Back in March I wrote about forecasting hourly volumes for signal warrants from forecasted daily traffic volumes. It's come to my attention that PC-Warrants has a tool built in it that makes the process very easy. If you have PC-Warrants, search under "Volume Data Wizard – ADT to Volume Converter."
