In this work we report the driving cycle obtained for a tropical city located at high altitude and the emission factors of the vehicles that circulate in this city. For this purpose, the operation of 20 light vehicles was observed, of the 10 vehicle manufacturers with the highest demand in the town, powered by 92 and 87 octane gasolines. A Global Positioning System (GPS), a portable vehicle emissions analyzer and an interface to access information from the Electronic Control Module (ECM) through the On-Board Diagnostic (OBD) system were used. Simultaneous second by second measurements of position, speed, fuel consumption, tailpipe emissions of CO2, CO, THC, NOx, O2 were obtained for 8 months. Based on this database, the representative cycle was obtained by means of the micro trips method, which has a duration of 800 ± 60 seconds and an average speed of 22 km/h. Additionally, it was obtained that the average fuel consumption of the vehicles was 13.3 km/l and the CO and NOx emissions factors were 4 and 0.28 gr/km, respectively. These values are similar to those observed in other cities.
