Traffic is lighter in the summer and around the holiday breaks. Kids used to walk/bike to school in greater numbers but parents are disinclined to send them off nowadays. There are a number of ways to get kids walking and biking to school again which could reduce traffic during the AM commute times, it starts with safety education. Programs like UM's Bikesafe/Walksafe programs have made walking and biking safer for youth. Encouraging parents to join their kids and start their day with a healthy walk/bike can reduce stress and prepare young and older minds for the day ahead. Schools are usually nearby the students home within walking/biking distance, and creating a sense of safety and encouraging this trip to be active could be very helpful.
The FDOT is actually studying this as part of the Biscayne Blvd (US-1 Master Plan). This could be very beneficial and provide opportunities for protected bike lanes and separate bus lanes without sacrificing travel lanes. It would also signalize all the intersections so lights could be timed to improve flow as well.
