Method for modeling an urban area including a road network

Abstract

Method for modeling an urban area including a road network. Method for modeling a mapped urban area (1) comprising geographic portions (11), each geographic portion (11) being associated with at least one environmental factor, the method being characterized in that it comprises the following steps: A data collection step (E01); A data aggregation step (E02) in a database (140); An analysis step (E03) to verify the conformity of at least one environmental factor with a predefined criterion; If the environmental factor is compliant, a strategy development step (E041) to maintain the conformity of the environmental factor; If the environmental factor is non-compliant, an evaluation step (E042) of strategies to make said environmental factor compliant, then, A strategy selection step (E05); A step of transmitting instructions (E06).

6. A method according to the preceding claim, characterized in that when an environmental factor level is greater than or equal to the second threshold value, the analysis step (E03) includes a prediction substep (E035) over a time horizon of the evolution of at least one environmental factor for at least one geographical portion (11).

7. A method according to any one of the preceding claims, characterized in that the development step (E041) of different strategies and the evaluation step (E042) of different strategies each include at least one sub-step of simulating (E043) the consequences generated by the application of each evaluated strategy.

8. Method according to the preceding claim, characterized in that it comprises a recording step (E044) in a database (140) of the results obtained following at least one simulation substep (E043) and a comparison step (E045) of said results.

9. Modeling system (100) of a mapped urban area (1) comprising a road network (10), the modeling system (100) comprising a representation module (110) configured to represent the road network (10) of the urban area from data collected by environmental perception means (25), at least one communication means (120) configured to exchange with the environmental perception means (25) and with users (20) and a decision-making module (130), the modeling system comprising hardware and / or software elements (110, 120, 130) configured to implement the method according to any one of the preceding claims.
