We find that the FC mode achieves the lowest total cost from extending the drone range, increasing deliveries by drones, and reducing driving time and wage costs, with a small trade-off of increasing drone energy consumption.

We develop Krauss, Intelligent Driver Model, and Cooperative Adaptive Cruise Control modules to simulate L0-L5 vehicles. Case studies are conducted to verify the proposed models. Results indicate that higher-level autonomous driving leads to low carbon emissions. The emissions of L5 vehicles are 29% lower compared to L0 vehicles.

Previous research has primarily focused on studying pedestrian movement characteristics in static water scenarios, whereas investigations of pedestrian evacuation under dynamic water flow are still rare. In this study, a series of bottleneck evacuation experiments were performed using a novel experimental flooding setup. Five inflow depths, i.e., 0, 0.3, 0.4, 0.5, and 0.6 m, corresponding to five water flow rates, i.e., 0, 0.225, 0.3, 0.375, and 0.45 m<sup>3</sup>/s, were designed to simulate dynamic water flow in bottleneck layouts. Two evacuation strategies, including individual evacuation and cooperative evacuation, were considered. How inflow depths and evacuation strategies affect density, speed, and nearest-neighbor distribution at the bottleneck is explored. Our findings demonstrate that the pedestrian speed and flow rate in cooperative scenarios are higher than those in individual scenarios. Total evacuation times are 21.7 %, 10.77 %, 5 %, and 14.85 % faster in cooperative scenarios than those in individual scenarios at inflow depths of 0.3, 0.4, 0.5, and 0.6 m.

This paper addresses this gap by adapting carbon abatement cost metrics to transition scenarios and integrating them into AeroMAPS, an open-source model for aviation decarbonisation. These metrics are then used to build Marginal Abatement Cost Curves (MACCs). Rather than directly reading conclusions from them, a novel approach is introduced: integrating MACCs into the model as an indicator of overall scenario cost-effectiveness. Combined with existing scenario metrics, this allows for both scenario evaluation and iterative refinement. By comparing abatement costs to carbon values derived from global policies, sectoral scenarios can be aligned with these. An application to an illustrative aviation decarbonisation scenario shows that energy substitution measures become economically viable only under ambitious policy conditions.
