Electric Car Fleets May Hold Promise for Improved Public Transit

The most effective way of reducing pollutants is through use of electric vehicles (EVs), which are approximately 97 per cent cleaner than petrol-powered cars.

The main disadvantages of public transport systems are the restrictions imposed on freedom of movement for their users travelling from outside the central and suburban business districts (CSBD). The use of a private motorcar provides a superior degree of freedom, with some restrictions on its parking location within the CSBD.

However, conventional petrol or diesel engine cars have been reported to be the main sources of urban air pollution in major Australian cities – pollutants such as carbon monoxide, oxides of nitrogen, sulphur dioxide, particles (up to 50 microns) and lead – as well as being considerable contributors to greenhouse gas emissions.

Some reductions in these emissions are possible either by improving the engine performance or by using alternative fuels (such as compressed natural gas, liquefied petroleum gas and hydrogen). However, the reductions are often only marginal and may come at a considerable cost. Improvements in the environmental impact of car emissions can also be made by introducing travel demand management (TDM) and the intelligent transport systems (ITS).


The bikes will make their debut appearance in Ed's new comedy TV show, 'Living with Ed' which broadcasts Sundays at 10pm ET/PT on HGTV.

The scooters top out at a 25mph speed, although the ones on loan to the Sheriff's Department are calibrated to travel no faster than 18mph.

Powered by advanced lithium-ion batteries and two 67bhp (50kW) electric motors to drive the front and rear axles, the Mixim is a four-wheel-drive car with a theoretical top speed of 112mph and a potential maximum range of 156 miles.
