<p>Systems and methods for geographically based analyses of traffic being carried over a wide scale traffic network (10). The systems integrate (12) geographical information systems (GIS) with traffic simulation processes (18, 20) to allow a user to analyze traffic patterns and loads at specific geographic locations of regions. Additionally, these systems allow for traffic analysis over a wide scale traffic network that may encompass the traffic network that exists within an geographic region and can include, as examples, the traffic networks that span across a city, that interconnect cities, that interconnect states and that run across multiple states. To this end, the systems include traffic simulators that can adaptively or controllably select between multiple traffic simulation models for simulating traffic across different segments of the traffic network (18, 20). The different models provide varying levels of granularity for measurements of geographical location of a vehicle traveling over the traffic network. Thus, portions of the traffic network that are to be analyzed more closely can use the traffic simulator model with the highest degree of granularity, while traffic patterns across other areas of the network may be modeled with lower granularity models that may provide for computational efficiency.</p> |
