Where the rubber hits the road
Roads, too, are a fixed system that can carry individuals
virtually anywhere. Believing we can pave our way out of the
congestion and gridlock, we have developed a high tolerance
for road expansion, one that is much higher than our tolerance
for rail expansion.

The Erasme Metro
station in Brussels, by Samyn and Partners,
is a combination of fiberglass and steel fabrics.
The fiberglass fabric is formed into posttensioned
saddles attached to arched steel
frames. The architects chose a stainless-steel
mesh, heretofore used only for sand separation
in quarries. It is durable and provides natural
ventilation.

Bus Rapid Transit (BRT), sometimes called a surface subway,
is not new. From Curitiba, Brazil, to Ottawa, Canada, communities
have invested in highly successful roadway transit systems
that use buses, separated in dedicated lanes, which have limited
stops at identifiable stations, where fare is collected prior
to boarding and service is frequent. Often cast as a substitute
for light rail, it has characteristics of both bus and rail.
Although it has dedicated lanes, they may either be physically
separate or instead may include right-turning or emergency
or other buses for some sections of the route. When the BRT
bus shares the public road, it often communicates directly
with the traffic signal system to get priority at intersections.
Deviations from the route or changes are easier to implement
with BRT than with fixed rails. New technology will further
distinguish it from its conventional rail and bus siblings.
This summer, Las Vegas will be the inaugural U.S. site for
the Civis bus rapid-transit vehicle manufactured by Irisbus
of France. Called MAX by its owner and operator, the Regional
Transportation Commission of Southern Nevada, it will have
all the features of other BRT systems except the driver is
aided by an optical guidance system, which uses cameras to
follow painted lines in the road. For a vehicle in a dedicated
lane, the guidance system keeps the bus on its course. There
is a driver who can take over controls with the touch of the
hand. Because MAX will share the road with other vehicles,
the optical guidance system will be used for precise docking
at each station. MAX will stop each time at the same place
in front of the whimsical new shelters designed by Assemblage
Studio Architects of Las Vegas.
