In this paper, the capability of microsimulation models for representing real-world traffic conditions, encountered in ‘chaotic traffic environments’ of developing countries, is analysed. For this exercise, two suites are used: VISSIM and DRACULA. A small scale network in La Paz city has been built as a case study. Then, an assessment of each model’s capability for modelling the following components is carried out: atypical junction geometry; high number of public transport vehicles; indiscriminate bus stops; aggressive driving behaviour; and lane indiscipline. From the analysis of the case study, conclusions are drawn out which highlight the main advantages and disadvantages of the microsimulation models for representing the ‘real world’ of less developed traffic environments.
