Challenge Problems
Push your limits with advanced challenges
In a traffic simulation, the density is observed to be 80 vehicles per km. If a new regulation permits a minimum distance headway of 15 meters, is this acceptable?
💡 Hint: Figure out the spacing and compare it to regulations.
If you were an engineer tasked with redesigning a section of road with high traffic density, how would you address the issue of distance headway to improve safety?
💡 Hint: Think about physical changes that can lead to safer driving distances.
