Identification of road networks and optimal routes directly from remote\nsensing is of critical importance to a broad array of humanitarian and\ncommercial applications. Yet while identification of road pixels has been\nattempted before, estimation of route travel times from overhead imagery\nremains a novel problem, particularly for off-nadir overhead imagery. To this\nend, we extract road networks with travel time estimates from the SpaceNet MVOI\ndataset. Utilizing the CRESIv2 framework, we demonstrate the ability to extract\nroad networks in various observation angles and quantify performance at 27\nunique nadir angles with the graph-theoretic APLS_length and APLS_time metrics.\nA minimal gap of 0.03 between APLS_length and APLS_time scores indicates that\nour approach yields speed limits and travel times with very high fidelity. We\nalso explore the utility of incorporating all available angles during model\ntraining, and find a peak score of APLS_time = 0.56. The combined model\nexhibits greatly improved robustness over angle-specific models, despite the\nvery different appearance of road networks at extremely oblique off-nadir\nangles versus images captured from directly overhead.\n
