Background & Insights
STRATEGY AND CONSIDERATIONS
OSM: OSM base map and OSRM was used for the routing
Routing: EOC serves as the start point, routing was based on proximity and FIFO, which is
used to determine cluster and drops for a particular date within a time zone (9am-11am,11am-
1pm,1pm-3pm) . Batch Routing by Nicholas.
Historical Data: There are no historical data on roads hence the travel time was pegged at
60km/h to count for traffic jam, bad roads, check points, rain, etc.
Cascade maps: This are maps that shows parent and child facilities, service & coverage
areas, supply method and frequency.
Driver’s Training: Drivers were trained on usage of mobile apps for routing and data
collection. (osmand, GPS Essentials, My tracks, Google Maps)

Cascade Mapping

Analysis of the Cascade Network in practice• 80% of DDF are informal stores to CF, a third of which are in wards other than their own
• 32% of CF lie in wards other than their DDF Parent’s ward
• 90% of CF fall beyond a 2km radial service zone of its parent and 70% fall beyond a 4km radial delivery zone

• OSM: OSM base map and OSRM was used for the routing
• Scheduling: EOC serves as the start point, routing was based on proximity and FIFO, which is used to determine
cluster and drops for a particular date within a time zone (9am-11am,11am-1pm,1pm-3pm) to be delivered by a driver.
• Routing: It is based on proximity of health facilities to each other using road network
• Historical Data: There are no historical data on roads hence the travel time was pegged at 60km/h to count for traffic
jam, bad roads, check points, rain, etc.
• Cascade maps: This are maps that shows parent and child facilities, service & coverage areas, supply method and

• Drivers Training: Drivers were trained on use of mobile apps for routing and data collection. (osmand, GPS Essentials,
