The Cost

The roadway infrastructure constantly deteriorates because of environmental conditions, but other factors such as exposure to heavy trucks exacerbates the rate of deterioration. Therefore, decision-makers are constantly searching for ways to optimize allocation of the limited funds for repair, maintenance, and rehabilitation of New Jersey’s infrastructure. New Jersey legislation requires operators of overweight (OW) trucks to obtain a permit to use the infrastructure. The New Jersey Department of Transportation (NJDOT) issues a variety of permits based on the types of goods carried. These permits allow OW trucks to use the infrastructure either for a single trip or for multiple trips. Therefore, one major concern is whether the permit revenue of the agency can recoup the actual cost of damage to the infrastructure caused by these OW trucks. This study investigates whether NJDOT’s current permit fee program can collect enough revenue to meet the actual cost of damage to the infrastructure caused by these heavy-weight permit trucks. The infrastructure damage is estimated by using pavement and bridge deterioration models and New Jersey permit data from 2013 to 2018 containing vehicle configuration and vehicle route. The analysis indicates that although the cost of infrastructure damage can be recovered for certain permit types, there is room for improvement in the permit program. Moreover, based on permit rules in other states, the overall rank of the New Jersey permit program is evaluated and possible revisions are recommended for future permit policies.

The roadside Inspection Selection System (ISS) was developed in response to a 1995 congressional mandate that called for the use of prior carrier safety data to guide the selection of commercial vehicles and drivers for roadside inspections. The program was developed in part by the Federal Motor Carrier Safety Administration (FMCSA) of the U.S. Department of Transportation. As ISS has developed, FMCSA’s Performance and Registration Information Systems Management (PRISM) program has also been evolving. One objective of PRISM is to identify relatively unsafe carriers by assigning Safety Status Measurement System (SafeStat) scores and also encouraging those drivers to improve their safety performance or risk losing registration privileges. SafeStat was designed to prioritize carriers for monitoring and compliance reviews, but ISS was designed to prioritize carriers for roadside inspection. Both algorithms, however, use similar data to define a relatively unsafe carrier. It would be advantageous therefore to have a single uniform rating system for all FMCSA programs. This research briefly describes the PRISM and SafeStar algorithms; discusses the integration of the SafeStat algorithm into ISS; and presents conclusions on the initial testing of the resulting system, ISS-2. An analysis of over 213,000 roadside inspections reveals that ISS-2 is as effective as the original ISS in meeting the goals for which it was designed. It successfully identifies and prioritizes for roadside inspection the vehicles and drivers of carriers with poor prior safety performance, as well as those with few or no previous inspections. In addition, safety inspectors who have tested the system say they are pleased with the new algorithm and its added features.

Performance mix design (PMD) of asphalt mixtures, often referred to as balanced mix design, is a design methodology that incorporates performance testing into the mix design process. The Virginia Department of Transportation (DOT), like many owner agencies, is interested in ways to specify asphalt mix designs better in an effort to make its roadway network more sustainable, longer lasting, and more economical. By adding performance criteria through a PMD framework, that goal can be achieved. Further, a PMD framework should allow for the development of new, innovative methods to increase pavement recyclability, new performance additives, and other means to enhance pavement performance. This paper provides details and documentation of the approach being taken by the Virginia DOT in their efforts to develop a PMD specification. Aspects of development presented include PMD method options, selection of performance tests, and determination of acceptance criteria. A discussion about validating specifications with in-service performance data and addressing quality control and quality assurance is also provided. Although additional work is needed for full development and implementation, the methodology being applied has been found to provide useful outcomes for the Virginia DOT even in the initial stages of development.

The use of Alternative Technical Concepts (ATC) is becoming widespread in design-build transportation projects in the United States. According to Federal Highway Administration (FHWA) ATC is a request by a proposer (usually in design-build projects) to modify a contract requirement for gaining competitive advantage over competition. The owner, usually a state department of transportation, requires that the ATC provide a better or at least equal solution to the owner’s design requirements. In Design-Build (DB) projects, the ATC is usually proposed by a proposer during the Request for Proposal (RFP) process and is considered in the evaluation and selection of the proposers in conjunction with the Best Value (BV) method of selection. In this paper, the authors have focused on two case studies involving ATC implementation and negotiations with the Massachusetts Department of Transportation (MassDOT) highlighting advantages and disadvantages of using ATC in DB contracts. In each case, the nature of ATC and the approval process is discussed. In the first case, the approved ATCs provided the proposer with a clear advantage in winning a contract with the agency despite not being the low bidder. In the second case, the proposed and approved ATCs did not result in winning a contract despite being the low bidder.

