelerating from a standstill is a prime source of noise. The Intersection Pilot has already been tested in research projects with various partners and has emerged with flying colors. Before it can be successfully introduced, however, the traffic infrastructure must first be equipped with the necessary technology.
Intersections in particular offer great potential to cut CO₂ emissions.
