The next major change for the idea of “streets” came with the invention of the railroad. This new “metal street” allowed for much grander distances to be traveled and as a result also greatly increased the interaction of more people, from even more diverse cultural backgrounds. Then came the automobile, which as it became more technologically advanced, demanded more and more specialized infrastructure. As the popularity and amount of use of automobiles grew, the streets of the city changed to accommodate.
Now the actual street no longer allowed for exchange and interaction, these activities were relegated to the edge of the space where the sidewalks and storefronts reigned. This relationship of fast and slow travel had always existed, but never had it been so exaggerated. This disparity of speed required a segregation of space in order to ensure safety for the slower pedestrian traffic. The rate of speed and limited occupancy of automobiles also negated the opportunity for interaction between them, limiting contact to only a prescribed series of flashing lights, beeps, and assorted hand signals. Even interaction from eye contact became limited to residential districts because of the sheer amount of prscriptive signage.
But vehicular streets of this scale still allowed opportunities for interaction at its edges. Even when these streets grew into highways, there was an opportunity to interact with towns as one slowed down when passing through. This allowed the driver to see the town, and perhaps even stop to sample local goods or services. So, there was visual interaction (albeit one-way) that led to the opportunity for further two-way interaction. This is how the highway still managed to be a place.
After the highway came the Interstate. Earlier we called the Interstate a “nonplace,” the reason for this is that instead of interacting with cities (like the highway), the Interstate instead circumvents the city or divides it into sides or parcels. Where the highway coexists with a city, the Interstate excludes itself, and by doing so removes nearly all opportunity for interaction. The only areas that interaction is allowed at are on and off ramps, and even this interaction is limited to whatever destination is determined by the driver (and this decision is largely based upon more prescriptive signage. As such the Interstate has failed to become a “place,” it is instead a void, a lack of place, which is only useful for traversing between predetermined places.
This is where the Internet can come into the conversation. While air travel is related to this discussion, it also largely follows, or in some cases, replaces the train. Airports and train stations both act as cultural and transportation hubs, and both involve large groups of people at a time. Also, both require down periods between travel events, thus creating huge opportunities for exchange, and the same goes for subway and light-rail systems. The act of waiting and traveling in mass are exactly what allows these places to act as public space, and what keeps the Interstate from doing so. The Internet is related to these places in that it too requires multiplicity and user interaction.
