What are the different types of traffic
New types of mobility #
Introduction#When one speaks of mobility, it must first be clarified what type of mobility is meant: mobility is usually understood to mean spatial mobility. But there are many types of movement / agility - mental, social, cultural ...

While the last forms of mobility undoubtedly have a positive connotation, this has not been unreservedly true for spatial mobility for some time: for too long, traveling faster and cheaper for people and goods has been synonymous with progress.
In the meantime, the downsides of unrestricted spatial mobility, traffic, in the form of enormous resource consumption and emissions problems including climate change, effects on health, but also through the increasing spatial-functional differentiation are becoming clearer.
The increasingly clear drifting apart of places of residence / work / leisure and purchase requires an increasing willingness to be mobile and, consequently, the actual movement between the different destinations. Mobility gradually turns out not to be an increasing freedom of choice for the individual, but something inevitable.
This is accompanied by a clear / dramatic decline in easily accessible infrastructure (local suppliers, medical care, public and financial services, etc.), which makes mobility a particular problem for individual population groups and also makes mobility a social one.
Mobility has lost its nimbus as a motor for progress per se and all lines of development for improvement must be analyzed in a differentiated manner, especially with regard to the effects.
Sustainable mobility? #From today's point of view, new types of mobility appear compatible with sustainable development, which are subsumed under the term "soft mobility", which includes the so-called "environmental network" (public transport (public transport for short), cycling, walking) .
First of all, the understanding that mobility is equated with the availability of a car must also be dispelled. For a long time, mobility has developed along with the increasing use of cars. However, mobility basically simply means the spatial mobility of people and goods - and this is covered by different forms.
In the first, comprehensive survey of mobility in Austria for decades, which was carried out from October 2013 to October 2014, essential data on the types of spatial movement were determined in a Europe-wide standardized procedure .
It can thus be stated that:
- 83% of people are mobile on a working day
- an average of 36 km are covered, which takes 70 minutes,
- 46.8% of the journeys as a driver of a car (on Sundays only 37.8%), 11.8% as a passenger in a car, 17.5% of the journeys on foot, 16.6% with public transport and 6.6% be covered by bike.
This means that today, on average, almost 60% of all trips in Austria are made by car.
The regional differences are enormous: in Vienna 24.6% of the journeys are made on foot and 38.8% by public transport. Compared to 1995, the proportion of public transport and cycling have increased slightly, while the use of cars has increased enormously - and the proportion of journeys made on foot has fallen by almost 10%.
Today, what is new in the way of transportation is not a technical innovation, but the challenge of changing this modal split - the division of mobility between different carriers - in a sustainable way. The carriers remain the same as before: MIV (motorized individual transport), public transport, cycling, walking. However, there are significant innovations that are intended to help achieve an ecologically and socially better way of coping with mobility needs.
Innovations #The primary goal in improving forms of mobility is to strengthen public transport. Public transport offers the best efficiency of all means of transport . Great efforts are being made to strengthen the share of public transport in the modal split:
- In terms of tariffs (e.g. the € 365 annual network card for Vienna, which has tripled public transport use); You start with mobility offers that simply combine the use of public transport with access to rental bikes, rental cars and, if necessary, taxi services.
- By improving the quality of the public transport network, but also of the stations and of the rolling stock.
- Through information services that provide passengers with exact data on their relations in real time using the new web-based media.
- Beyond the city centers, international S-Bahn trains or "regional trams" are being promoted, which serve shorter distances between stops than long-distance trains, but are also geared towards taking bicycles with you, for example (see multimodality).
Even smaller cities are now investing in urban railways, such as Gmunden with the city-regional tram .
However, for acceptance it is essential to link the public transport network with other mobility providers in order to meet individual mobility requirements. The goal is called "multimodal transport offer".
Large public transport hubs (train stations, bus terminals, etc.) are used as destinations for efficient bicycle connections and large, safe and high-quality bicycle parking facilities are set up. That means: protection of the wheels against theft and rain; If necessary, supplemented by bike service facilities (pumps, machines with spare parts), lock boxes for storing bike helmets and cycling clothing.
