Bing Maps MIO API update
Blog|6 May 2020

Microsoft is helping companies respond to the sudden increase in demand for delivery services, with its Bing Maps Multi-Itinerary Optimization (MIO) API.
To meet the need for effective multi-stop route planning for delivery drivers, Microsoft has expanded the Bing Maps MIO API features to now support up to 200 agents and 2000 itinerary locations (versus the recent update of 50 agents and 500 itinerary locations).
Its AI capabilities make it possible for despatch operations to schedule itineraries for multiple agents (eg., drivers, field service agents) and multiple shifts, while also optimising the routes among all agents to save travel time and distance.
A summary of the updated features, since launch, are below:
Features supported at Launch
– Multi-day route planning
– Multiple agents and multiple shifts
– Service time windows
– Priority of stops
– Dwell time
– Predicted traffic
New Features added since Launch
– Vehicle capacity
– Quantity to be picked up or dropped off at each itinerary location
– Pick up and drop off location sequencing dependencies
– Depot location which can be visited multiple times to pick up loads as needed
An example of MIO API for a home delivery service
A home delivery service – picking up orders from the warehouse and delivering to customers during different time slots – requires complicated scheduling that takes into consideration delivery locations, delivery time windows, and multiple visits to the warehouse for reloading.
This scenario makes use of the capacity
, quantity
, and depot
parameter options. A delivery driver “John” needs to pick up some large objects like home appliances and furniture from a warehouse and have them delivered to customers at different locations. Each customer has a specified time window for delivery.
If the delivery quantity
is large and exceeds the capacity
of the agent’s vehicle, the agent needs to be able to make multiple trips during the day to reload at the “Warehouse” and deliver all goods. In the MIO API request, the “Warehouse” can be defined as depot to allow the location to be visited more than once. In this example, quantity
can be used to represent the volume in square meters.

The table below summarises the optimised itinerary for driver_John for the above itinerary items.

The itinerary for driver_John is illustrated on the map below. With a capacity constraint of 16, driver_John needs to return to the “Warehouse” several times to pick up more quantity to fulfil the delivery requests from all the customers with a total quantity of 35.
On the map, Location 1 denotes where driver_John starts his shift. Location 2, Location 8 and Location 10 all overlap with Location 1, as the driver needs to load several times from the “Warehouse.” By setting “depot”: true in the JSON request, the API allows the truck to visit an itinerary location more than once.
