In recent years, the term “Smart Cities” has become popular in Europe and abroad. There are various definitions of the term, but none of them are generally accepted. Smart Cities seek to optimize their systems by increasing integration through approaches such as increased interoperability, seamless system integration, and automation. Thus, they hav...
Nowadays, urban road tunnels are considered to be independent entities within a city. Their interactions with the rest of the city and vice versa are usually not considered and, if they are, are only considered in a limited way (for example, through the nearest traffic controller). Typically, only the traffic parameters and not the environmental im...
The traditional transport models such as the well-known four-step model have certain limitations especially with respect to modelling changes in travel behaviour due to certain policies.

Question (1)
Hi, I am working on a calibration of an AIMSUN model (V7.0) for a highway segment. i am having a problem to calibrate the model in a way to keep the behavior of the vehicles realistic and at the same time reach a break down in the fundamental diagram, i.e. instability. The problem is in creation of shock waves. Do you have any experiences on how to set parameters of the Gipps car following model to achieve that? Thank you,
