Process of Accessibility AnalysisConcept Formation•Define the purpose of eth analysis and its context•Select an accessibility measure•Specify the accessibility measure
•Type of spatial unit•Origins and destinations•Attractiveness•Travel mode•Travel impedance•Parameters of the measure
•Identify data requirements
Data Preparation•Data Collection•Input data pre-processing
Computing an Accessibility Measure•Calculate travel impedance•Identify destination sets for each reference location•Calculate the accessibility measure
Interpretation and Evaluation•Present the accessibility measurement results•Interpret and evaluate the results
