High concentrations of vehicular emissions at road intersections are a health-related issue of concern, and the associated fuel consumption is a matter of continuing economic interest. For this study, a computer simulation model called TEXAS-II was developed at the Center for Transportation Research to estimate with respect to time and location the source of carbon monoxide, hydrocarbon, and oxides of nitrogen emissions and the amount of fuel consumed by vehicles as they pass through an intersection. The factors which were used for simulating the intersection environment were (1) intersection size, (2) presence or absence of a special left-turn lane, (3) pretimed signal control, (4) fully-actuated signal control, (5) all-way stop-sign control, (6) traffic volume, (7) number of left turns, and (8) number of heavy-duty vehicles. Traffic engineers and transportation planners can utilize the results of this study in three ways: the predictive models can be applied to calculate the expected source of emissions, fuel consumption, and traffic performance parameters for any intersection situation that was included in the range of simulated conditions; these values can be looked up in a series of tables; and the TEXAS-II computer simulation program can be run to obtain detailed data concerning any specific intersection environment of practical interest.
