Network-aware Multi-agent Reinforcement Learning for Adaptive Navigation of Vehicles in a Dynamic Road Network
Traffic congestion in urban road networks is a condition characterized by slower speeds, longer trip times, increased air pollution, and driver frustration. Traffic congestion can be attributed to a volume of traffic that generates demand for space greater than the available street capacity. A …

Quantitative sustainability assessment of pavement-vehicle interaction : from bench-top experiments to integrated road network analysis
The sustainable development of our nation's roadway system requires quantitative means to link infrastructure performance to lifecycle energy use and greenhouse gas (GHG) emissions. Beside surface texture and roughness-induced Pavement-Vehicle Interactions (PVI), we herein recognize that the …

An investigation into the factors affecting the behaviour of Highway Filter Drains, with a particular emphasis on the Scottish Trunk Road Network
… 1500 km (43%) of the strategic Scottish trunk road network drainage asset takes the form of Highway Filter Drains (HFDs). However, despite their popularity, they are prone to clogging, therefore they have an estimated operational life-cycle of ten-years.This research was undertaken to …

Solving the Traveling Salesman Problem via Semantic Segmentation with Convolutional Neural Networks
… a Human Inspired Heuristic (HIH) that converts a road network semantic map into a truncated distance matrix that can be passed to a traditional TSP solution algorithm. The HIH can be further augmented in the image domain with our proposed novel Convolutional Neural Network (CNN). Our proposed CNN …
