Swedish geographic modelling specialist Blom and Finnish company Suomen Kuntotekniikka are cooperating on road condition assessment projects using BlomSTREET imagery to enable visual assessment of roads requiring repairs and providing budgetary analysis of the maintenance and construction tasks.

BlomSTREET imagery provides automatic traffic sign inventory using official traffic sign libraries. The company says recent projects demonstrate that the automatic method provides a completion of better than 90% of an inventory project. Problems caused by dense vegetation, partial signs and other intrusions can be improved using manual editing.

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

    David Crawford investigates progress in a key safety area - work zones. Highway construction zone safety is taken seriously enough in the US to merit a special spring National Work Zone Awareness Week, which in 2010 ran from 19-23 April. Headed by the US Department of Transportation's Federal Highway Administration (FHWA), this aims to reduce an annual toll of work zone deaths - 720 in 2008 (an average of one every 10 hours) with more than 40,000 traffic injuries (an average of one every 13 minutes).

Installation began in 2004, and the result will represent a large-scale and highly exportable solution to the need for harmonisation of traveller information in urban regions with multiple transport operators.
