Answer :
The most efficient way to address congestion and promote efficient usage is to impose a toll only on additional users beyond the optimal level of 100 per hour correct option is b.
To efficiently manage congestion on a bridge that becomes problematic after 100 vehicles per hour, the imposition of a toll on additional users exceeding this threshold is a strategic solution. Suggests targeting those surpassing the optimal capacity.
By implementing a toll for users beyond the 100 per hour limit, the system aims to incentivize alternative routes, modes of transportation, or off-peak travel times. This congestion pricing strategy not only helps regulate traffic flow.
It aligns with the broader goal of achieving a balanced and sustainable transportation system by mitigating congestion, reducing environmental impact, and enhancing overall efficiency in the use of critical infrastructure.
