Applied mathematics demonstrates that there is an optimal traffic density; exceeding this point reduces overall traffic flow and increases journey times for all drivers. Aggressive driving and frequent lane changes create disturbances that accumulate, worsening traffic conditions and increasing the likelihood of stop-start waves for everyone. Research indicates that even a small number of smoothly operating autonomous vehicles can significantly reduce these stop-start waves, improving overall traffic flow and fuel efficiency. Mathematics offers insights into preventing congestion by promoting smoother driving, consistent speeds, and coordinated decision-making within traffic systems, rather than just reacting to existing jams.
