I have survey for years what works and not. I've watched and compared. I would implement something like the German system similar to the Autobahn. All tractor trailers in only one lane and medium trucks in another and cars in one and emergency vehicles in other lanes and no more mixing all these vehicles in traffic. The bus routes are useless and should have a landing loop to not affect flowing traffic when buses pull over to drop/pick up passengers. You can have districts or pods to divide certain functions for that part of the city only or distribution centers for trucks. All trains should be on outter city limits and have specific shuttles from to and back to these public stations i.e., Train, Ship, airplane.. And all ways keep a designated road for all evacuations. The tolls should be paid as tokens different prices for different circulation of travel and limit areas of travel within one mile and have pod parking for the north, south, east and west of different pods in the city. Give tax breaks when we use public pods. The signs on the highways and road ways should all changed to show arrows to say your heading to east pod and then the district is changed into divisions by color...the entire state of florida has all green signs with white letters. I've witness one car going 45mph and a truck going 50 and then another car going 65 and it causes imbalance of speed and flow of traffic..we need to reduce the traffic lights to sectors of the pods within the city area. Once you have all the trucks in one distribution pod then the cars will flow in their lanes at easier commute. The list is long of my ideas i can write all day.
