Use a supply and demand diagram to help explain how a city council might help to decrease traffic congestion in the city during weekends.

• pointing out that demand happens during a peak period
• and that perhaps one could enhance demand during off-peak periods - say by lowering parking prices
• lowering demand during weekends

a) toll booths at city limits

b) creating viable and attractive substitutes, for example by enhancing bus runs and/or lowering the price of public transportation

c) Make parking houses outside city limits with free buses into the city centre

• other solutions in lowering demand, for example each other weekend only odd number license plates in the city
• Enhanced road tax
• any plausible example of how weekend driving in the city might be reduced
