Walking survey is applicable over a wider range of weather conditions, including PG stability class A to E/F and calm to medium winds (0–5 m s−1). A driving survey at a low speed (11 mph) can only be conducted under calm to low wind speed conditions (0–3 m s−1) to have an equivalent DP to a walking survey. Only calm wind conditions in PG A (0–1 m s−1) are appropriate for a high driving speed (34 mph). These findings showed that driving survey providers need to optimize the survey schemes to achieve a DP equivalence to the traditional walking survey.]]> Mon, 31 Oct 2022 10:21:47 GMT https://trid.trb.org/View/2031241 A Trajectory Evaluation Platform for Urban Air Mobility (UAM) https://trid.trb.org/View/1994088 Mon, 25 Jul 2022 11:50:54 GMT https://trid.trb.org/View/1994088 A Safety-Aware Real-Time Air Traffic Flow Management Model Under Demand and Capacity Uncertainties https://trid.trb.org/View/1994045 Mon, 25 Jul 2022 11:50:54 GMT https://trid.trb.org/View/1994045 Capacitated Air/Rail Hub Location Problem With Uncertainty: A Model, Efficient Solution Algorithm, and Case Study https://trid.trb.org/View/1994032 $O(n^{4})$ variables and show that the implementation of a Benders decomposition algorithm is inherently hard, because of the cubic number of variables in the master problem. Furthermore, they derive an iterative network design algorithm and additional improvement strategies: MMHUBBI which resolves a restricted problem by the solver CPLEX and MMHUBBI-DIRECT which re-designs the transportation network by a heuristic. Their evaluation on real-world dataset for Chinese domestic transportation shows that MMHUBBI provides a significant speed-up on all instances, compared to using CPLEX, while obtaining near-optimal solutions. MMHUBBI-DIRECT further reduces the runtime/memory usage but provides solutions with worse quality. The authors believe that their study contributes towards the design of more realistic multi-modal hub location problems.]]> Mon, 25 Jul 2022 11:50:54 GMT https://trid.trb.org/View/1994032 A Voice Communication-Augmented Simulation Framework for Aircraft Trajectory Simulation https://trid.trb.org/View/1993944 Mon, 25 Jul 2022 11:50:54 GMT https://trid.trb.org/View/1993944 Breathing air consumption in the fire tests at the Tistbrottet mine https://trid.trb.org/View/1956157 Fri, 20 May 2022 14:06:15 GMT https://trid.trb.org/View/1956157 Deep Learning Architecture for Short-Term Passenger Flow Forecasting in Urban Rail Transit https://trid.trb.org/View/1890125 Mon, 28 Mar 2022 10:29:57 GMT https://trid.trb.org/View/1890125 Drop-in fuels from sunlight and air https://trid.trb.org/View/1902212 thermal pilot-scale solar system operated under field conditions.
