Paratransit and street usage study: Kampala
Video feed analysis for traffic count and machine learning algorithms were blended to describe Kampala’s road network
In Kampala, Uganda, citizens rely completely on informal transportation, in the form of matatus or boda bodas, for all their transportation needs. This reliance, coupled with a lack of regulation, has resulted in over-supply in the paratransit sector.
Transport for Cairo was able to complete 10 weeks’ worth of data collection using our Route Observer application. We observed 1492 trips and 587 routes operating out of Matatu stages across GKMA. Video feeds were used for traffic counts and machine learning algorithms were used to classify vehicles across selected sections for analysis.
Movement in Kampala, Uganda’s capital and home to 1.5 million citizens, is no simple chore.
On an average day, two thirds of trips are completed by privately operated taxis or Matatus; while the majority of the remaining trips are provided by motorcycles or “Boda Bodas”. The former are 14 seater microbuses, and the latter are motorcycles operating privately. At the time of the project, none of these modes were regulated. In addition, of the 2,100km road network on which they operate, only 500kms were paved. Even though the Kampala Capital City Authority is currently paving its roads, the lack of transport regulation resulted in an over-supply in the paratransit sector causing daily traffic congestion, business losses and immobility all over the city.
Over the course of a year, Transport for Cairo has been working on a paratransit and street usage study in preparation for the Bus-Rapid Transit (BRT) pilot project system. The BRT system is envisioned by the government to help alleviate congestion in the Greater Kampala Metropolitan Area (GKMA).
For 10 weeks, the TfC team mapped the public transport network, and provided the operational data necessary to understand the paratransit services in the GKMA area. Through Route Observer (RO), a mobile app developed by TfC, we collected a total of 3200 hours of data points on 1492 trips and 587 routes all over the GKMA. The first steps included using both the data collected during the pilot mapping and secondary sources in order to identify origin and destination points.
Then a standardized list of terminals was periodically uploaded to our Route Observer Dashboard application in order to create assignments for the field researchers. When a field researcher picks an assignment and starts recording on the RO app, the app records both the GPS trace of the trip as well as travel time
Then using Route Snapper, a software developed in-house by TfC, incoming raw traces are processed in batches and migrated to the “Processed Trips” layer in the database.
After data collection, the team created a virtual network of stops in order to model the transportation network. This dataset contributes to the creation of a GTFS with estimated travel times (GTFS feeds are used for trip planning and transport network analysis to evaluate multimodal transport options). Finally, we created a Kampala Bus Map designed to follow the geographic arrangement of the city, while abstracting and simplifying it. The streets shown on the map are simple to read and understand. They are divided into four categories based on street hierarchy, with each category having a different opacity level based on the street’s usage importance. Only the most important streets, defined by the frequency of usage as well as the streets on which the trips are placed, are shown on the map.
Because we know the value of capacity building, we partnered up with World Resource Institute (WRI) and conducted an OpenStreetMap workshop (Mapathon) last January at Makarere University, College of Engineering Design Art and Technology. We worked to raise awareness towards the need for a data management system that can be maintained by locals in order to achieve the most sustainable results in the long run. In collaboration with WRI, the aim of the workshop was to build capacity for students and fresh graduates working with Open Data and OpenStreetMap and to raise awareness on the impact of such platforms and concepts on society. Presenters from Addis Ababa Transport Authority and Accra Ghana talked about their experience in independent data creation and storage. The workshop also incentivized participants to become contributors and active members of their relevant local mapping communities, owning the process of creating and maintaining the data.
