Bill N Posted May 20, 2019 Share Posted May 20, 2019 Description: Allow the user to set different reference speeds for different types of roads. Use Case: A user may drive sticking firmly to the speed limit in urban areas - they would therefore set the reference speed of urban roads (for example, roads with a speed limit below 50mph) to no more than 100%. For other roads, a user may drive with the traffic flow (slightly above the speed limit) - they would therefore set the reference speed of non-urban roads (for example, roads with a speed limit above 50mph) to, say, 107%. NOTE: I am also not entirely clear how the reference speeds works - does ABRP use any data sources which estimate the likely speed along a particular stretch of road at different times of day?
