Impact of Road Pavement Condition on Vehicular Free Flow Speed, Vibration and In-Vehicle Noise

Abstract

Road infrastructure in good condition is a key requirement for efficient transportation systems which leads to economic prosperity and improved quality of life. However, road surface conditions deteriorate over time according to traffic loads and environmental factors. Poor road conditions lead to congestion, accidents, lost productivity, and driver fatigue. This work considers the relationship between road pavement condition and vehicle speed, vibration, and in-vehicle noise. A 7 km section of the Grand Trunk Road, Peshawar, Pakistan divided into 280 segments (140 for each lane), of length 50 m was observed and the Pavement Condition Index (PCI) of each segment was determined based on the recurrent distress type and density according to ASTM D6433-011 guidelines. The number of very good, satisfactory, fair, poor, and very poor conditions are 51, 52, 81, 48, and 42, respectively. The mobile app BotlnckDectr was employed to measure vehicle speed, RPM, noise, vibration, GPS location, and time. Statistical analysis was employed to determine the relationship between PCI and vehicle speed, vibration, and in-vehicle noise. The results obtained indicate that noise and vibration increase by 3.3% and more than 30%, respectively, as the pavement condition changes from good to very poor, and vehicle speed decreases by 8.8%.

Pengembangan Sistem Informasi JaBol Sebagai Sarana Pelaporan dan Edukasi Jalan Rusak

“…Pertama, jalan yang terawat dengan permukaan yang mulus, serta bermarka yang baik memungkinkan kendaraan beroperasi lebih efisien, sehingga menghasilkan biaya pemeliharaan yang kecil dan meningkatnya keefisiensian bahan bakar [5]. Kedua, kondisi jalan yang buruk dapat menyebabkan kemacetan lalu lintas, kecelakaan, penurunan produktivitas, dan kelelahan pengemudi [6]. Selain itu, pemeliharaan jalan yang efektif membantu penjaminan kualitas transportasi di kota mana pun dengan memperbarui inventaris jaringan jalan dan mendeteksi tahap awal kerusakan jalan [7].…”

Assessment of asphalt pavement aging condition based on GF-2 high-resolution remote sensing image

“…With the advancement of computer and sensor technologies, advanced sensors and devices, such as onboard laser detectors and image acquisition systems, have been developed for the detection of road conditions. [6][7][8][9] They are capable of obtaining real-time information regarding the condition of the road and are capable of performing qualitative diagnosis and quantitative evaluation analysis to support scientific maintenance decisions. [10][11][12] The use of these technologies has disadvantages, such as the obstruction of traffic and the delay in obtaining information regarding the condition of the entire section, as well as the time required to conduct the sampling survey.…”

Alternative Method for Determination of Vibroacoustic Material Parameters for Building Applications

“…This translates into shortening the travel time of city residents, which is undoubtedly a desirable phenomenon [ 12 , 13 , 14 ]. However, the price for such a development is the increased presence of bothersome stimuli, such as noise and vibrations, especially from the railway infrastructure [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ].…”
