Similar to a railway except that there are two suspended
cables, a few centimeters above the ground with the vehicle
riding above them.
The benefits are extremely fast installation vs. paved roads
which need heavy construction and massive changes to the
landscape and expensive maintenance.
automatically driven vehicles have a grip which slides
along the cable and releases the cable when reaching a
connection, junction or switch, gripping the next section with
an arm before letting go.
The vehicles can release from the cable system at designated
"sideways" where they then move on wheels to their destination
on regular roads driven by their drivers.
The wheel system is used for overtaking, changing "lanes" when
two or three roapways run alongside each other or stopping at
the ropeside (similar to roadside) for an emergency.
Making a roap-bridge is very easy, and enclosing a roap in a
translucent pipe, to avoid contact with pedestrians is simple
and costs much less than road construction.
Heavyweight supportive cables and "fast lanes" are all enforced
through the distributed software that allows for a reliable and
safe ride. Halfroaps - for ultra lightweight freight cars can be
used for personal mail sent over the system and reaching your
home or into the office at work. (riding up the side of the
With roaps there's no need for these wide roads
and you have more room for flowers grass and trees [pashute, Mar 19 2018]

||You might want to do some calculations as to lateral
accelerations during an interchange. Or is every
intersection a roundabout?
||Reality it seems. Maybe this is a doap inspired idea ?

[Pashute], Slow down a bit, take in the roadside flora.
||[+] Wotcha want is staggered posts on the two lines, then use a stepping motion to take advantage of the slacking of the cables, one wheel-bottomed leg then the other. At posts, just lift the leg that's at the top of its cycle.
