Comparison of TRANSIMS’ Light Duty Vehicle Emissions with On-Road Emission Measurements [PDF]

Journal of the Transportation Research Forum, 2006
The Transportation Analysis and Simulation System, TRANSIMS, contains a vehicle emissions module that estimates tailpipe emissions for light and heavy-duty vehicles and evaporative emissions for light-duty vehicles. This paper describes and validates the TRANSIMS emission module and compares its emission estimates to on-road emission-measurements and ...

TRANSIMS Implementation for a Small Network and Comparison with Enhanced Four-Step Model [PDF]

Journal of the Transportation Research Forum, 2014
Travel demand forecasting is a major tool to assist decision makers in transportation planning. While the conventional four-step trip-based approach is the dominant method to perform travel demand analysis, behavioral advances have been made in the past decade.

Extending TRANSIMS Technology to an Integrated Multilevel Representation [PDF]

, 2005
The TRANSIMS system developed at Los Alamos in the USA over the past decade is a world leader in providing an integrated land-use transportation dynamical model for large areas with a million or more inhabitants. TRANSIMS uses standard survey data to create synthetic micropopulations, including family structure, to simulate trip making and emergent ...

Artificial Intelligence Applied on Traffic Planning and Management for Rail Transport: A Review and Perspective

Discrete Dynamics in Nature and Society, Volume 2023, Issue 1, 2023., 2023
Artificial intelligence (AI) has received much attention in the domain of railway traffic planning and management (TPM) from academia and industries. While many promising applications have been reported, there remains a lack of detailed review of the many AI models/algorithms and their uses and adaptations in rail TPM. To fill this gap, this systematic

Vehicle Routing Simulation for Prediction of Commuter’s Behaviour

Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022
We propose a multiagent, large‐scale, vehicle routing modeling framework for the simulation of transportation system. The goal of this paper is twofold. Firstly, we investigate how individual and social knowledge interact and ultimately influence the effectiveness of resulting traffic flow.

Research on Optimization Model of Logistics Transportation Truck Path considering Environmental Impact: Experimental Data from Xiqing District, Tianjin

Journal of Advanced Transportation, Volume 2021, Issue 1, 2021., 2021
In recent years, the prohibition of trucks which could cause environmental pollution on urban roads has become widespread in China. However, some truck restriction policies might lead to a reduction in logistics transportation efficiency. With the help of big data, technology companies have developed many truck applications, such as HCB, truck home ...
