Abstract EN
Environmental pollution problems and energy-saving issues of urban tunnels have increasingly been attracting people’s attention.
The paper aims at investigating a reasonable time factor for CO-based emission factors in the ventilation design of urban road tunnels.
The study results show that the prediction curve of CO-based emission factor for passenger cars consists of two stages.
The average reduction rates of Stage I (2004–2010) and Stage II (2010–2030) are 38% and 14% per year, respectively.
The CO emission factor series of passenger cars conforms to exponential function distribution.
The time factors of CO-based emission backcalculated from the measured data range from 4.9% to 12.6%, which are 2.4–6.3 times the specified value in the Chinese ventilation specification but slightly smaller than predicted ones.
Based on four aspects of predicted results, back analysis results, related references, and engineering applications, it is indicated that the time factor of CO-based emission factor (2%) in the current ventilation specification is conservative.
And when defining 2000 and 2010 as base years, respectively, 4% and 3% can be used as the time factors of CO-based emission factors respectively for the ventilation design of urban tunnels.
This study can provide a reference for ventilation design of urban tunnels in other regions.
