With the growing need for sustainable transportation solutions, understanding the relationship between driving characteristic parameters, vehicle type, and their impact on emissions and fuel consumption over real driving scenarios is becoming increasingly important. In this paper, four conventional vehicles and one hybrid vehicle with different technologies were compared in four distinct routes in Tehran city. Nineteen real driving cycles were generated using widely employed K-means and PCA algorithms.

- Understanding the performance of internal combustion engines is essential for improving emissions and fuel efficiency, particularly in urban settings like Shiraz city, where factors like working days versus holidays play a significant role.
- * The research involved collecting data on vehicle speed and analyzing driving patterns during peak traffic times, utilizing methods like K-means clustering and principal component analysis to create representative driving cycles for testing.
- * Findings revealed that fuel consumption was about 8% higher on holidays due to increased driving times and speeds, which also led to a notable rise in CO and NOx emissions, while HC emissions were higher on working days, underscoring the need for optimizing driving behavior to promote sustainable transport.
Incorporation of fillers might improve the physical properties of sealants. This systematic review and meta-analysis evaluated the retention and caries development rate of filled and unfilled fissure sealants. This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.
