Abstract: Most of previous studies have focused on the entire trips in a geographic region, while few of them addressed those induced by a city landmark. To address it, this paper explores the trips and their CO2 emissions induced by a shopping center from a time-space perspective and their usage in relocation planning. This is done by the mean of a case study in the city of Borlänge in mid-Sweden, where the trips, to the town’s largest shopping mall in its center, are examined. To do so, we adopt GPS tracking data of car trips that end and start at the shopping center. Thereafter, (1) we analyze the traffic emission patterns from a time-space perspective, where temporal patterns reveal an hourly-based traffic emission dynamics and spatial patterns uncover a heterogeneous distribution of traffic emissions in spatial areas and individual street segments. Further, (2) this study reports that most of the observed trips follow an optimal route in terms of CO2 emissions. In this respect, (3) we evaluate how well located the current shopping center is through a comparison with two competing locations, and we conclude that the two suggested locations, which are close to the current shopping center, do not show a significant improvement in term of CO2 emissions.
