This research investigates how land use changes due to sea level rise (SLR) may affect traffic network congestion and how preventive protection measures against SLR can significantly improve transportation network performance and possibly be cost effective. We use the San Francisco Bay Area shoreline, under a one-meter SLR, as a case study, and evaluate the results with different metrics: the number of commuters that are not able to execute their trip, and the Vehicle Hours Traveled increase. Our model considers both hydrodynamic and traffic effects. The results show that the relocation of commercial and residential buildings from inundated to dry areas will increase congestion levels, while preventive protection of the shoreline leads to lower levels of traffic congestion. Finally, we discuss other possible costs related to the absence of levee protection that should be evaluated by policy makers before developing SLR adaptation strategies.

这项研究调查了由于海平面上升（SLR）引起的土地利用变化如何影响交通网络拥堵，以及针对SLR的预防性保护措施如何能够显着改善交通网络的性能并可能具有成本效益。我们以一米SLR下的旧金山湾区海岸线为案例研究，并以不同的指标评估结果：无法执行行程的通勤人数，以及增加的车辆行驶时间。我们的模型同时考虑了水动力效应和交通效应。结果表明，将商业和住宅建筑从淹没区迁移到干旱地区将增加拥堵程度，而对海岸线的预防性保护则可降低交通拥堵程度。最后，
