Comparative Study of Determining the Value of Road Inequality Based on Visual Observations and Parvid Tools

Introduction

Road inequality, or corrugated road conditions, is a serious problem that affects driving comfort and safety. Damaged roads can lead to increased maintenance costs and pose a risk to motorists. To measure the level of road inequality, two methods are commonly used: visual observations and the use of measuring instruments. This comparative study aims to investigate the effectiveness of these two methods in determining the value of road inequality.

Background

Road inequality is a widespread problem that affects many countries. It is caused by various factors, including heavy traffic, poor road design, and inadequate maintenance. The consequences of road inequality can be severe, including increased maintenance costs, reduced driving comfort, and compromised safety. To address this issue, it is essential to have accurate and reliable methods for measuring road inequality.

Methods

This study employed two methods to determine the value of road inequality: visual observations and the use of measuring instruments. Visual observations rely on the subjective assessment of an observer, using the Surface Distress Index (SDI) method. On the other hand, the Parvid tool uses a Naasra roughometer to obtain objective data in the form of the International Roughness Index (IRI).

Results

The research conducted in this study revealed four equations of correlation between the value of SDI and IRI on various roads. Interestingly, the SP.Sitonggor-BTS. Tobasa road section showed the strongest correlation with the IRI equation = 0.257Sdi + 0.790 and the R2 value is 0.825. The value of R2 indicates that the higher the value, the stronger the correlation between the two parameters.

Discussion

The results of this study indicate that although visual observation methods have weaknesses due to their subjective nature, this method can be an effective tool for estimating the value of road inequality. This is particularly important because the visual method is more accessible and cheaper than the use of measuring devices. However, it is essential to note that the visual method has limitations in measuring road inequality in a precise way. The use of measuring devices such as Parvid is still needed to obtain more accurate and objective data.

Conclusion

This comparative study highlights the importance of understanding the methods used to determine the value of road inequality. The results of this study demonstrate that visual observation methods can be an effective tool for estimating road inequality, particularly when combined with the use of measuring devices. The combination of these two methods can provide a more complete picture of road conditions and help in determining effective and targeted maintenance strategies.

Recommendations

Based on the findings of this study, the following recommendations are made:

The use of visual observation methods should be encouraged as a cost-effective and accessible tool for estimating road inequality.
The use of measuring devices such as Parvid should be continued to obtain more accurate and objective data.
The combination of visual observation methods and measuring devices should be used to provide a more complete picture of road conditions.
Further research should be conducted to investigate the effectiveness of other methods for determining the value of road inequality.

Future Research Directions

This study has highlighted the importance of understanding the methods used to determine the value of road inequality. Future research should focus on investigating the effectiveness of other methods, including the use of advanced technologies such as artificial intelligence and machine learning. Additionally, research should be conducted to investigate the impact of road inequality on driving comfort and safety.

Limitations of the Study

This study has several limitations, including:

The study was conducted on a limited number of roads, which may not be representative of all road conditions.
The study relied on subjective assessment of observers, which may introduce bias.
The study did not investigate the impact of road inequality on driving comfort and safety.

Conclusion

In conclusion, this comparative study has highlighted the importance of understanding the methods used to determine the value of road inequality. The results of this study demonstrate that visual observation methods can be an effective tool for estimating road inequality, particularly when combined with the use of measuring devices. The combination of these two methods can provide a more complete picture of road conditions and help in determining effective and targeted maintenance strategies.
