Development of a Pavement Quality Index for the State of Ohio
Every agency responsible for the maintenance of roadway systems faces the problem of insufficient funding to perform all of the necessary repairs on pavement sections. Therefore, highway agencies must adopt a pavement management system (PMS) to help set priorities. The PMS includes a method for evaluating pavement performance on a routine basis and identifying sections with a need for rehabilitation or maintenance. Some states in the U.S. use a pavement rating system that is based solely on visible surface distresses, while others use an index based on ride quality alone to perform the regular evaluation of pavements and to select projects. Increasingly, many states are using a combination of distress and ride quality. The Ohio Department of Transportation (ODOT) utilizes the Pavement Condition Rating (PCR), based on surface distress, for project selection. This paper outlines the development of a new performance index for pavements that incorporates aspects of ride quality together with surface distress for possible adoption by ODOT. The proposed index is called the Pavement Quality Index (PQI). The PQI does not require any new measurements or methods; rather, it simply utilizes procedures that are already in place and well established in Ohio. The PQI is an amalgam of the PCR and the International Roughness Index (IRI). The development of the new index is the natural extension of the growing trend that transportation agencies are placing increased emphasis on customer satisfaction, and also introducing performance-based specifications

Success factors of project and process management — lessons learned from EPPM 2016
The aim of this post-conference report is to present
key-issues delivered by participants of the Project
and Process Management sessions (PPM) at the 7th
International Conference on Engineering, Project,
and Production Management (EPPM 2016). EPPM
2016 was held in Bialystok, Poland in 21-23 September. The format of the EPPM 2016 Conference involved a mixture of keynote speeches, individual presentations
on topical issues, and extensive panel discussions.
It featured 89 papers in five thematic sessions
across the two conference days. Over 115 delegates
attended EPPM 2016 from more than 20 countries
across Europe, Asia, and the rest of the world
Data monitoring of friction value tests on a high seasonality runway
The friction value of runway and taxiway pavements is one of the indicators used in combined with others for implementation of airport pavement management system. The knowledge of its performance provides support for safety runway operations and maintenance strategies. This research illustrates the results obtained analyzing friction data performed in the last ten years at a high seasonality airport. The data survey was carried out on a monthly base and analyzed with the scope of understanding the decay trend in regard to aircraft movement number, weather conditions and pavement maintenance. A general descending trend, strict-ly connected with pavement maintenance, was obtained. Oscillatory values were observed in the annual term, indicating the influence of seasonal traffic and weather conditions on runway wearing course performance. The obtained results can support pavement managers in scheduling routine maintenance and identifying funds needed
COST-BASED ANALYSIS FOR HIGH SEVERITY LOCATIONS OF TRAFFIC ACCIDENTS IN JORDAN
Traffic accidents constitute a serious cause of death and injuries in the entire world. They are also considered as a major cause of financial and physical losses. This causes traffic accidents to have considerable threats and negative impacts on the entire society.
In the past few years, a large growth in the mobility of vehicles in Jordan has contributed to an increase in traffic congestion as well as in the number of traffic accidents. Although previous studies have indicated that risky behavioral characteristics of drivers is the main reason behind traffic accidents in Jordan, the number and severity of accidents can be mitigated and road safety can be improved through better design and engineering of road systems.
This study aims at investigating and analyzing traffic areas in the Governorate of Madaba in Jordan that can be considered as having low level of safety and so causing major negative impact on people’s health and emotions. Data that shows severity, location and number of people and vehicles involved in each traffic accident in Madaba Governorate for the period from 2011 until 2013 was collected from the databases of the Pubic Security Department (PSD) in Jordan and analyzed.
Since the identification of accident location is a critical element in accidents’ analysis, accidents were located on road maps. Sites with large number of accidents were precisely investigated and studied in terms of the severity of accidents, the expected economic loss and the problems causing the accidents in these sites.
This study will produce a number of practical solutions aim at improving the traffic safety and reducing the frequency and severity of traffic accidents and the associated economic and social costs in the governorate. This research will constitute a model for further studies that can be conducted in other areas in Jordan and in the world
Pavement Deterioration Rate and Maintenance Cost for Low-Volume Roads
Allocated budgets for maintenance of road networks are normally limited. Therefore, not all roads receive the required attention they deserve in a timely manner. These roads are left to deteriorate until the next maintenance round. The cost associated with delayed maintenance is significantly excessive. A Pavement Maintenance Management System (PMMS) can be a useful tool for evaluation, prioritization of Maintenance and Rehabilitation (M&R) projects, and determination of funding requirements and allocations. The pavement condition is normally indexed using a parameter called Pavement Condition Index (PCI) which represents an overall assessment of surface defects by type, severity and extent. Periodic collections of PCI over time for different sections within the roadway network provide an approach to monitor changes in pavement serviceability over time and can produce useful data to predict and evaluate required maintenance solutions and their associated cost. The researchers intend to use available data collected over the span of a year and a half on sections within the roadway network at the campus of Al-Zaytoonah University of Jordan (ZUJ) to study the relation between the maintenance cost and the pavement deterioration rate. This study may incorporate variables such as pavement age, traffic volumes, maintenance history and pavement condition assessment results. The available records of PCI will be analyzed and the findings will be clearly presented. The practical inclusion of the findings within the current PMMS used at the university will also be detailed
