Travel Time Savings
Cost Savings

3. WHAT IS ACCESSIBILITY?
 In urban transportation, ‘accessibility’ refers to the ease
with which an individual can access opportunities (e.g.
employment, health or education services), given the
spatial distribution of the city (land use), the transportation
infrastructure and services available (transportation
supply), the temporal constraints of individuals and
activities, and the individual characteristics of people.

4. ACCESSIBILITY

5. ACCESSIBILITY TOOL
 A planning tool to quantitatively assess urban accessibility
 Works on OpenTripPlanner software and its extension ‘Analyst’
 This tool leverages digital, open, and standardized data
 Road Network: OpenStreetMap
 Transit Network: General Transit Feed Specification (GTFS)
 Population
 Opportunities: Jobs, schools, health centers, parks
 The tool then combines the estimated travel times for each of the chosen travel
modes and location data for employment opportunities (or parameters) to calculate
the accessibility value for every point in the city for a given time threshold. 5

6. WHY USE THIS TOOL?
1. Global and Local Tracking Framework
 Planning Indicators
 Benchmarking
 Sustainable Development Goals
2. Transport and Land Use Planning
 Quick and simple modeling tool
 Move towards a data-driven and evidence-based planning
3. Investment Prioritization

7. IMPROVING PLANNING
 For example, you can estimate accessibility to:
 Employment Opportunities
 Schools, Education Centers
 Health Centers
 Entertainment Centers and Green Areas
 Shopping Centers
 As well as the accessibility under different transportation scenarios, for
example:
 Route reorganization
 New infrastructure
 Different levels of service and operations

8. DATA SETS
 Transit data:
 Bus routes (on Google Earth/GIS/AutoCAD)
 Bus stops (on Google Earth/GIS/AutoCAD)
 Bus schedules / GPS logs
 Other data:
 Recent population (blockwise/ward wise)
 Jobs (office locations with total employees)
 Schools, hospitals, … (locations with total strength)

22. Moving Forward
 Tool Improvements
 Affordability: Adding double thresholds for time
and cost of travel
 Quality
 Scale up
 Improving data
 Global Metrics
 Wide-spread utilization as a local
planning tool

23. LIMITATIONS OF THE TOOL
 The tool has certain limits for visualization such as it doesn’t allow modification of colour coding, ranges
etc in the tool as it’s a web based interface. However the data can be downloaded so that the
modifications can be made in a local PC
 Tool requires high bandwidth for functioning as the site is developed based on server side processing
(even though they are placed in clusters)
 Comparisons for more than two scenarios can’t be done in the tool
 User side tweaking of traffic parameters are not possible in the tool and they have to be modified only
with the initial GTFS creation
 The tool is not designed for creating optimal scenarios but it rather evaluates and compares them
