The 16th World Conference on Transport Research Society (WCTRS) Conference in Montreal was postponed to 17-24 July 2023 due to the many difficulties for worldwide travel during the pandemic. 

At WCTR 2023 Montréal, SIGA2 featured 10 regular and 5 special sessions, totalling 60 very interesting and relevant presentations on key issues in the domains of maritime transport, ports and their hinterlands. Core topics included ‘classics’ such as maritime planning and routing, port macro impacts, port strategies, and port hinterland connections. Furthermore, the emerging topic of digitalisation featured in two regular sessions concerning respectively maritime transportation and ports, and also in one special session. Next, also the greening topic featured in one regular port greening session, and one special session. Finally, COVID still got attention with a special session, as did the topic of geopolitics. The selected and positively reviewed papers will now be submitted to a selection of three scientific journals (Case Studies on Transport Policy; Sustainability; Journal of Maritime Affairs) and one book on port greening (with Palgrave).
