It is a digital wireless device that sticks to the dashboard of any car. It has systems communications and GPS. It communicates with the human driver with a few navigation display lights; left, right, fast, slow indicators.
Thus we get the smooth traffic management system. Allowing run time congestion choices, pre-planned routes, automated convoys, virtual BRT lanes. We replace unrealizeable infrastructure plans. Rather distribute simple $50 device in each vehicle, and two extra pages in the DMV manual. That alone will reduce accident costs by a third. Increase transportation efficiency by a third. Probably generate $300 billion in yearly savings.
With a bit extra driver education, we get managed zones in which lightweights, BRT, and personal auto co-exist in harmony. As automation increases, there remains a $50 electronic pass for the human driver and his clunker. Electrics get virtual channels in space and time, for safety. Enabling electrics thus, generates an additional $100 billion in savings.
Other enabling. Easy insurance by the mile, raises driver awareness. Smooth pricing for various lane options at various times. Immediate identification with local traffic, plus warnings yields additional savings. Light synchronization with the digital devices is another benefit. Adding blinkers that send the signal from stop signs is priced near zero. Freight companies can adopt optimum fchannelized traffic routes, minimizing variances in speed getting optimum mileage. Pedestrians can carry a two dollar blinker.
The investment in fixed and mobile wireless network is only a few billion, but we get a few trillion in net present productivity in transportation.
The little dashboard device would be V shaped, as in V shaped recovery.
