Resumen

Pedestrian behavior can be studied force through the social model, which represents the behavior of people through attraction forces that describes the interaction of pedestrians with the environment. These interactions determine the variation of the pedestrian's trajectory, speed, and acceleration. Present investigation seeks to formulate a model of microsimulation software in the Vissim / Viswalk considering pedestrian behavior. The classification of pedestrians' age range is essential for the investigation since it allows to model a behavior closer to reality considering travel speed and trajectory. Results show that tau and social lambda variable force were reduced by 84% and 15% respectively. Also, the travel speed of pedestrians concerning the field data without considering the classification exhibited a pedestrian realism of 84% and 88% and considering the classification by age range are 97% the realism. Finally, when considering the psychophysical behavior of pedestrians in the simulation model an increase up to 17% in the calculation of delay of a road monitoring system is evidenced.
