Modeling Vehicle Fuel Consumption and Emissions at Signalized Intersection Approaches: Integrating Field-Collected Data Into Microscopic Simulation.

摘要

Microscopic models produce emissions and fuel consumption estimates with higher temporal resolution than other scales of models. Most emissions and fuel consumption models were developed with data from dynamometer testing which are sufficiently accurate for macroscopic level emissions inventories. The primary goal of this project is to improve the microscopic modeling of emission and fuel consumption by integrating detailed vehicle data into the simulation. The proposed approach combines a microscopic traffic simulation model (VISSIM) with detailed emissions and fuel consumption data that is either collected in the field or obtained from an existing emission inventory dataset. The project also examines the possibility of using the vehicles on-board diagnostic board (OBD) to record real-time engine and emissions data at a high temporal resolution. The outcome of this project provides transportation operators with a model that is capable of reliably estimating the environmental impact of various traffic management policies at the microscopic modeling and would fill a gap that currently exists in traffic modeling capabilities.
