Systems and methods are disclosed herein for aggregating event data in order to reduce the amount of storage space necessary to store event data for later use in statistical analyses of the event data. The raw event data is analyzed and, for each event ID within a time period, a specific set of numbers and sums are calculated. This set is then stored instead of the raw event ID and used for all subsequent analyses of the events. The set of numbers and sums reduce the amount of storage required for each event ID within a time period to a set of five data elements, regardless of the number of underlying events in the raw event data. The set of number and sums include a number of events, a sum of the events, a sum of the squares of the events, a sum of the cubes of the events and a sum of the events raised to the fourth power.

Methods, systems, and apparatuses for determining parking availability are described. A sensor system is configured to monitor a plurality of parking spaces. The sensor system includes at least one sensor element that generates a sensor data output signal. A parking availability determiner receives the sensor data output signal and generates parking availability information. The parking availability determiner is configured to determine from the received sensor data output signal at least one parking space of the plurality of parking spaces that is occupied, and to include an indication in the parking availability information that the determined at least one parking space is occupied. If one or more further parking space are included in the plurality of parking spaces other than the determined at least one parking space, an indication is included in the parking availability information that the further parking spaces are available for parking.
