Here, why don't they just do this for cars....
China has done that a few decades ago, and it was phased out due to that traffic incidents inevitably will happen, and for untrained common people, fallen electric wires are a big risk.
Before those were phased out, we have a few hundreds electrocuted each year, some by crashing bus pulling HV lines down onto road, some by derailment breaking ground connection, some by just some conductive wires (wet kites, tree branches, etc.) touching HV lines.
This technology is good for trains and subways, where the environment is highly controlled. In open city roads, this has quite some potential safety hazards.
When I was in primary school, we were trained how to jump down a derailed bus with 2 feet in order to avoid step voltage. It's good that our next generation don't have to live with such danger.
I have done some research into electric roads & public autonomous podcars. see image .
pod-cars are slow as golf carts. because they are just 40kmh autonomous golf carts with automatic doors.
electric vehicles will always have a battery level problems with out charging on the move.
it looks like induction on the move is way too inefficient. and the large pick-up coils too heavy for most electric vehicles.
making allowances for vehicle ground clearances. makes electric induction way too inefficient.
electric roads will work as electric rail for podcars or electric vehicles that have dual modes.
electric vehicles that have dual road/rail capability. electric taxis & public autonomous transport pods
dual road/rail capability will work, also electric rail is very efficient and safe between A and B as the type of highway express lane.
for electric vehicles that have road/rail capability. is also the benefits of battery charging on the move at upto 150kmh.
to have road/rail capability on a road vehicle requires flanged wheels on the inside of the wheel rims.
as rails must be at the same level as the roadway and also the wheel radius of both rail flange, and road Tyre.
must have the same rotational speed at the outer radius. planetary gears are needed in the wheel hubs. so the two parts
of the wheel, so both rail flange, and road Tyre can have the same rotational speed. but also have shared drive and brakes systems.
power is supplied to moving electric vehicles on the rail expressway with a continuous overhead conductor running along the track
suspended from poles or towers or from structure or tunnel ceilings.
a robotic arm on the roof of the electric vehicle is the overhead power conductor. this robotic arm retracts whan in road/battery mode.
the transition from road to rail-expressway is period of transition by a ramp. the road Tyres are lifed of the road as the rails
contact the rail flanges on the wheels.
battery charging starts and the vehicle gos into 100% autonomous mode all while on the move.
two or more Rail gauges can be use on rail expressways but no railroad switchs.
so battery mode is how vehicles switch between electric expressways.
