Pluto pictures highlight satellite potential

Along with many others on planet Earth, I have been captivated by the amazing images of Pluto’s surface captured by NASA’s New Horizons spacecraft and sent back across some 4.3 billion kilometres (2.7bn miles) of space. The capture and transmission of such detailed images highlights the progress in the whole area of satellite technology and prompts the mind to contemplate the potential that the increasing number of earth-orbiting satellites could hold for the transport sector.

Along with many others on planet Earth, I have been captivated by the amazing images of Pluto’s surface captured by NASA’s New Horizons spacecraft and sent back across some 4.3 billion kilometres (2.7bn miles) of space. The capture and transmission of such detailed images highlights the progress in the whole area of satellite technology and prompts the mind to contemplate the potential that the increasing number of earth-orbiting satellites could hold for the transport sector.

As this issue of ITS International illustrates, satellite technology is already influencing the ITS sector – as exemplified by Slovakia’s truck tolling system which covers 40% of its roads, divides them into 4,000 segments and was set up in under a year. Compared with traditional tolling systems that require large infrastructure investments, satellite-based systems are quick, easy and relatively cheap to deploy and are also extremely flexible.

This combination of flexibility and low capital investment (at ground level at least) and the ability to uphold the ‘user pays’ principle, opens up opportunities for cash-strapped national and regional authorities.

Authorities could use the technology to implement vehicle tolling while also mitigating the disincentives suffered by rural communities and the regressive effect of fuel taxes on less well-off households with older and less fuel-efficient cars. They would have the means to tailor toll charges to suit the myriad of road and vehicle types as well as the location (urban/congestion charge or rural) and time of day/day of the week and so on.

Furthermore, satellite technology can contend with cross-border journeys without interoperability problems and even accommodate a number of motorists’ profiles - for instance a doctor on a call-out or driving their car for private use. 

If thoughtfully implemented with the appropriate privacy safeguards (possibly a prepay card in the onboard unit making ‘tracking’ unnecessary) a satellite-based system could overcome many of the public’s objections to tolling. And if used in place of (rather than in addition to) existing taxes, licences or fees, objections to tolling existing roads could even be silenced. Public approval would then come down to a matter of setting the appropriate toll charges. 

Will a national or state authority have to courage to ‘boldly go’ where no authority has gone before? 

Yes – eventually; because funding shortfalls will force such implementations.

    The increasing capability of satellite navigation is helping vehicle manufacturers and local authorities as well as individual drivers and fleets. In comparison to the physical ITS infrastructure in towns and cities and on motorways and highways, satellite navigation (satnav) systems have come a long way in a short time. Many (if not the majority) individual drivers and fleets use or have access to a satnav and now the vehicle manufacturers and even local authorities are beginning to utilise satnav derived

For example, you would pay a set amount in exchange for a monthly travel package covering up to 100km of free taxi journeys in your home city (including a guaranteed 15 minute pickup) and public transport usage within a 1,500km radius of your home. Not only would this option be cheaper than owning and maintaining your own car, you would

Colin Sowman speaks to one woman about the practical benefits - and difficulties - of getting out of her car and switching to public transit in Atlanta, Georgia One of the first goals of Mobility as a Service (MaaS) inventor Sampo Hietanen is that MaaS should persuade households they don’t need a second car. This is starting to happen - even in the car-dominated US. Last year, authorities in the state of Ge

    Perceptions of machine vision being an expensive solution are being challenged by developments in both core technologies and ancillaries. Here, Jason Barnes and David Crawford look at the latest developments in the sector. A notable aspect of machine vision is the flexibility it offers in terms of how and how much data is passed around a network. With smart cameras, processing capabilities at the front end mean that only that which is valid need be communicated back to a central processor of any descripti
