Study is aimed to find out what is the representation of IRI (International Roughness Index) from the Roughometer results if it was used as substitute of IRI from the Hawkeye results on the road conditions assessment, which is the hawkeye device is included in the Class I category of roughness measurement devices, while the Roughometer is in the Class III. The Student’s t statistical operation is used to find the representation of IRI from the Roughometer results as substitute of IRI from the Hawkeye results. It is determined by analyzing the comparison of the mean values of both measurement results. The study was conducted on three national road sections in North Sumatra Province, namely: Bts. Kota Binjai – Bts. Kota Medan road with a length of 7,300 meters, Bts. Kota Tebing Tinggi – Bts. Kabupaten Simalungun road with a length of 18,800 meters, and Bts. Kabupaten Simalungun/Bts. Kabupaten Sergai road with a length of 15,000 meters. The IRI values were measured by using Roughometer and Hawkeye devices. The measurements were carried out with the survey team from the Center for Implementation of the National Road II Medan, which was also the facilitators in providing the survey equipment, Roughometer and Hawkeye. The statistical test results that the IRI values from the Roughometer measurement results were significantly different from the IRI values from the Hawkeye measurement results (Ho was rejected) because the Student’s t-test results for the three road sections showed that tcount > tcritical and p-value < 0.05. And the assessment of the road functional conditions using Roughometer showed the same results on one road section but worse results on the other two road sections compared to assessment of the functional conditions with Hawkeye. Based on the analysis results, it can be concluded that the IRI values from Roughometer were more conservative in representing the functional conditions of the road when used as a substitute for the IRI values from Hawkeye.

For the full characterization of the longitudinal road unevenness based on the road elevation power spectral density (PSD), at least two independent indicators are necessary: the unevenness index and the waviness. Yet, for road management purposes, single-number unevenness indicators are still required and a number of such indicators have been proposed to date. The main problem of this issue consists in an adequate combination of the two mentioned indicators to obtain a single indicator whose application would fulfil the requirements, which are sometimes contradictory. The importance of the interaction coupling between the road and the travelling vehicle, in which the vehicle speed also plays a significant role, is emphasized. An alternative single-number indicator is proposed based on the equivalent vibration response effect, which the uneven road causes on the traversing vehicle. Other approaches to this problem are briefly discussed using comparative examples, including the indirect approach, a proposal for the modification of the international roughness index (IRI), and an assessment of the subjective rating methods.

The control of roads traffic, of noise, of all other problems which occur on national road sections are much more manageable through Geographic Information Systems. The possibility of changing parameters in real time from a database, allows rapid information on problems encountered and efficient solutions at a more sustained rate.This paper presents a proposed solution to improve the Geographic Information System by adding noise data, by carrying out a case study on the road section Sag - Voiteg that connects Timisoara (Romania) and Belgrade (Serbia). The existing GIS system was established in 2012 according to the legislation in force at the time. As Year 2017 will mark the next stage of issuing the noise maps according to the rules set by CNOSSOS-EU, the measurements done for this study will follow these new methods. CNOSSOS-EU accurately describes the objectives and methodology requirements, establishes clear criteria for road traffic and sound propagation.The advantage of uniformity standards and methods of control in all EU Member States allows comparative studies on pollution, the number of people affected, etc.

Two Parameters

Road is an infrastructure that built to support the movement of the vehicle from one place to another for different purposes. Today, it is often found damage to road infrastructure, both local roads, and arterial roads. Therefore, to keep the pavement condition to remain reliable, in Indonesia has a periodic program by conducting an objective functional inspection of roads regulated by Bina Marga using the International Roughness Index (IRI). However, the IRI examination is not sufficient to represent the actual field condition; it is necessary to perform subjective functional examination by appraising the road one of them is Pavement Condition Index (PCI, ASTM D 6433). This method has been widely applied in some countries because it has many advantages. However, to do this inspection requires considerable cost, then there needs to be a model to get the relationship between these two parameters of the road. The selected case study was arterial road segment in Medan City, that is in Medan inner ring road. Based on the results of the analysis, there is a difference between the functional conditions of PCI and IRI. The equation derived from these two parameters is by exponential regression equation, with equation IRI = 16.07exp-0.26PCI. with R2 of 59% with correlation coefficient value (r) of -0.768. The value of R2 indicates that PCI gives a strong influence on IRI value.

Early Design Stages

Modeling customer usage in vehicle applications is critical in performing durability simulations and analysis in early design stages. Currently, customer usage is typically based on road roughness (some measure of accumulated suspension travel), but vehicle damage does not vary linearly with the road roughness. Presently, a method for calculating a pseudo damage measure is developed based on the roughness of the road profile, specifically the International Roughness Index (IRI). The IRI and pseudo damage are combined to create a new measure referred to as the road roughness-insensitive pseudo damage. The road roughness-insensitive pseudo damage measure is tested using a weighted distribution of IRI values corresponding to the principal arterial (highways and freeways) road type from the Federal Highway Administration (FHWA) Highway Performance Monitoring System (HPMS) dataset. The weighted IRI distribution is determined using the number of unique IRI occurrences in the functional road type dataset and the Average Annual Daily Traffic (AADT) provided in the FHWA HPMS data.

There are two methods of road assessment, ie, visually and using tools. Visual assessment makes use of the PCI (Pavement Condition Index), while assessment with the Roadroid app can be used to obtain the value of IRI (International Roughness Index) with less cost. Functional assessment of roads in the field more use of visual methods. This method is influenced by the subjectivity of surveyors. Therefore, the assessment using the visual method should be correlated with the assessment method using tools, in order to reduce the subjectivity of road assessment. The research location used is Magetan District Road consisting of 5 road segments. The result shows that the r road assessment using the PCI method has a very good condition, and using IRI Roadroid has a Medium condition. There is a negative (r) correlation between PCI and IRI Roadroid, valued at -0.23. The negative correlation shows that both judgments reversed. Comparison of PCI assessment with IRI Roadroid has a low correlation value and with ttest, yields no comparison of correlation. This result is because the PCI and IRI equally assess the pavement, using different methods.