These nodes will be equipped with car and bike sharing services and - as in the past - with bus terminals. The connection of train and bus arrival and departure times should be well coordinated in order to keep waiting times short. In Mödling, a large display board was installed at the bus terminal in a pilot test to show the construction drivers any delays in rail operations. Buses wait up to 5 minutes for late trains to depart.
A novelty in supra-local bicycle traffic is the orientation towards cycle superhighways - also beyond the city limits and the integration of the surrounding area of the big cities in an efficient cycle network. The massive increase in the use of eBikes offers a practical perspective for many commuters to get to their distant workplace by (e) bike.
But in addition to the construction of new (kind) bike paths, there are also pioneering technological developments in the field of bicycles themselves: Since March 2017, the City of Vienna has been massively promoting the purchase of cargo bikes. Bicycles can now - possibly with electrical support - also take on functions in mobility that were previously reserved for car traffic, namely transporting loads and driving with (small) children.
In recent years, the principle of densification in large cities, but increasingly also in smaller cities, has become increasingly popular in spatial planning to improve mobility requirements: a densely populated residential area can be developed relatively easily with public transport. And in fact, car use is falling - slowly - in metropolitan areas.
Framework conditions and first results #It is important, however, that the conditions for walking (and cycling) are adequately offered in these metropolitan areas: people prefer to take longer journeys if they do not have to climb between parked cars.
Convenience restrictions of motorized individual transport - at least in the cities, through restricted zones reserved for pedestrian / bicycle traffic and public transport: these have been the pedestrian zones since the 1970s, but so-called "superblocks" can also do so, as in some cities be in Spain, where several streets are combined into blocks, with car traffic only allowed on the outer edges of these blocks - unhindered. Within the blocks, paths and recreational areas for pedestrians and cyclists will be optimized and streets will be rebuilt.
Groningen (NL) has divided the city center into 4 zones, each of which can be reached from the outside by car - however, there is no possibility of driving directly from one of the zones to another.
Ultimately, parking space management also controls mobility in cities, and was not just the so-called "stationary traffic". Some cities collect city tolls for entering the centers in order to limit journeys to at least the really important ones. In all of these cities, pollution has decreased significantly (Stockholm: 13% less NOx, 8% less CO2, 3% less particulate matter).
Nevertheless, individual mobility will keep a place in the mobility mix. However, in order to at least increase the pressure on the space requirements in stationary traffic and also the utilization of the vehicles used, car sharing is increasingly becoming a new type of mobility. Both in the conventional way with fixed parking spaces and in the form of free-floating (e.g. car2go from Daimler and Europ-Car).
The free-floating systems will be viewed with a bit of skepticism by traffic planners, as they compete to a large extent with public transport. But if cars continue to be used, then this form of transport should in any case cause less environmental pollution: that is one of the main reasons for promoting electromobility.
Competition of ideas #
Years ago, a much-noticed experiment with eTaxis took place in Tokyo, the battery of which was exchanged in seconds at special "filling stations". The project was run by a Danish-Israeli consortium “better place” and the solution was really impressive. Unfortunately, this project has not progressed for the time being and the company is now bankrupt.
However, there are also developments that are suitable for reducing the need for mobility - even if they are perhaps not initiated with this purpose:
Due to the better technical possibilities, companies are increasingly switching to organizing video conferences and thus reducing business trips. 6 years ago, Telekom Austria saved 2,000 business trips per year by promoting teleconferences, thereby saving around 150 tons of CO2. Even more important, especially for the daily commuter flows, is the increased use of teleworking in many companies in the service sector: employees work at least temporarily on their PC at home, which is - securely - connected to the company network.
These are all steps in the right direction: to make spatial mobility more sustainable, socially and ecologically compatible again.
 Study “Austria on the move 2013/2014”, published by the BMVIT in June 2016: http://www.oesterreich-unterwegs.at
 The VCÖ - Verkehrsclub Österreich has calculated in a study “Urban Transport of the Future” 1/2016 that the space requirement measured in area hours per person per day, which is 1 m² / h for a pedestrian, in trams and Bus at 40% occupancy is around 3.1 or 3.6 m² / h, while cycling is already 24.6 m² / h and with a car with 1 person is 371.3 m² / h.
