The best way to design a study to determine how much traffic there is during the morning rush hour along a city street would be to:
**Make video recordings of the street during rush hour every day for a year and count the numbers of vehicles that pass a certain point.**
This method allows for accurate, consistent, and comprehensive data collection over an extended period, capturing variations in traffic patterns due to factors like weather, special events, and other variables. It also minimizes biases that could arise from self-reported data, as would occur in the other survey-based approaches.
