SHORT DISTANCE CLASSICS Escalators and elevators are primari ly known from buildings but they can also serve as a means of public trans portation Portugal s hilly capital Lis bon for instance has elevators that connect neighborhoods at higher and lower elevations with each other The Central Mid Levels escalator in Hong Kong is an 800 meter 2 600 foot long system traversing an impressive elevation of 135 meters 443 feet from bottom to top used by about 100 000 people per day In the poor Comuna 13 neighborhood in Medellín that like many others grew on a steep slope several escalators with a total length of almost 400 meters 1 312 3 feet were built a few years ago Horizon tal moving walkways are increasingly used as well In 2015 Thyssen Krupp presented a high speed moving walk way whose pallets move slowly in the entrance and exit areas but reach a speed of 7 km h 4 3 miles in the central high speed area According to a study of the Swiss Federal Insti tute of Technology in Lausanne a speed of 15 km h 9 3 mph could be achieved by such a system Using real data from Geneva the researchers developed a mathematical model of a moving walkway with a network ex tending across a total of 32 kilometers 19 9 miles Transfer points would enable users to switch between the in dividual moving walkways According to the university s calculations such a system could be ten times as eff ective as private car transportation The impressive Elevador de Santa Justa connects Lisbon s Lower and Upper Town The Central Mid Levels escalator system traverses an elevation of 135 meters 443 feet from bottom to top on a distance of 800 meters 2 600 feet foreseeable consequences even though a subway tun nel to the other side of the city has also been available since 2013 Or you just take the good old ferry again Ac tually using inner city waterways for local public trans portation may well be a viable future option for instance in the form of autonomous electric ferries with short in terval sequencing and capacity utilization that can be optimized thanks to modern connectivity technologies In Paris SeaBubbles is the fi rst company to have tested electric water taxis on the Seine River and Tokyo Water Taxi is planning to direct a fleet of 60 boats by the time of the 2020 Olympics Conquering airspace the easy way Let s turn from the road and water to another traf fi c area While Uber Airbus company are pursuing the conquest of airspace using costly drones and air taxis that are hardly energy effi cient examples of how this can be achieved faster and at lower cost have existed for quite some time a stop in La Paz the hilly seat of Bolivia s government Here citizens have simply been taught to fly The Teleférico the world s largest urban cable car system with fi ve lines and a network length of 19 kilometers 11 8 miles is able to transport 125 000 people per day The advantage of such a system is that it hardly requires space and is comparatively easy and in expensive to build Medellín Caracas Ecatepec de Mo relos on the outskirts of Mexico City Ankara Berlin and other cities especially in Latin America are by now op erating aerial transportation systems African metropo lises such as Lagos Nigeria and Mombasa Kenya are thinking about adapting them In New York the East Riv er Skyway could connect North Brooklyn with Manhat tan similar to the cable car system to Roosevelt Island that began to operate in 1976 Canadian innovator Charles Bombardier has imag ined this concept even a few steps further His Urba nia proposal is an inner city chairlift with closed cabins traveling close to the ground By contrast his Panama idea takes its passengers to loft y heights traveling be tween skyscrapers in cabins suspended under a rail 95 outlook
