“…The DG-100 GPS will record the time, travelling speed, altitude and location of each monitored vehicle a second-by-second basis. To get BRT emissions, the speed recapitulation results from GPS are estimated for fuel consumption according to the formula for calculating fuel consumption for large buses in the previous article (Huboyo et al, 2017). The fuel consumption results are used to predict vehicle emissions based on the database in CORINAIR (European Environment Agency, 2021).…”

Abating the air emission related to the transportation sector by operation of the Bus Rapid Transport (BRT) system has been adopted in Indonesia. This study was conducted to obtain an overview of the implementation of BRT, the success of shifting private vehicles to BRT, and the number of emissions resulting from the operation of BRT. The study was conducted using a questionnaire and observations in BRT vehicles. A questionnaire survey was conducted randomly across Semarang sub-districts for 701 private vehicles consisting of cars and motorcycles in a parking lot. Questionnaires were distributed to BRT users in the waiting room and among those who left the BRT. The emission quantity is obtained from GPS observations installed in the BRT and quantified by the emission generation equation based on the bus speed. Even though they are not BRT users for daily activities, motorcycle users use BRT more frequently than private car users. For the private car and motorcycle users, the BRT coverage area is the first barrier to using the BRT system, followed by travel time (due to congestion and traffic jams). Based on current BRT users, the shifting of motorcycle users is far higher than private car users. About 30% of public transport users (besides BRT) shift to BRT users. The BRT emissions (CO and TSP) in the east-west corridor on weekdays and weekends are higher than those in the south-north corridor. Based on this study's results, the BRT application has not significantly reduced the use of private vehicles. Instead, shifting occurs from former public transport to BRT. BRT emissions are related to traffic route conditions and topography. BRT implementation needs to comprehensively consider social, economic and technical (infrastructure) aspects.

According to the Air Quality Live Index (AQLI), Indonesia's air quality has continued to deteriorate in the last two decades, so Indonesia is officially ranked 17th as the country with the worst air quality in the world. This is due to the population explosion in Indonesia causing industrial activity to also increase. The high levels of exhaust emissions in vehicles, of course, requires the need for technology to measure vehicle exhaust gases to reduce the impact of air pollution. However, the procurement of exhaust emission test equipment is still expensive, so only certain class workshops have this tool. In addition, the reading results of the vehicle's OBD (On Board Diagnostic) system are only able to display the condition or reading value of the Lambda sensor because other gas sensors readings such as CO2, HC, and CO cannot be displayed on the OBD reading results. The purpose of this study is to describe the design of the tool and the results of measuring CO and HC levels through the Blynk application. Research methods that use several gas sensors, such as MQ-7 and TGS-2602 (CO gas) and MQ-2 and TGS-2611 (HC gas), are then compared with the measurement results of a standard gas analyzer. The results showed that the MQ-7 value is close to the accuracy at 1000 rpm and 5000 rpm, namely 99.68% and 99.49%, while the level of accuracy at 3000 rpm is 99.37%. The TGS-2602 sensor at 1000 rpm only has the best accuracy and accuracy, namely 99.67% and 99.77%. The level of accuracy of the MQ-2 sensor has the best value at 1000 rpm rotation, which is 95.71% and the level of accuracy has the highest value at 7000 rpm rotation, which is 100%. For the level of accuracy of the TGS-2611 sensor, it has an accuracy level of 1000 rpm rotation of 94.65% and the level of accuracy of the sensor obtains very good values at 1000 rpm, 7000 rpm, and 9000 rpm rotation of 100%.

Decline in air quality over the years has been linked to the growing rate of urbanization and the increase in the number of vehicles plying the roads. The focus of this study is to monitor the incidence of vehicular emissions in some parts of Benin City and employ geostatistical techniques such as kriging interpolation to study the spatial distribution of some selected pollutants around the study area. Seven (7) georeferenced points, namely; University of Benin Main Gate, Ekosodin junction, Agen Junction, Super D junction, Nitel junction, Okhunmwun junction and Oluku Market junction were used for data collection. Pollutant from vehicular emission, namely; dinitrogen oxide (NO2), carbon monoxide (CO) including the total radiation were monitored in the morning and evening for a period of 35 days (7th July to 12th August 2020) with the aid of portable toxic gas monitors and radiation alert meters. Other parameters of interest which were also measured include; maximum temperature and wind speed using infra-red thermometers and portable anemometer. To ascertain the quality of the data, selected preliminary analysis, namely; test of normality, test of homogeneity, outlier detection and reliability test were done. Results of the study revealed a growing concentration of CO and NO2 around Ugbowo maingate and Okhunmwun community especially during the peak hours.
