A regional Smart Para-Transit system would have many operational elements. Dealing with all such details is far beyond the scope of this article, but I will touch upon some of the key operational issues. One of the biggest issues for such a system would be parking for the vehicles. However, space for these vehicles is available. Since one Para-Transit van can replace 5 private cars, only a moderate fraction of the existing space dedicated to private cars would be necessary for the Para-Transit fleet. The region is filled with parking lots and garages that are empty at night. Repurposing only a moderate fraction of these spaces would solve the parking issues of storing the fleet.

Here is part four of Mark Gorton's essay, "Smart Para-Transit: A New Vision for Urban Transportation."

The Smart Para-Transit system I have described would be capable of replacing many of the automobile trips in the New York area. However, by itself, it would be insufficient to completely replace the need to own a car for many New Yorkers. If Smart Para-Transit were paired with a car sharing program, most all driving scenarios would be covered, and this system would eliminate the need for car ownership for all but the most driving-intense New Yorkers. Zipcar is an example of a private car sharing service.

The interface between the car sharing system and the customer would be the same as with the Smart Para-Transit system. The user would simply go to a website or a cell phone and enter what sort of vehicle they would like and the length of time they need the vehicle. The user would then be told the location of a nearby vehicle that meets their needs. A premium service that drops the car at the customer’s door could even be provided at an extra cost.

The biggest constraints on the transportation capacity of New York City’s road networks are the bridges and tunnels. The river crossings are jammed with traffic for a good fraction of each day. The only way to get more throughput capacity out of New York’s existing bridges and tunnels is to use them more efficiently. A vehicle carrying multiple people is more spatially efficient than a single passenger car, so by having HOV lanes, our existing bridges and tunnels can move more people at no extra cost. The Lincoln Tunnel already employs dedicated bus lanes, and this concept can be expanded.

Smart Para-Transit all by itself could provide good transit options but would not have trip times superior to a private car. However, if the Para-Transit buses and vans had access to HOV lanes at the river crossings and other constraints in the road network, the Para-Transit system could provide trip times superior to the private car. The Para-Transit buses and vans could zip through the bridges and tunnels while the private cars sat stuck in traffic. With quality vehicles, faster trip times, and cost savings, many people in the New York region would happily switch from private automobiles to Smart Para-Transit.

Here is the second installment of Streetsblog publisher and LimeWire founder Mark Gorton's essay, "Smart Para-Transit: A New Vision for Urban Transportation." Part 1 is here and you can also download the complete pamphlet.

Advances in information and communications technology offer the possibility of optimizing the performance of our existing road network in ways that were not possible even ten years ago. The ubiquity of web-enabled cell phones has put a mobile data input device into the hands of the vast majority of citizens. By applying cell phone, internet, and computer technologies, New York now has the opportunity to create a system which can vastly speed travel times, increase the throughput of our road network, carry more people, while at the same time, radically reducing the number of vehicles on the road, gasoline usage, CO2 emissions, congestion, traffic, and the harm that traffic inflicts on our neighborhoods.

A new form of mass transit can be created that offers trip times highly competitive with the private automobile to nearly all points in the region. This new form of mass transit takes advantage of the existing road network and requires very little in the way of capital investment. This new form of transit is Smart Para-Transit.

Background

The past 100 years have seen New York City and the rest of the country spend huge amounts of money on road infrastructure improvements to serve automobiles. With the advantage of hindsight, neglecting investment in mass transit while promoting automobile usage may have been a poor policy decision; however, highways, bridges, tunnels, and roads have been built, and New York must now maximize the value it receives from the hundreds of billions of dollars spent on its surface transportation infrastructure.

Although cars have been a significant presence in our world for as long as anyone can remember, from a historical perspective, the automobile is still a relatively new invention. The first 100 years of our society’s infatuation with the automobile was spent without bothering to answer the key question: "Can we fit all the cars we need to move around?" Congestion and traffic jams are a way of life in New York. The previous answer to congestion was to build more roads, bridges, and tunnels; however, the added road capacity only encouraged more driving and led to even more congestion. Our society now knows that it is impossible to build its way out of its congestion problems.

This is the first article in a five-part series by Streetsblog publisher and LimeWire founder Mark Gorton:

Traffic is a crushing problem that oppresses our city, yet many people who drive into New York each day do not have a good alternative.

I'm an engineer by training and the traffic flow problems facing large cities today have many similarities to the engineering issues that I have encountered at LimeWire, the peer-to-peer file-sharing service that I founded. LimeWire involves many computers connected to each other passing messages around a network. Early in the development of LimeWire, the network was choking on its message traffic as each computer tried to send more messages than the network could collectively handle. The solution to this problem involved having each computer reduce its message traffic and organizing the network to take advantage of efficiencies that could be gained by designing a new computer network architecture.

From a network management point of view, the road networks of New York and many other large cities are horribly engineered. The traditional traffic engineering solution to congestion problems is to try to increase capacity. However, similar problems in computer engineering are solved by reducing the underlying need for traffic. Biological systems, which are the most sophisticated systems on the planet, are extremely judicious in how they move things around.

Our surface transportation system today is premised upon the primacy of the private automobile, yet the private automobile is the single most inefficient means of moving people in a city. By catering to the private automobile, we have inadvertently made an engineering choice that maximizes danger, noise, pollution, and congestion and creates a host of other problems that suck the life out of our public spaces.

In less than ten years, with minimal capital expenditures, we can create a new form of mass transit that transforms the way we run our surface transportation system and drastically reduces the need to have private cars in New York City. I call this new form of mass transit Smart Para-Transit. Smart Para-Transit takes advantage of innovations in information and communication technology to create breathtaking increases in efficiency of our road network. My very rough initial estimate is that widespread adoption of Smart Para-Transit would allow for an 80 percent reduction in automobile traffic in New York City.

The basket of ideas involved in Smart Para-Transit are too long for one blog post. So I am serializing the explanation over the course of a week. For those of you who can’t wait, you can download and read the full description.
