Section‐Based Crash Risk Analysis Integrating the Effect of Traffic States and Road Geometry

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This study presents a section‐based crash risk analysis framework that examines the combined effects of traffic conditions and road geometry, with a focus on merging and diverging areas. Findings reveal that diverging sections pose the highest crash risk, especially under significant speed differentials and when the ramp‐to‐mainline flow ratio exceeds ...

Signal Timing and CAV Trajectory Joint Control Under Mixed Vehicular Environments With Hierarchical Proximal Policy Optimisation

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper introduces SVCC‐HPPO, a novel Signal‐Vehicle Cooperative Control framework using an improved Hierarchical Proximal Policy Optimisation (H‐PPO) algorithm to jointly optimise traffic signal timing and Connected/Autonomous Vehicle (CAV) trajectories in mixed traffic environments.

MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

open access: yesIET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...

Game over: Conflict resolution through strategic growth in an invertebrate

open access: yesFunctional Ecology, Volume 40, Issue 1, Page 36-50, January 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In some multimember groups with unequal partitioning of reproduction and poor breeding opportunities outside the group, natural selection has favoured the evolution of adaptive mechanisms such as strategic growth modulation.
