1. A system for determining a microenvironment, the system comprising:

  • a first plurality of monitoring devices located in a first vehicle, each of the first plurality of monitoring devices configured to monitor at least one condition among a plurality of vehicle conditions of the first vehicle, the conditions including a vehicle location and a vehicle speed;

    a first terminal coupled to the first vehicle and configured to collect a first set of condition information related to the plurality of conditions of the first vehicle;

    a first communication device connected to the first terminal and configured to transmit the first set of condition information through a wide area network;

    a second plurality of monitoring devices located in a second vehicle, each of the second plurality of monitoring devices configured to monitor at least one condition among a plurality of vehicle conditions of the second vehicle;

    a second terminal coupled to the wide area network and configured to receive the first set of condition information and a second set of condition information, the second terminal further configured toarrange the first set of condition information and the second set of condition information based on a set of microareas, each microarea including a two-dimensional area defined by a set of geographical coordinates,use the first and second sets of condition information to create a set of microarea condition information for a first microarea,evaluate a correlation function related to at least one respective condition in the set of microarea condition information to determine a first set of microenvironment conditions for the first microarea,determine a validity of the first set of microenvironment conditions based on a comparison of the first set of microenvironment conditions with a second set of microenvironment conditions from a microarea that is adjacent to the first microarea, andanalyze the first set of microenvironment conditions for the first microarea, at least a second set of microenvironment conditions from at least one microarea adjacent to the first microarea, and a previous set of microenvironment conditions of the first microarea to generate a first microenvironment condition report and a future microenvironment condition report; and

    a second communication device coupled to the second terminal and configured to pass the first microenvironment condition report to a plurality of users.
