Bali’s Traffic Assessment

Bali’s Traffic Assessment#

The Transportation Team in Bali will be assessing congestion in the island.

The following study leverages proprietary data from Grabmaps and Waze, kindly obtained through the Development Data Partnership and open-source data from Open Street Map and Meta. These data sources allow us, on the one hand, to examine the state of congestion — for example, its effects on travel times, its spatial, daily, and hourly distribution, and the locations where most accidents occur. On the other hand, we use them to calculate the Connected Communities indicator for existing and proposed transit systems, in order to understand how many people live within the systems’ catchment areas and what their relative wealth is.

A key advantage of these alternative data sources is their high resolution. For instance, GrabMaps and Waze provide data at the street level every hour (Grab1) and every two minutes (Waze), while Meta provides data at a 2.4 km² resolution, and OpenStreetMap is continuously updated by its community of contributors. This granularity enables analyses that would otherwise not be possible at such fine scales.
