VEDENS in Action
Using the model it is possible to carefully control parameters such as
driver and vehicle characteristics. It is also possible to investigate the effect
of various road configurations. Any experiment involving real drivers and vehicles
would be extremely expensive and time consuming. It would be impossible to control
driver reactions in a precise manner. The risk of accidents could, in some circumstances,
be much higher than for normal driving. Furthermore, the conditions which could
be investigated by the model may well be illegal. It would also be extremely inconvenient
and politically insensitive to close many tens of miles of motorway to carry out
carefully controlled experiments. In addition, by using the model it is possible
to investigate road configurations which do not exist at present.
