Digi Technologies power zero-emissions London cab

US-based provider of machine-to-machine (M2M) and IoT connectivity products and services Digi International has supplied its Digi ConnectCore 6 (Digi CC6) system-on-module to drive Ecotive's Range Extended Electric (REE) Metrocab taxi – said to be the only zero-emissions-capable black cab currently operating in London.

US-based provider of machine-to-machine (M2M) and IoT connectivity products and services Digi International has supplied its Digi ConnectCore 6 (Digi CC6) system-on-module to drive Ecotive's Range Extended Electric (REE) Metrocab taxi – said to be the only zero-emissions-capable black cab currently operating in London.

The taxi's core powertrain and infotainment systems, which have been developed by Frazer-Nash Research, use the Digi CC6 to drive the Metrocab's entire driver instrumentation and passenger displays. Frazer-Nash utilises the module in processing information from the drivetrain to the instrument display and in providing wireless connectivity to deliver real-time information, application updates and a more interactive driver and passenger experience.

The taxi is driven by two electric motors with a 1-litre petrol engine coupled with a generator (the range extender) which charges the battery pack. Alternatively, charging can be achieved via any mains outlet, ensuring lower fuel consumption. This configuration, and the sophistication of the powertrain, allows the driver many charging options to maximise their efficiency. The Digi CC6 has been designed to prov

ide a fuller array of instrumentation, providing information on drive mode, speed, fuel economy and battery state of charge. It also provides trip information, distance, level of emissions and general information such as time, temperature, location via GPS and live weather reports.

The Digi CC6 also processes and powers an infotainment system that offers drivers Digital Audio Broadcasting (DAB) radio, FM radio, CD player, MP3, satellite navigation and an in-cab gaming system. For passengers, a rear display and wi-fi connectivity allow for smart phone mirroring and internet access. The rear display can also be used for location-aware advertisements, creating a new revenue source for taxi drivers.

    Temporary traffic monitoring with Bluetooth and wi-fi
    David Crawford reviews developments in temporary ITS. Widespread take-up of technologies such as Bluetooth and wi-fi are encouraging the emergence of more sophisticated, while still cost effective, ITS responses to the traffic issues posed by temporary road situations such as work zones and special events. Andy Graham of traffic solutions specialists White Willow Consulting says: “A machine-to-machine radio link is far easier and cheaper than reading characters on a plate.” There can be other plusses.

    Car parking and parked cars need not be a technological black hole
    David Crawford mines the potential of joined-up parking. Drivers conventionally see parking as an isolated, often frustrating, action; but collectively their attempts to find a space impact hugely on traffic flows. But new analyses of parking events look set to deliver real benefits to motorists and cities alike. Initiatives getting under way around the world are highlighting the advantages of connecting up parking events and – eventually - parked cars. The hoped-for results include not only enhanced urban

    Cellint measures speed and travel time without roadside infrastructure
    Collecting speed and travel time data without using roadside infrastructure could offer new possibilities to cash-strapped road authorities. Streaming video may be useful for traffic controllers to monitor incidents and automatic number plate recognition may be required for enforcement, but neither are necessary for many ITS functions. For instance travel times, tailbacks, percentage of vehicles turning, origin and destination analysis can all be done using Bluetooth and/or WI-Fi sensors and without video o
