16.8 Design Consistency in Rural Driving Motorists make fewer errors when they encounter geometric features that are consistent with their expectations. Inconsistent designs or facility operations violate driver expectations. Expectations for downstream road segments...
15.2 Methods to Increase Driver Yielding at Uncontrolled Crosswalks An uncontrolled crosswalk is in a location that lacks stop or signal control (e.g., midblock intersection). Pedestrians using marked crosswalks and drivers approaching these crosswalks require...
13.12 Determining Work Zone Speed Limits Decisions about work zone speed limits need to account for road geometrics and the location of work zone features (e.g., lane closure tapers, work activity). If possible, keep work zone speed limits within 10 mph of normal...
13.8 Changeable Message Signs The purpose of changeable message signs is to communicate important messages succinctly. Keep display messages to a maximum of two phases. Avoid splitting information across phases, use a consistent format for calendar dates, and make...
13.2 Overview of Work Zone Crashes Young male motorists (ages 25 – 34) are most likely to be involved in work zone crashes. Knowledge of work zones and how they influence safety is valuable for reducing crash risk. Table 13.1 provides general guidance on structuring...
