Traffic Micro-simulator

The road infrastructure is modeled into the computer and data from counting originates the load of vehicles traveling on it. Each vehicle is modeled individually, and statistical techniques are applied in the model calibration and validation.
The drivers’ behavior is described by probability distributions, recreating the heterogeneity that can be observed in reality. The interaction between vehicles is obtained by applying algorithms of car-following, lane-changing, and gap acceptance.
The model is represented in a three-dimensional virtual scenario. The traffic data obtained from the simulation are presented in maps, charts, and tables.
Through the construction of alternative infrastructure models it is possible to evaluate each situation in the virtual scenario and identify the best alternative in terms of traffic flows before the execution of projects.
Some micro-simulation traffic application areas are:

• studies of urban road systems;
• studies of public transportation corridors;
• studies of port and terminal accesses;
• studies of level crossing and intersections.

Hypothetical example of application

This is a set of three videos with the sole purpose of demonstrating the potential of the micro-simulation technology for traffic studies and projects.

• Demo Video 1 (a hypothetical scenario): Current status of demand and infrastructure (calibration).
• Demo Video 2 (hypothetical scenario 2): Projected demand (for 2025) and current status of infrastructure.
• Demo Video 3 (hypothetical scenario 3): Projected demand (for 2025) and the hypothetical situation with infrastructure modifications.