The Florida Department of Transportation is in the process of developing a statistically estimated model of pedestrian quality of service for midblock street crossings as part of its Multimodal Quality of Service Program. This model is to be used in evaluating the level of service of street segments for pedestrian street crossing. The actual development of the model, including methodological issues explored, data collection, and model calibration and validation, is reported separately. A process was used to select potential determinants of perceived pedestrian quality of service for midblock street crossings. This process is structured and involves two steps. The first step involves the selection of a set of potential determinants through a theoretical analysis of pedestrian behavior for street crossing. The theoretical consideration ensures that these potential determinants have a sound behavioral foundation. The second step involves narrowing down this theoretical set through a practical analysis of planning needs and data requirements by an advisory committee. This practical consideration ensures that the final set of potential determinants and the model both are practically relevant.

Through its National Center for Transit Research, and under contract with the Florida Department of Transportation, the Center for Urban Transportation Research (CUTR) was tasked with reviewing a sample of data on transit bus crash occurrence from selected Florida transit systems. The purpose of this review is to analyze changes in crash occurrence over time in relation to the effectiveness of training programs and capital safety improvements in reducing bus crashes. To this end, CUTR conducted two case studies utilizing occurrence data from Hillsborough Area Regional Transit Authority in Tampa (which implemented a refresher training course for bus operators) and LYNX Transit in Orlando (which replaced standard rear-end brake lights and turn signal and emergency flasher lights with high-density LED lights). The case studies examined the effect that these two particular safety campaigns had on postimple-mentation bus crash occurrence for the two properties. In addition to the promotion of safety, it is anticipated that this effort will be a preliminary step in the process of establishing a general list of safety campaigns, along with related costs and “rule of thumb” occurrence prevention effectiveness levels for each. A list of this nature will aid transit systems in Florida, the United States, and elsewhere in the selection of safety campaigns that will meet financial and safety goals.

The Ohio Department of Transportation (ODOT) constructed a test pavement on US-23 in Delaware County, Ohio. Of the nine Specific Pavement Studies (SPS) formulated by the Strategic Highway Research Program (SHRP), four (SPS-1, SPS-2, SPS-8, and SPS-9) were included at the OH-SHRP DEL-23 site. Sensors were carefully selected and installed to monitor structural response and seasonal parameters on the basis of prior field experiences accumulated in the United States and Canada. Criteria used to select the sensors were cost, accuracy, sensitivity, longevity, and level of success in previous pavement research projects, especially projects in Ohio. Described here is the development of the Ohio test pavement in terms of objectives, overall instrumentation plan, and selection of sensors as well as typical instrumentation plans for asphalt concrete and portland cement concrete sections.

This research entitled Analysis of Planning and Budgeting Conceptency in Pegunungan Bintang District Case Study On Department of Transportation, Communication and Informatics Year 2013-2015. In this research try to analyze consistency between planning and budgeting seen from planning and budgeting document like RKPD, PPAS, and APBD. RKPD (Local Government Work Plan), which is the result of the selection of community aspirations through the Development Planning Council (Musrenbang). Furthermore, RKPD work plan and funding are used as guidance in the budgeting process (budgeting). Budgeting begins with the preparation of Temporary Budget Priorities and Ceiling (PPAS). The approved PPAS is used as a guideline for the preparation of Regional Revenue and Expenditure Budget Plans (RAPBD) which is then ratified into Regional Revenue and Expenditure Budget (APBD). The results of the analysis are then analyzed using the Planning and Budgeting Consolidation Matrix to see how far the consistency is occurring. The results of this study indicate that the average level of consistency planning and budgeting in the field of Transportation, Communications and Informatics in Pegunungan Bintang District in 2013-2015 is quite good where the average level of consistency of programs between RKPD and PPAS ranges between 80.00%. While the average level of consistency of activities is 61.98%. This indicates that the drafting of the plan on PPAS still exists that is not guided by RKPD. The level of program consistency between PPAS and APBD has an average value of 60.64%. While the average level of consistency of activity is 63.19%. The level of planning and budgeting concessions from year to year shows a fluctuating value. In consistency the budget outline has a consistent value. Inconsistencies occur because there are activities that suddenly appear and are not contained in the previous document. This is due to delays in information activities from the central government.
