[sumo-user] TripInfo Questions
|
Hello. I've performed two different simulations, keeping the settings of a
vehicle constant. I'd like to know:
1 - Are start times, travel times, etc. rounded up to integer values?
2 - How can this vehicle have the same travel time, but different emission
values?
3 - And how can it be possible that CO emissions increase and CO2 and NOx
emissions decrease in the same simulation? I mean, if the emission of one
pollutant increases, the others should not increase as well?
The values obtained are listed below, and the values that cause the doubts
are highlighted.
*Simulation 1:*
<tripinfo id="car_179" depart="24.00" departLane="350448292#2_0"
departPos="2.54" departSpeed="0.00" departDelay="6.00" arrival="367.00"
arrivalLane="40566417#0_0" arrivalPos="69.19" arrivalSpeed="13.63"
*duration="343.00"* routeLength="2237.11" waitSteps="35" timeLoss="191.13"
rerouteNo="0" devices="tripinfo_car_179 emissions_car_179" vType="type1"
speedFactor="1.00" vaporized="">
<emissions *CO_abs="15694.521297" (LOWER value than in Simulation
2) CO2_abs="656916.034438"* (*Value GREATER than in simulation 2)
*HC_abs="86.451205"
PMx_abs="10.347551" *NOx_abs="260.984597"* (*Value GREATER than in
simulation 2)*fuel_abs="282.386748" electricity_abs="0"/>
</tripinfo>
*Simulation 2:*
<tripinfo id="car_179" depart="24.00" departLane="350448292#2_0"

arrivalLane="40566417#0_0" arrivalPos="69.19" arrivalSpeed="10.89"
*duration="343.00"* routeLength="2237.11" waitSteps="36" timeLoss="191.71"
rerouteNo="0" devices="tripinfo_car_179 emissions_car_179" vType="type1"
speedFactor="1.00" vaporized="">
<emissions *CO_abs="15745.283879" CO2_abs="648527.699997"*
HC_abs="86.500195"
PMx_abs="10.262906" *NOx_abs="258.047515"* fuel_abs="278.781012"
