Abstract

The driving models on behavioural basis could do better understand as any variations of the environment perception influence the performances of driver-vehicle system; or, just by the model functioning, it is possible highlight a lack of experimental data. Again, a working correctly model could be part of a more complex microsimulation system that uses results. The suggested model results from experimentation of drivers behaviour in defi-nite flow conditions and considers the vehicle dynamics and the driver reactions as stimuli caused by interaction with other vehicles. The model consider the flow conditions on two lanes roundabout with possibility of exchange through lanes. The lane change could happen from right to left or vice versa. The experimental investigations have allowed the evaluation of some functional relationships between used motion parameters. Another relationships, now, have been only suppose with congruent variations of the parameters. In this way the suggested model doesn't lose his validity and could be considered open: it will be improved when new and more accurate experimentations will be available. Object of this work is obtain a driving model that doesn't reply entirely to the logic of the car following (for an only lane) but allow the vehicle control also when an other vehicle, from an adjacent lane, try or effect a change on the his running lane. Similar flow conditions are verified, for example, on highway, on rural roads with more running lanes, on the urban flows and on the roundabout intersections. The motivations for lane change are substantially similar: for the countries with circulation to right the lane change in left direction is definite for keep a running speed higher than those al-lowed on the own lane; the lane change to right, instead, could be motivated or by the opportunity of reenter in normal running lane, after have effected an overtaking, or by the need to go out, after, of flow. For study the shown manoeuvrings has been realized a first survey on three dif-ferent intersections with similar geometric characteristics, with different circulation conditions (variable flows) and with different drivers customs (the roundabouts intersections are in two regions). The data acquisition, extraction and next analysis have furnished necessary indications to define a first simplex behavioural models.
