Swedish geographic modelling specialist Blom is cooperating with a Finnish company, Suomen Kuntotekniikka, on road condition assessment projects, using BlomSTREET imagery which enables visual assessment of road segments where repairs are required, providing budgetary analysis of necessary maintenance and construction tasks.

BlomSTREET imagery provides automatic traffic sign inventory using country-specific, official traffic sign libraries. The company says that experience from recent projects demonstrates that the automatic method provides a completeness of better than 90 per cent for an inventory project.  Problems caused by dense vegetation, partial signs and other intrusions can be improved using manual editing.

A standard traffic sign inventory project includes capturing coordinates (x,y,z) and orientation of the sign, standard deviation, sign type and any text contained on the sign itself.  Once images have been captured for inventory and assessment purposes they can then also be used for many alternative functions, such as city planning and 3D modelling.

"The high quality BlomSTREET imagery has been a great tool for interpreting the condition of streets. Together with ground-penetrating radar data, it allows quick identification where streets are in need of repair,” states Jari Marjeta of Suomen Kuntotekniikka.

    Elmar Brockfeld, Alexander Sohr and Peter Wagner from the German Aerospace Center's Institute of Transport Systems look at the prospects for floating vehicle data systems. Although Floating Vehicle Data (FVD) or probe vehicle fleets have been around for about a decade, the idea behind them is of course much older: from probe vehicles that flow with the traffic it should be possible to get a precise, fast and spatially near-complete picture of the prevailing traffic flow conditions in an area under surveilla

On the 24th March 1999, a Belgian truck transporting flour and margarine through the 11.6km Mont Blanc tunnel caught alight when a cigarette stub entered the engine induction snorkel, lighting the paper air filter. The fire left over 30 dead and many more injured. At the time, the Mont Blanc tunnel disaster was the world’s worst tunnel fire.
