The methodology presented in this report produces many results at different stages of the calculation process. These results highlight patterns of accessibility by transportation mode, activity type and age group. The subtle differences in what is being calculated and at what stage should be kept in mind when interpreting the results.
Step 2 of the methodology produces a table of travel times between each location being tested and each instance of an activity. At this stage the result is simply travel time across the network in seconds.
Applying the (λ) parameters in step 3, converts these travel times into the percentage of people who would make the journey of the calculated length (from the measurement location to the activity). It is expressed as a decimal, eg 0.25 = 25%.
