Abstract
The objective of this work is to evaluate the heat mitigation
strength on a city-scale of electri cation and automation of the road
transport sector. We present a case study for the city of Singapore
examining the spatio-temporal pro le of the heat emissions due to
road transport for a typical day. We calibrate and validate our
simulation model which is later used for analysis of future electri cation
and automation scenarios. Furthermore, we also evaluate the temporal
energy demand associated with the electri cation of transport and
assess the heat released for the production of this energy. Our results
show a sixfold decrease of the energy usage of the road transport
sector in case of a complete electri cation of all vehicle classes,
which include lorries and vans, private vehicles, taxis, buses, and
motorcycles. Lastly, we study the e ects the presence of autonomous
vehicles might have on the amount of heat produced by road transit.
While autonomous mobility greatly reduces the overall trip durations
as it mitigates congestion, the energy consumption of the sector
remains almost unchanged compared to the fully electric scenario.
