The Strategy – How Cities Manage Traffic


The PTV Group initiates the online survey “The Strategy – How Cities Manage Traffic”

It has to be commercially-viable, environmentally-friendly and socially sustainable. The long-term traffic planning efforts are considerable. But how do we translate a project into tangible action? Here, anyone would like to able to be a fly on the wall and take a look at what the neighbours’ strategy is. With ‘The Strategy – How Cities Manage Traffic’, the PTV Group is taking on the challenge and initiating a survey. With, interested persons can still participate up to 8 March 2014.

Moving away from the car towards the bike and public transport. The change to mobility behaviour is also reflected in transport planning. Instead of focusing on motorised private transport, cities and local authorities are keenly following a multi-modal approach today. In order to optimise driving speeds, to increase the capacities of the road network and to moderate the effects of traffic jams, different strategies are being implemented here: while some are concentrating on an improvement in traffic management, others are looking to build new traffic infrastructure, for example.

What are the actual requirements? Which measures are being taken to achieve the goal? And where are there regional differences? With the survey ‘The Strategy – How Cities Manage Traffic’, PTV Group would like to get to the bottom of these issues and has initiated an online survey. “As providers of transport planning software, it is exciting for us to see where the trends in the transport planning sector are heading,” says Paulo Humanes, Director Business Development at PTV Group. “This gives us important impetus for further development of our software.”

The first road fatality in the world



The first traffic accident has happened more than 115 years ago in United Kingdom. The first human to be victim of a through means of transport provoked accident was a 44-years old woman named Bridget Driscoll. The vehicle that has hit her belonged to an Anglo-French Motor Car Company.Read more

“Mount Klotz” quivers

More than 210,000 people conquered the Guenther-Klotz open air leisure complex on July 20 and had three days of great fun at the festival DAS FEST. Since 1985, the annual event, which is one of the largest open air festivals in Germany, has been an integral part of the entertainment programme of many residents of Karlsruhe. Not only numerous nationally and internationally known artists such as Deichkind, Culcha Candela or Bubble Beatz, but also PTV was involved in the event – with a new video.

The video is an animation created with our pedestrian simulation software PTV Viswalk explaining the process in the detached, front area of the main stage. Taking an active role in the development of this section, we had the chance to bring in our expertise in event planning, as last year. Another novelty was the application for smart phones (DAS Fest-App) by YellowMap AG, launched by the organizers. In addition to the festival program, the app also includes our simulation of entry and exit processes – as a result, each app user had the PTV Group on his or her mobile phone.

The mind of movement – the challenge

Our question of this week is dedicated to pedestrian simulation, or more precisely the Social Force Model which was inspired by Newton Dynamics and describes the interaction between pedestrians by mathematically formulating social and psychological impacts as forces. The question this time goes as follows:

Who was not involved in the development of the Social Force Model?

1. Prof. Dr. Dirk Helbing

2. Péter Molnár

3. Isaac Newton

Do you know the right answer? Go simply on, select the correct answer and send it to us. We wish you lots of fun and good luck in winning the challenge!

Background information and tips:

Motivation for movement
Pedestrians move purposefully as a rule, meaning they walk at a desired speed toward their destination and they want to reach it as quickly as possible. The quickest route is often very similar to the shortest route. However, there are situations where this “rule” does not apply – the simplest of which is when a large group of pedestrians is doing a u-turn, for example. The “detour”, i.e. the larger radius, is then expected to be the faster solution.

PTV Viswalk is a pedestrian simulation tool specifically designed for realistic modelling of pedestrian behaviour. The underlying function is called “dynamic potential”.

Urban jungle New York

Pedestrians crossing the road despite red light regardless of the traffic, cyclists using the opposite lane of the street and cars acting like they own the road being the “strongest” of all road users.

The New York traffic is rough and pretty much unhindered breaks almost all the rules of the road traffic regulations. One of the 12,370 crossings in New York has now been carefully observed by Ron Gabriel. The result is a video that demonstrates the daring maneuvers of car and bicycle riders and risky behaviour of pedestrians.


Background of the traffic monitoring: Ron Gabriel’s video recording is part of the “NYC Goes Three Ways” project to increase the safety on the streets of New York.

VISWALK: New features for escalators & moving walkways

VISSIM, VISWALK, simulation, terminal, escalator, pedestrians

The service pack 1 of VISSIM/VISWALK 5.40 also includes enhancements of the escalator/moving walkway feature:

  • Pedestrians can now walk on escalators/moving walkways. Along with the percentage of pedestrians walking you can also define the pedestrian classes affected.
  • For the location of the remaining (standing) pedestrians you can choose from left, right or random side.
  • You can select different display types for balustrade, handrail and socket.

We have a new video online showing escalators in a terminal simulation. You can also download it from our VISWALK AVIs section in a higher resolution.
