The assessment forms need Average Annual Daily Traffic (AADT) – Where do we get that information?
This is probably the most difficult part of the WABSA Project. Your local transportation department or planning department will be one source for AADT. Generally, AADT is only collected on busier streets because the planners/engineers are concerned with helping the traffic flow smoothly along that street. Give them a call and see if they have “traffic count” data for your project area roads. It might be on their website. It might be on your state Department of Transportation website. It might be available in paper maps or in notebooks. You’ll need to have a list of your roads with their start and stop cross-roads. If AADT is not available to you for some of your roads, try to set up a one-hour meeting with a traffic engineer or planner who wants to help your project. See if they can help you determine “approximate AADT” for your roads by studying the AADT of similar roads nearby (this process is also called “imputing” the data). Be sure you make note of which AADT came from real data a
