Measuring Freeway Road Traffic from the Skies

Skycomp wanted to replace the need to print out 1000's of traffic survey pictures so that "counters" could scan through the pictures and count vehicles, marking each picture with a grease pencil. A flash application was built to load the images in a viewer area with marking tools to replace the grease pencil. Different types of vehicles were marked with different symbols. Line tools were available to mark the stop and end of each count region. Comments could be assigned to each picture. The view area positioned images end to end to present a filmstrip style display. A thumbnail strip was available across the bottom of the screen to easily navigate to a specific image. All annotations were stored in a file that could be emailed back to Skycomp, enabling them to outsource the counting effort. The annotation file could be copied into a directory containing the same survey images, enabling a Skycomp administrator to replicate the results entered by the offsite "counter".
