Välkommen till GTS Stiftelsens trafikblogg

- en nyskapande trafikblogg

Välkommen till vår trafikblogg! Vi tror att ett helt nytt, generellt transportsystem (GTS) behövs. Ett som kan tävla med våra gamla vägar och järnvägar. Ett sådant system skulle använda de bästa egenskaperna från bilen och kollektivtrafiken, men undvika deras nackdelar. Nya tekniska förutsättningar ska utnyttjas till fullo. Resor kan då utföras utan byten, tidtabeller, energislöseri, förbränningsavgaser, partikelutsläpp, P-bekymmer, tidsspillan, körkort, färdtjänst, förare, buller, dödsfall och personskador. Totalkostnaden skulle därtill troligen bli hälften medan hastigheten fördubblas! Transporternas kvalitativa utveckling har nu varit som förstenad i minst 100 år. Bilen är 100 år och järnvägen 200 år som uppfinningar. Jämför transporternas utveckling med IT-utvecklingen och biotekniken! Vi tycker att samhället formligen skriker - oartikulerat - efter avgörande innovationer på transportområdet – är vi tokiga?

GTS is a new way of thinking transportation

We have to break the box made out of habits, conventions and experience and all to often sealed with sturdy duct tape made of conviction, that limits our thinking regarding transportation. We have to take in the whole picture and not limit ourselves to piecemeal solutions of specific problems. We cannot continue to build systems that require hubs, where the hubs create the congestion that the systems are built to solve.
It is hard to “think out of the box.” In transportation it seems that people have their thinking locked into train boxes, bus boxes, car boxes, tram boxes and now also podcar boxes.
We think in terms of freight, cars and public transportation, as if they were separate issues. This leads nowhere, as the discussions only touch part of the total problem, which is not only about getting people to and from work or about getting goods from A to B, it is not only about energy efficiency or emissions. The problem is to find practical, technological solutions that fit the needs of modern society, the needs of people who try to keep their lives together, to find technologies that allow us to build a more sustainable society that is both more humane and more efficient.

Public transportation and rail services depend on concentration of people and goods to a limited number of hubs. To get from point A to point B, people have to go to a bus stop or a station, from where they are taken to a main hub, where they change to something that takes them to point B - or close to it. Often after changing at yet another hub.
Freight is transported to a central hub, sorted and then dispersed again in all directions.
If you live or work close to a main hub, or have your business close to a freight hub, life is easier. The hubs are a major cause of congestion. Expansion of public transportation or rail services thus contribute to the very congestion that the investments aim to ease.
Roads, with cars and trucks, work differently. Cars and trucks can go the shortest or fastest way, directly from A to B. This makes them very attractive for travel and freight, in spite of their drawbacks: accidents, pollution, their excessive use of valuable space, high energy consumption, and demanding skilled drivers.

Podcars, commuter trains and buses, subways and other modes of public transportation only address one particular transportation need. If one takes a look at causes of the difficult traffic situation in major cities, it quickly becomes evident that it is not enough to solve only the commuter problem. In a city like i.e. New York, with high population density and high buildings, a major part of the limited parking spaces are occupied by delivery and service vehicles. They clog the streets even though a high percentage of New Yorkers walk or ride the buses and subways.
It is in a way not correct to make a presentation of GTS at a podcar conference, because GTS goes way beyond podcars. As the name, General Transportation System, implies – GTS can solve all transportation needs within a modern metropolis area, except the needs for heavy construction.
GTS differs from all other transportation technologies, both existing modes of transportation and proposed, by taking in the whole spectrum of transportation needs. Like roads, the GTS system can take on all kinds of loads. It can move small vehicles for individual travellers, bigger vehicles that fill the same roll as buses or trains and cargo containers of different sizes and for different needs. And like roads, the GTS system can load and/or unload just about anywhere, and move both people and things the fastest way from A to B. The big difference is that the GTS system is automatic, thus requires no drivers, no driver’s licence, no navigation skills. It is also faster, safer, more energy efficient and less intrusive than roads. As it takes people and goods directly from A to B and is capable of high speeds with platooning of the vehicles, it can compete for total travel time with even the fastest trains, who only can take passengers from terminal to terminal or hub to hub.
GTS breaks the molds that until now have forced humanity to accommodate to the limitations of technology. With GTS technology it is possible to break the thinking box that makes us think in well established patterns when we think transportation.
But even the proponents of GTS find it difficult to break out of the thinking box. Words like “stations”, “terminals” and “stops” are frequent even in the descriptions of GTS and in the thinking around GTS.

These are words that should be banned from the GTS vocabulary, as they detract from one of the most important features of GTS: That it does not need terminals, hubs and designated stops. At least not the terminals, hubs or stops we associate with public transport of today.
A lot of effort has been put into designing ways to lower the GTS cabins to the ground, to allow passengers to embark and disembark at ground level. Less effort has been put into developing ways to connect the GTS system directly to the buildings, just as the roads are connected, but on the second, third or higher floors, how to move the containers seamlessly from the GTS track to the elevators and other transportation devices in buildings. And where space allows, the track itself can be lowered to the ground level to facilitate easy loading and unloading.
The GTS system, which is quiet and emission free, can be run through buildings, which allows for a completely new mindset when thinking of transportation. People could even commute in their office module, which can be moved automatically from their workplace to their home and back, turning commuter time into productive work time.

Freight can be divided into smaller batches that can be automatically transported from the goods terminals serving big cities, into stores and offices. It would even be possible to stock store shelves in the freight terminals and take them by GTS directly into the stores.
GTS allows for both individual transportation and large scale public transportation in the same automated system. The automation, the emission free and silent operation, allows the system to run at all hours without disturbance to the environment. In the daytime most of the capacity can be used for passengers, while at night most of the capacity can be used for goods. This dual use makes GTS more economical than systems that are dedicated to very specific transportation needs. GTS can also be used for dual mode transportation. Self-propelled vehicles can be driven like cars to and from the GTS system, and either be hung connected directly to the GTS vehicles with a GTS standard coupling, or driven onto a platform “pod”.

GTS can accommodate private or specialized vehicles that are automatically parked in designated facilities, and it can run standard vehicles that circulate on the beams until called upon by customers. Extra pods, pods for specific uses and extra capacity vehicles can be stored in strategically placed facilities, making it easy to adapt the GTS system to varying needs of capacity and or specialized pods.
GTS can provide a base for the development of new technology and new business models for transportation in the same way that the internet paved the way for new thinking in information exchange and computation. It can facilitate a new way to build our societies, where all locations can be equally efficient, with equally fast door-to-door transportation between all points within a region.
The GTS is not a fixed system. It is a system that can grow and be transformed with evolving coverage and evolving needs. It can be an internal conveyor system in a warehouse, and it can be a regional transportation system that makes car traffic and distribution trucks obsolete – freeing up the roads and streets and eliminating traffic accidents. And it can be everything in between. It can supplement the present modes of transportation, and provide those first and final legs of a journey, between the As and Bs and the terminals, where large scale transportation systems cannot go. GTS can cooperate and GTS can compete.

There are no set business models for GTS systems. The standards of the system allows for a wide range of companies and public agencies to build and operate GTS systems or fleets of vehicles. Pods can be individual or public, privately owned or operated by companies or public agencies.
GTS provides endless possibilities. The only limitation is the box that limits our imagination of future transportation systems and technologies.
We have to break that box!
