There are several alternative policies that governments could implement to reduce traffic. Some of these include:

1. Invest in public transport: Governments can invest in improving public transport infrastructure, making it more convenient, affordable and reliable. This could encourage more people to use public transport instead of driving.

2. Implement congestion charges: Governments can introduce congestion charges for drivers who enter congested areas, particularly during peak hours. This can help to reduce traffic congestion and encourage people to use public transport or other forms of transport.

3. Encourage carpooling and shared mobility: Governments can encourage carpooling and shared mobility options such as bike sharing and car sharing programs. This can reduce the number of cars on the road and decrease traffic congestion.

4. Implement parking policies: Governments can introduce policies such as reducing the availability of parking spaces or increasing parking fees to discourage people from driving their own cars.

5. Promote active transport: Governments can promote walking and cycling as alternative modes of transport, by investing in infrastructure such as bike lanes and pedestrian walkways.

6. Improve urban planning: Governments can improve urban planning by designing cities that are more walkable and bike-friendly, and by locating workplaces and amenities closer to residential areas. This can reduce the need for people to commute long distances by car.

7. Encourage remote work: Governments can encourage remote work policies and provide incentives for companies that allow their employees to work from home. This can reduce the number of people commuting to work by car.

Overall, there are a variety of policies that governments can implement to reduce traffic, depending on the specific circumstances and goals of the government or society.
