Crashes that occur on curved roadways are often more severe than straight road accidents. Previously, most studies focused on the associations between curved sections and roadway geometric characteristics. In this study, significant factors such as driver behavior, roadway features, vehicle factors, and environmental characteristics are identified and involved in analyzing traffic accident severity. Bayesian network analysis was conducted to deal with data, to explore the associations between variables, and to make predictions using these relationships. The results indicated that factors including point of impact, site of location, accident side of road, alcohol/drugs condition, etc., are relatively critical in crashes on horizontal curves. Accident severity increases when crashes occur on bridges. The sensitivity of accident severity to vehicle use, traffic control, point of impact, and alcohol/drugs condition is relatively high. Moreover, a combination of negative factors will aggravate accident severities. The results also proposed some suggestions regarding the design of vehicles, as well as the construction and improvement of curved roadways.

The traditional method of designing wayfinding systems has been used in tourism management for decades. However, the absence of quantitative evaluations for the wayfinding system at tourist resorts may affect information transmission and cause visitors to feel lost. This article proposes a quantitative approach and applies it to the wayfinding system at the Shanghai Disneyland Resort from 2017 to 2019, where the layouts and the contents of wayfinding signboards are systematically evaluated. The analytic hierarchy process is used in conjunction with expert advice to rank 11 elements of content design, and four reasonable indices are calculated to explore the spatial–topological relationships at the tourism resort. According to both the field and expert investigation and tourists’ responses to designed questionnaires, the results show that this method containing content and layout evaluation can enhance tourist satisfaction in certain aspects, thus helping to improve tourism management by considering important indices in wayfinding signage design and modification.
