Continuous reports

Continuous reports avoid the use of thresholds by using algorithms based on observed travel behaviour or other criteria to represent the separation between origins and destinations. The reports record the number or percentage of a population with access to a destination type, and weight the population closer to the destination higher than a population that is further away. The algorithms are often negative exponential or weighted logistic decay equations calibrated and fitted to observed behaviour from trip length distribution data. Or said another way, destinations that are further away from an origin are assigned lower weights reflecting the attraction of each destination, with remote destinations receiving less and less weight until they become insignificant to the overall measure of accessibility.
