Staggered Start - Use AI with traffic measuring to suggest best "time of departure"
Does every person have to show up exactly at 8 a.m.?? Staggered start could help to eliminate peaks by using AI with traffic metering.
On your marks, get set, go! If everyone arrives at the same time, this creates a huge peak. What if your start time was 8:15? What about 7:40? If every route was put into a computer, then it could be possible to determine your ideal time of departure.
Use text alerts to notify of departure times. If there are huge delays, suggest alternate routes. Maybe telecommute for 1 hour until that traffic jam clears?
