Markets play crucial role in ensuring food security as they serve as trading points in purchasing agricultural inputs and selling agricultural outputs. Development workers often face a fundamental question regarding the access to the market: how much one should travel to reach the nearest market? GLOBAL MARKET TRAVEL TIME CALCULATOR allows users to compute the travel time to the population centers from a given point. Users can select the population size of the city and distance of travel and the tool calculates all the areas with the desired population levels within the desired distance. The result can also be downloaded as a CSV file containing city names, population size and the travel time. Help and support is available in the application.
