Tubman Boulevard Pedestrian Safety Study

Drone observations and field surveys revealing pedestrian risks at unsignalised intersections.

Location: Tubman Boulevard, Monrovia
Client / partner: GIZ Liberia / RSAI
Period: June–December 2023
RSAI’s role: Implementing organization

About the project

RSAI used unmanned aerial vehicle observations to study pedestrian movements and vehicle interactions at unsignalised intersections on Tubman Boulevard.

The research combined aerial and ground-level evidence to understand speed, visibility, crossing behaviour and infrastructure conditions affecting vulnerable road users.

UAV capture of vehicle and pedestrian movements.

Scope of work

Capture aerial traffic movements and synchronise observations with field records.
Count vehicles, turning movements and pedestrian crossings.
Study conflicts, speeds, gap acceptance and road-user perceptions.
Develop and communicate intersection safety recommendations.

RSAI’s contribution

Implementing organization.

Project partners

GIZ Liberia / RSAI.

Documented outputs and progress

Identification of risks associated with vehicle speed, visibility and inadequate crossings.
Recommendations for crossing design, traffic calming and signalisation.
Research findings shared with authorities, transport practitioners and the public.
