Capture-recapture techniques were used to estimate aspects of the populational dynamics of the convoy of vehicles parking at the Lavras-MG city center during the inter-term holiday period, from August 26 until September 24, 2002. We started from the open population model of Jolly-Seber. Generalized linear models were used (log-linear), according to Cormack (1989). Such models demand individual records and also its previous capture history. The vehicles plates were used as marks. No source of significative interaction was detected, and this suggests a geographically and demographically closed population. Point estimates values were next to the 6.000 vehicles, but the confidence regions were very broad. It was suggested that parsimonious models (closed population models) should be considered to get more accurate estimates.
