Transportation networks underpin
socioeconomic development by enabling the movement of goods
and people. However, little is known about how flooding
disrupts transportation systems in urban areas in developing
country cities, despite these natural disasters occurring
frequently. This study documents the channels through which
regular flooding in Kinshasa, the Democratic Republic of
Congo, impacts transport services, commuters' ability
to reach their jobs, and the associated economic opportunity
costs from travel delays. This assessment is based on
transit feed specification data sets collected specifically
for this analysis under normal and flooded conditions. These
data sets were combined with travel survey data containing
travelers' socioeconomic attributes and trip
parameters, as well as a high-resolution flood maps. The
results show that (1) flood disruptions cause increases in
public transit headways and transit re-routing, decreases in
travel speeds, and thus travel time delays, which translate
into substantial economic costs to local commuters; (2)
accessibility to jobs decreases under flooded conditions,
hindering the establishment of an integrated citywide labor
market; (3) there are spatial clusters where some of the
poorest commuters experience among the highest travel
delays, highlighting socio-spatial equity aspects of floods;
(4) certain road segments are critical for the transport
network and should be prioritized for resilience measures;
and (5) the estimated daily cost of flood disruption to
commuters’ trips in Kinshasa is $1,166,000. The findings of
this assessment provide disaster mitigation guidance to the
Office des Voiries et Drainage under the Ministry of
Infrastructure, as well as strategic investment
recommendations to the Ministry of Housing and Planning. |
