Optimal Control of Reserve Asset Portfolios for Stablecoins
Alexander Hammerl
Stablecoins promise par convertibility, yet issuers must balance immediate liquidity against yield on reserves to keep the peg credible. We study this treasury problem as a continu…
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…
Optimal Evacuation Control in Large Urban Networks With Stochastic Demand
Alexander Hammerl, Wenlong Jin, Ravi Seshadri +2
We develop a risk-aware Model Predictive Control (MPC) framework for large-scale vehicular evacuations. Traffic dynamics are captured by the Generalized Bathtub Model, which descri…
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…
