Systematic Framework

In winter, it is critical for cold regions to have a full understanding of the spatial variation of road surface conditions such that hot spots (e.g., black ice) can be identified for an effective mobilization of winter road maintenance operations. Acknowledging the limitations in present study, this paper proposes a systematic framework to estimate road surface temperature (RST) via the geographic information system (GIS). The proposed method uses a robust regression kriging method to take account for various geographical factors that may affect the variation of RST. A case study of highway segments in Alberta, Canada is used to demonstrate the feasibility and applicability of the method proposed herein. The findings of this study suggest that the geostatistical modelling framework proposed in this paper can accurately estimate RST with help of various covariates included in the model and further promote the possibility of continuous monitoring and visualization of road surface conditions.

Prasarana jalan jika terbebani volume lalu lintas yang tinggi dan berulang-ulang akan menyebabkan terjadinya penurunan kualitas jalan sehingga dapat mempengaruhi keamanan, kenyamanan dan kelancaran dalam berlalu lintas. Untuk menjaga agar tidak terjadi penurunan kondisi khususnya pada jalan poros Kecamatan Sabbang Selatan Kabupaten Luwu Utara tepatnya di jalan Padang Sarre, Buntu Terpedo sampai jalan Dandang sepanjang 4 km perlu adanya penanganan. Maka perlu dilakukan penelitian awal terhadap kondisi permukaan jalan dengan melakukan survei secara visual dengan cara menganalisa kerusakan berdasarkan jenis dantingkat kerusakannya. Tujuan penelitian yaitu menilai kondisi perkerasan danpenanganan sesuai kondisi permukaan jalan. Penelitian ini menggunakan system penilaian kondisi perkerasan menurut Bina Marga dengan perhitungan Surface Distress Index (SDI) untuk jalan beraspal. Dari hasil penelitian di dapatkan penilaian untuk jenis kerusakan permukaan jalan pada ruas kanan yaitu retak pinggir 1,183%, lubang 0,031%, amblas 0,054%, retak kulit buaya 3,271%, retak kotak-kotak 3,222%, tambalan 0,033% dan pengelupasan butir 0,013%. Sedangkan untuk ruas kiri yaitu retak pinggir 0,035%, lubang 0,051%, amblas 0,000%, retak kulit buaya 0,130%, retak kotak-kotak 2,351%, tambalan 0,000% dan pengelupasan butir 0,150%. Kondisi perkerasan jalan yang menjadi objek penelitian sepanjang 4 km yaitu 85% baik, 0% sedang, 15% rusak ringan, 0% rusakberat.Road infrastructure if it is burdened by high and repetitive traffic volumes will cause a decrease in road quality so that it can affect safety, comfort and smoothness in traffic. To prevent deterioration in conditions, especially on the axis road of South Sabbang District, North Luwu Regency, precisely on Padang Sarre road, Buntu Terpedo to Dandang road along 4 km, it needs handling. So it is necessary to conduct an initial research on road surface conditions by conducting a visual survey by analyzing the damage based on the type and level of damage. The research objective was to assess pavement conditions and handling according to road surface conditions. This study uses a pavement condition assessment system according to Bina Marga with the calculation of the Surface Distress Index (SDI) for asphalt roads. From the research results obtained an assessment for the type of road surface damage on the right side, namely edge cracks 1.183%, holes 0.031%, collapse 0.054%, crocodile skin cracks 3.271%, checkered cracks 3.222%, 0.033% patches and 0.013% peeling grains. Whereas for the left section, the edges cracked 0.035%, holes 0.051%, collapsed 0.000%, crocodile skin cracks 0.130%, checkered cracks 2.351%, fillings 0.000% and peeling 0.150%. The condition of the pavement which is the object of the research along 4 km is 85% good, 0% moderate, 15% lightly damaged, 0% heavily damaged.

Damage Data

Road surface conditions have a direct effect on the quality of driving, which in turn affects overall traffic flow. Many studies have been conducted to accurately identify road surface conditions using diverse technologies. However, these previously proposed methods may still be insufficient to estimate actual risks along the roads because the exact road risk levels cannot be determined from only road surface damage data. The actual risk level of the road must be derived by considering both the road surface damage data as well as other factors such as speed. In this study, the road hazard index is proposed using smartphone-obtained pothole and traffic data to represent the level of risk due to road surface conditions. The relevant algorithm and its operating system are developed to produce the estimated index values that are classified into four levels of road risk. This road hazard index can assist road agencies in establishing road maintenance plans and budgets and will allow drivers to minimize the risk of accidents by adjusting their driving speeds in advance of dangerous road conditions. To demonstrate the proposed risk hazard assessment methodology, road hazards were assessed along specific test road sections based on observed pothole and historical travel speed data. It was found that the proposed methodology provides a rational method for improving traffic safety.

To facilitate more efficient winter maintenance decision support, road weather information systems (RWIS) have been widely used by highway agencies. However, the cost of RWIS stations is high, and they have limited monitoring coverage. To address this challenge, this paper presents an innovative framework that applies regression kriging to integrate stationary and mobile RWIS data to improve the accuracy of road surface temperature (RST) estimation. Furthermore, an optimal RWIS network expansion strategy is introduced by incorporating a modified particle swarm optimization method with the objective of minimizing spatially averaged kriging estimation errors. A sensitivity analysis is also conducted to investigate the influence of station densities on model performance. The case study from Alberta, Canada, demonstrates the feasibility and applicability of the proposed method. The findings provide insights for continuous monitoring and visualization of both road weather and surface conditions and for optimizing RWIS network planning.

A major concern of drivers in winter is the current road condition. Taxis, which move ceaselessly around a wide area, have great potential as sensors for detecting road-surface conditions in a given area. To establish a method with which to estimate road conditions based on the vehicular motion of taxis, field experiments were conducted by using probe vehicles fitted with vehicular-motion sensors and a Global Positioning System device, before implementation in taxis. Preliminary analyses were performed by using data measured on a test track, urban streets, and an expressway. The slip ratio, defined as the relative difference in speed between vehicle and tire wheel, was effective in indicating how slippery the road surfaces were. Taxi vehicular-motion data were collected for more than 1 month, although unlike with probe vehicles, the wheel speed was not measured. Some features of vehicular motion specific to slippery roads were identified, and the discriminability of road conditions, whether icy or dry, without the use of wheel-speed data, was examined.

Abstract A numerical model designed to simulate the evolution of a snow layer on a road surface was forced by meteorological forecasts so as to assess its potential for use within an operational suite for road management in winter. The suite is intended for use throughout France, even in areas where no observations of surface conditions are available. It relies on short-term meteorological forecasts and long-term simulations of surface conditions using spatialized meteorological data to provide the initial conditions. The prediction of road surface conditions (road surface temperature and presence of snow on the road) was tested at an experimental site using data from a comprehensive experimental field campaign. The results were satisfactory, with detection of the majority of snow and negative road surface temperature events. The model was then extended to all of France with an 8-km grid resolution, using forcing data from a real-time meteorological analysis system. Many events with snow on the roads were simulated for the 2004/05 winter. Results for road surface temperature were checked against road station data from several highways, and results for the presence of snow on the road were checked against measurements from the Météo-France weather station network.
