Process of Accessibility Analysis

• Concept 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
