The Night Shift

The FlexStreets engine uses these categories and assigns a certain percentage of each roadway to each vehicle type, based on a set of variables. Key variables include time of day, realtime traffic patterns, consumer demand, current weather, and day of the year. Late at night, the majority of the roadway is given to Heavy and Medium vehicles such as sanitation trucks, delivery vehicles, and passenger buses, while very little is set aside for Ultralight vehicles. In a typical weekday, the road use is shifted during the first few hours of the day to be more focused towards commuting, so the proportions favor vehicles that serve that purpose. 

This includes Medium, Light, and Ultralight vehicles -  such as self-driving shuttles and buses, and light personal transportation devices like scooters.  In the middle of the day the majority of the roadways are dedicated to Self-Powered modes to allow for peaceful recreation, farmer’s markets, reduced pollution, etc. Then in the evening the use shifts back to favor commuting but with a continued emphasis on Ultralight vehicles to give space to people jogging, exercising, and socializing. Then, later at night, the cycle starts all over again. 

This animated diagram shows how the traffic percentages shift over the course of a typical day.
