ABSTRACT
This research focused on analyzing traffic congestion at cross-intersections using a case
study of Kyaliwajjala-Namugongo junction, Wakiso District-Uganda. The main objective
of this study was to optimize traffic flow at the Kyaliwajjala-Namugongo intersection
using a geometric design.
The study involved carrying out topographic surveys to collect geometric and
topographic data and manual traffic counts of the approaches to determine the
performance of the intersection. The intersection topography was determined using
road profiles generated from the elevation data and Coordinates and performance was
assessed from the traffic volumes and traffic flow movements.
A geometric design was then recommended at the end of this study to enhance the
intersection to cope with the existing and future expected traffic volume. The proposed
design is able to cope with the traffic for a design life of 15 years and installation of
road signs, clear road markings and construction of raised islands were made to cater
for safety of road users.
