Description of Research Project
This project is an addition to the mesoscopic modeling project that will be conducted simultaneously. Specifically, this effort will utilize the mesoscopic models to develop macroscopic models that estimate vehicle fuel consumption levels within a transportation planning environment. The input to the model will include the average roadway speed similar to the MOBILE6 model. The team will consider implementing the model in a transportation planning software and testing the procedure against the use of a microscopic analysis.
The research tasks will include the following:
- Gather field data to characterize drive cycles on typical roadways as a function of the roadway speed limit, level of congestion, type of intersection control (stop, yield or traffic signal).
- Develop macroscopic models to estimate vehicle fuel consumption levels using the drive cycles constructed in Task 1.
- Validate the models developed in Task 2 against field observations.
- Implement the models developed in Task 2 in a planning model framework.
- Develop the framework developed in Task 4 against the use of a microscopic modeling framework for different networks.
- Write a final report.
Implementation of Research Outcomes
The models developed in this project will be implemented in a planning model framework so that other researchers can follow suite.
Impacts and Benefits of the Project
The outcome of this project will be better tools for evaluating the energy and environmental impacts of alternative traffic and transportation management strategies.
