Sustainable Highway Design: Disentangling the Effects of Geometric-Related and Traffic-Related Factors on Urban Highway Traffic Emissions

Radical precursors and related species from traffic as observed and modeled at an urban highway junction.

Nitrous acid (HONO) and formaldehyde (HCHO) are important precursors for radicals and are believed to favor ozone formation significantly. Traffic emission data for both compounds are scarce and mostly outdated. A better knowledge of today's HCHO and HONO emissions related to traffic is needed to refine air quality models. Here the authors report results from continuous ambient air measurements...

Modeling Highway Traffic Volumes

The behavior of vehicular traffic is subject to many irregularities and stochastic fluctuations. Thus, our success in solving a variety of traffic management and optimizations tasks, such as accident detection or optimal vehicle routing, depends heavily on our ability to adequately model, reason about and predict such a behavior. The objective of this work is to develop a probabilistic model of...

Effects of Passing Lanes on Highway Traffic Flow

In this paper, the effects of passing lanes on traffic flow on a single-lane highway are investigated based on a cellular-automaton (CA) model proposed by Lee et al. (Phys. Rev. Lett. 92, 238702 (2004)) with periodic boundary conditions. A new driving strategy for the diverging and interacting processes are proposed by considering dual-time-headways (an interaction headway and a safe headway) a...

Agent-based Highway Traffic Simulation

This paper focuses on the multi-agent highway traffic simulation. It provides a realistic modeling with high fidelity continuous vehicle movement incorporating physical dynamics of the vehicles. The deliberative agent part of the system enables to implement and evaluate complex cooperation and coordination algorithms. The paper presents the architecture and implemented simulator for evaluation ...
