Estimating the perturbed utility route choice model with trip-level data
Mogens Fosgerau, Nikolaj Nielsen, Thomas Rasmussen +1
We provide an estimator for the perturbed utility route choice (PURC) model that works with data at the level of individual trips. The estimator is a nested fixed-point algorithm t…
Sensitivity analysis of the perturbed utility stochastic traffic equilibrium
Mogens Fosgerau, Nikolaj Nielsen, Mads Paulsen +2
This paper develops a sensitivity analysis framework for the perturbed utility route choice (PURC) model and the accompanying stochastic traffic equilibrium model. We derive analyt…
Safe and Operationally Efficient Longitudinal Control of Autonomous Truck Platoons
Alexander Hammerl, Ravi Seshadri, Thomas Kjær Rasmussen +1
This paper presents a hierarchical longitudinal control architecture for autonomous truck platoons that jointly addresses safety, string stability, and economic efficiency. The fra…
Improving Travel Time Reliability with Variable Speed Limits
Alexander Hammerl, Ravi Seshadri, Thomas Kjær Rasmussen +1
This paper analyzes the use of variable speed limits to optimize travel time reliability for commuters. The investigation focuses on a traffic corridor with a bottleneck subject to…
Travel Time Reliability in Stochastic Kinematic Flow Models
Alexander Hammerl, Ravi Seshadri, Thomas Kjær Rasmussen +1
This paper analyzes the time-dependent relationship between the mean and variance of travel time on a single corridor under rush hour like congestion patterns. To model this phenom…
Risk Aware Reservoir Control For Safer Urban Traffic Networks
Alexander Hammerl, Wenlong Jin, Ravi Seshadri +2
We present a risk-aware perimeter-style controller that couples safety and efficiency targets in large, heterogeneous urban traffic networks. The network is compressed into two int…
