Introduction

Uneven road conditions can have a significant impact on driving comfort, making it essential to regularly examine road conditions to measure the level of irregularity of the road surface. This is crucial for planning maintenance or improvement of the right road. One way to measure road irregularities is to use the International Roughness Index (IRI). However, the measurement of road inequality often does not reflect the actual conditions on the ground, mainly because the survey results only represent the conditions in the place where the roughness sensor is installed.

The Importance of Accurate Road Irregularity Measurement

Accurate measurement of road irregularities is vital for several reasons. Firstly, it helps to identify areas that require maintenance or improvement, ensuring that resources are allocated effectively. Secondly, it enables road authorities to plan and implement strategies to reduce road irregularities, thereby improving driving comfort and safety. Finally, accurate measurement of road irregularity can help to reduce the risk of accidents caused by uneven road conditions.

Methodology

In this study, the Arrb Roughometer III was used to measure the irregularity of the road on the Medan-Binjai Road (TD Pardede-LATERSIA RSU) along 7 km. Measurements were made in four lanes in both directions, with the sensor placement on the right to measure the condition of the road surface that is passed by the right tire of the vehicle, and on the left for the left tire. By comparing the jealous value generated from these two sensor positions, we can get a more accurate picture of road irregularities.

Results

The results of the analysis show that in slow lanes in the direction of Medan-Binjai, the average value of the envy between the right and left tires is 3.03 m/km and 3.28 m/km. Meanwhile, for fast lanes, the average value is 3.26 m/km for the right tire and 3.07 m/km for the left tire. Whereas in the direction of Binjai-Medan, the ratio of the average jealous value in slow lanes is 4.10 m/km for right tires and 3.95 m/km for left tires, and on fast lane, 4.20 m/km for tires right and 3.94 m/km for the left tire.

Discussion

From this result, there is a difference in the value of the envy between right and left wheelpaths. Nevertheless, the difference detected between the placement of the sensor on both sides is not significant, only around the difference of 0.26. This shows that although there are variations, the effect of the sensor position on the measurement results is not too large, both on fast or slow lane. However, the condition of the incomplete road in the direction of Binjai-Medan shows a clear difference and requires a different maintenance approach.

Conclusion

Further analysis of the data obtained shows that although the placement of the sensor provides valuable information about the condition of the road surface, more comprehensive supervision is still needed and a deeper analysis method to understand the overall unhappiness. Using both sensor positions can enrich data, but other factors such as the type of road material, rainfall, and vehicle use also need to be taken into account to determine more effective improvement steps.

Implications for Road Maintenance Policies

In the context of road maintenance policies, the results of this study are important to consider in making appropriate improvement and maintenance strategies. With accurate information regarding road irregularities, related parties can plan more efficient and effective actions to increase driving comfort and safety of road users.

Recommendations

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

  • More comprehensive supervision is needed to understand the overall unhappiness of road users.
  • A deeper analysis method is required to understand the factors that contribute to road irregularities.
  • The use of both sensor positions can enrich data, but other factors such as the type of road material, rainfall, and vehicle use also need to be taken into account to determine more effective improvement steps.
  • Road maintenance policies should consider the results of this study in making appropriate improvement and maintenance strategies.

Limitations

This study has several limitations. Firstly, the study only measured road irregularities on a single road, and therefore, the results may not be generalizable to other roads. Secondly, the study only used two sensor positions, and therefore, the results may not be representative of the actual conditions on the ground. Finally, the study did not consider other factors that may contribute to road irregularities, such as the type of road material, rainfall, and vehicle use.

Future Research Directions

Future research should aim to address the limitations of this study. This can be achieved by:

  • Conducting a more comprehensive study that measures road irregularities on multiple roads.
  • Using more sensor positions to get a more accurate picture of road irregularities.
  • Considering other factors that may contribute to road irregularities, such as the type of road material, rainfall, and vehicle use.
