This paper describes the first results of R&D project "Intelligent Street" carried out in Finland. The aim of the project is to develop new measuring and design methods and tools for street design and construction. Usability and accuracy of laser scanning technology was tested in field-tests done in Itäreimarintie street pilot in Helsinki area June 2003. Implementations of measurements using helicopter based 3-D laser scanning technique are presented and evaluated.
