An article puiblished several years ago suggested the following ideas as solutions to traffic jams. From today's perspective, do these ideas work?

1. a guiding system with smart sensors which indicate whether a parking spot is occupied or empty  
2. wireless vehicle-to-vehicle communication, your car may monitor the motion of a vehicle five vehicles ahead and prepare for what is going to happen
3. smartphone app which works like a social network for drivers
4. motivating people to travel in off-peak hours  
5. a driverless car, automated driving in cities allows for much denser packing of cars in streets
6. a great public transport system with extra bus lanes, nicer train stations and on-board wi-fi
7. use of waterways as an infrastructural resource for public transport
