Some possible solutions: * some kind of congestion pricing * private routes (Could be roads, rail, tunnels, etc. Charge for access.) * private vehicles (Could use existing routes or new routes.) * reduce traffic (by increasing costs, reducing the need, increasing number of people per vehicle, reducing vehicle size, separating people and goods) * make traffic more efficient (by providing status, prediction, or suggested routing) * make travel more personally productive The easiest solutions seem to be making travel more productive and reducing the need to travel. People stuck in traffic can consume music, news, lectures, advertising, etc. Sell something they can look at or hear. People stuck in traffic can get angry. Use that anger somehow. Give them an outlet to complain. Provide real-time traffic information, suggest routes, provide etas. Provide communication tech which reduces the need to travel. Conference calling, virtual presence. Help people to live without having to travel. The big solution to this is to build multipurpose real estate where people can work at or near their homes. Another way would be to deliver stuff to them. If your food were delivered to you, you wouldn't have to go out shopping for it. Physical mail should be digitized as much as possible. Efficiencies might be had by separating the transport of people and goods and by providing separate transport means. For example, why not deliver a family's daily food by robotic balloons or mini-robotic vehicles that can easily weave in and out of traffic? Web/phone services like craigslist that help people find what they want close to home would be useful. Smaller vehicles like segways might be very useful.
