Desired speed or free speed distributions are important input parameters for microscopic traffic flow simulations. Whereas driven speeds can be measured, desired speeds are not detectable for all vehicles because of vehicles constraining each other. An established approach to estimating desired speed distributions is the modified Kaplan–Meier appro...

This paper extends the concept of a design hourly volume (DHV) which is derived from the “ nth hour” to a concept based on the nth highest saturated hour. To calculate this nth highest saturated hour at each ramp junction of a node, it is necessary to have permanent traffic counts (PTC) on all ramps and the main lanes. In practice, such counts are...

In a parameter study, we systematically varied parameter values, and quantified the resulting traffic flow in each individual lane. We modeled two-, three-, and four-lane freeway sections with the microscopic traffic flow simulation tool PTV Vissim. We compared the results with findings from literature. Simulations using car following model Wiedema...

The blocking of a lane in one direction on an urban two-lane road (referred to as bottlenecks in this paper), receives little attention in current research, although it is a common scenario in traffic. In order to enable automated driving in this situation in the future, this research gap must be closed. An online study with 86 test persons collect...
