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.

    Driverless cars will have a detrimental effect on congestion and security while the road safety benefits can be achieved sooner and cheaper using ADAS, argues Colin Sowman. Many Governments are consulting about the introduction of driverless vehicles and even running trials. As 70% or 80% of crashes are caused by human error, the promise of a crash-free future of driverless, self-driving or autonomous vehicles (call them what you will) is alluring, as are the claims of reduced congestion and lower emissions

    The American Road & Transportation Builders Association (ARTBA) has outlined a detailed proposal it believes could end the political impasse over how to fund future federal investments in state highway, bridge and transit capital projects. The ‘Getting beyond gridlock’ plan would marry a 15 cents-per-gallon increase in the federal gas and diesel motor fuels tax with a 100 per cent offsetting federal tax rebate for middle and lower income Americans for six years. The plan, ARTBA says, would fund a US$401 bil

    Dr Caitlin Cottrill, lecturer at the University of Aberdeen’s School of Geosciences, examines the impact of privacy legislation on the transportation sector. Growing reliance on big data, underscored by the increasing ubiquity of smart infrastructure and the ‘Internet of Things’, has profoundly impacted the regulatory environment experienced by transportation professionals. This is particularly the case in relation to the privacy of personally identifying information (PII). There has been increased attenti

    February 1, 2012
    The Netherlands has been looking at incentivising rush-hour avoidance. The intention is to better understand road users' motivations and find alternatives to congestion charging. Something significant needs to happen if we are to adequately address the traffic congestion and other issues caused by the ever-rising numbers of vehicles on our roads. Congestion or distance-based charging is seen as one way of managing demand and raising revenue for improvements to transport infrastructure. However, charging is
