Development of On-Road Exhaust Emission and Fuel Consumption Models for Motorcycles and Application through Traffic Microsimulation

Abstract

This study developed on-road exhaust emission and fuel consumption models for application in traffic microsimulations to estimate motorcycle emissions and fuel consumption in an Asian developing city. The motorcycle onboard measurement system was developed to instantaneously measure and continuously record on-road driving data, including the speed-time profile, exhaust emissions, and fuel consumption per second. The test motorcycle was driven on roads around Khon Kaen City, Thailand, to collect on-road driving data during the morning peak hours for a total of 112 hours. The collected on-road driving data were applied to develop on-road exhaust emission and fuel consumption models using regression analysis. The models were developed with high correlations among the amount of exhaust emissions and fuel consumption and the instantaneous speed and acceleration rate. The developed models were applied with a traffic microsimulation to evaluate the exclusive zone for motorcycles stopping at a signalized intersection. The evaluation results reveal that it could improve the level of intersection service by decreasing travel times, delays, and queue lengths at intersections, as well as by reducing the fuel consumption and emissions of vehicles travelling through intersections compared with these values under the existing conditions.

A framework for development of real-world motorcycle driving cycle in India

“…Since large volumes of data are obtained, their analysis is important to derive the candidate or representative driving cycle. Driving cycles are constructed by various methods like trip based cycle construction, the micro-trip approach 34,35 (Al-Samari et al 2016), cluster analysis, 36–38 the trip segment method, 12 a Markov Chain Monte Carlo simulation for urban mixed roads 13,14,39 (Fries et al, 2018; Li et al 2017) 40,41 , and micro-simulation model 42 (Kumar et al 2012). Trip based and Micro-trip based methods are adapted widely by the researchers in Asian countries.…”

Creative Strategy for Reducing Air Pollution from Motorcycle Exhaust by Urging Urban Motorcyclists to Implement Eco-Riding Techniques

“…Some participants were even able to reduce their fuel consumption by as much as 15.1%, enforcing the effectiveness and viability of fuel-efficient driving [9]. Other studies specifically focused on reducing the carbon emissions of motorcycles have also shown that simply employing idling-stop requirements on red lights and reducing overall idling time can reduce the fuel consumption of motorcycles by 10-19%, CO2 emissions by 18%, and NOx emissions by 6.7% [10] [11].…”

A Model for Sustainable Courier Services: Vehicle Routing with Exclusive Lanes

“…In Taiwan, motorcycles represent 67% of all motor vehicles contributing to 38% of all CO emissions [5,6]. In Thailand, some 56% of all registered motor vehicles are motorcycles [11]. Motorcycles comprise the lion's share of vehicles in Bangkok Metropolitan Region (BMR) with some 20 million in number, which are responsible for 19% of total CO emissions [12].…”

“…However, adhering to (7) in the case would mean satisfying the constraints listed below-only these four constraints are active for the given example. 0 + 0 + 01 ≤ 1 (11) 0 + 0 + 01 ≤ 1 (12) 3 + 3 + 34 ≤ 4 (13)…”
