About HERE Tour Planning Tour Planning is a REST API that is responsible for multi-vehicle route optimization. It provides a way to solve variations of the Vehicle Routing Problem (VRP). Customers can use it to plan their fleet of delivery or service vehicles while taking into account several constraints such as time windows, capacity, cost, maximum travel time/distance, driver breaks, etc. As a result, the API returns a cost-effective sequence (tours) to visit all the stops in the daily plan. Learn more about the product here: https://developer.here.com/products/tour-planning   About the team We are an international team of product developers that deeply care about building things the right way and bringing value to our customers.
