Quantifying Road User Costs with Heterogeneous Value of Motorists' Travel Time
… zone impact assessment requires calculating road user costs (RUCs) which is the sum of vehicle operating costs, accident costs, and value of time (VOT). The term ?value of time? refers to monetary equivalent of travel time wasted due to rehabilitation projects. In current practice, STAs assume VOT …

El Serafy User costs and their implications for macroeconomic policy in Africa's mineral rich economies
… resource rent management given the El Serafy User cost approach. The study estimates the budget deficit and national debt as a proportion of net national product adjusted for mineral resource depletion in each country and evaluates the outcome by comparison with standard ‘rules of thumb’ …

Effect of pavement surface properties on life cycle cost analysis
… project. The two main pillars of LCCA are user costs and agency costs. User costs are incurred during normal transportation operation and when there is a work zone present. Costs that occur during normal operating conditions are due to pavement surface profile, while costs that occur during …

Economic evaluation of toll plaza operations
… These variables are then utilized to evaluate user costs and toxic gases emitted in toll plazas. A large amount of information on highway user costs was collected and synthesized to be incorporated in this economic evaluation. Recommendations on the amount of toll that should be charged to take …

Development of a User Cost Estimation Procedure for Work Zones.
… and queues are formed, thus causing increased costs as a result of the additional time and fuel needed to traverse the work zone. These user costs can be estimated and applied as a form of incentive to the contractor to complete the work sooner, thus allowing traffic to return to the free-flow …

Design of long span modular bridges for traffic detours
… schemes which can have variable impact on user costs. Detouring traffic with a modular bridge proved to be the most desirable scheme in terms of user costs such as traffic delays, detour distances, ultimate highway geometrics, construction crew safety, and safety of drivers. Criteria that …

Intermodal transit system coordination with dynamic vehicle dispatching
… total cost function, including supplier and user costs, are formulated for optimizing the coordination of a general intermodal. transit network. A four-stage procedure is developed for determining the optimal coordination status among routes at every transfer station. Considering stochastic …

Pavement management analysis of Hamilton County using HDM-4 and HPMA
… estimate fuel consumption; calculate road agency costs and user costs; determine cost-effective maintenance treatment; and suggest optimum utilization of funds. From this study, fuel consumption is higher at peak hours due to reduced traffic speeds. User cost is higher on the state route than the …

A Methodology to Determine Non-Fixed Performance Based Thresholds for Infrastructure Rehabilitation Scheduling
… maker, the relative weight of agency and user costs, and the form of expression of the life-cycle cost associated with the candidate rehabilitation schedules. Fortunately, a number of past researchers have developed inputs that are valuable for addressing this issue. Also, there exists …

A PROJECT-LEVEL INFRASTRUCTURE MANAGEMENT FRAMEWORK FOR SUSTAINABLE ROADWAYS
… experienced severe deterioration, costing road users billions of dollars in wasted fuels, lost time, and higher numbers of accidents. Transportation infrastructure asset management initiatives, which aim at providing and maintaining physical infrastructure assets at an acceptable level, need to …

Effectivess of Using Geotextiles in Flexible Pavements: Life-Cycle Cost Analysis
… cost analysis (LCCA), which includes not only costs to agencies but also costs to users, is urgently needed to assess the benefits of using geotextile in secondary road flexible pavement. In this study, a comprehensive life cycle cost analysis framework was developed and used to quantify the …

A Study of the Effectiveness of Unmanned Radar as a Speed Control Technique in Freeway Work Zones
… among speed control conditions in work zones. User costs associated with work zones were also examined. At the sites studied, significant reductions in mean speed and in percent of traffic exceeding the speed limit were observed, as were minor reductions in speed variance and eighty-fifth …

Life cycle cost analysis of asphalt and concrete pavements
… period. Construction, rehabilitation and user costs are included in the model. A 6% discount rate is used for the base case scenario, and the allowed rut depth is 3.5 cm. As was to be expected, a flexible pavement is more suitable for lower volumes of traffic, and with increased traffic, …

Satellite Rural Telephone Network Design: A Methodology for Performance Optimization
… It is generally considered that rural telephone users do not generate the same level of telephone traffic and, thus, revenue as urban users, lowering the incentives to invest in rural telecommunications. The financial implications of wiring a vast area for low telephone traffic causes most …

Guideline for Implementing Accelerated Bridge Construction in South Dakota
… Less interruption to traffic also lowers agency costs associated with traffic control and road user costs from delays and detours. The main objective of this study was to implement a systematic method for evaluating ABC techniques to determine their applicability to bridge construction and …

A Review of Road User Cost Methods and Methodology
… designed to review state-of-the-practice road user cost (RUC) calculations, evaluate current SDDOT methodology, propose improvements and implement them in a new analysis worksheet for use by SDDOT. This report includes an extensive literature review and the results of targeted surveys for …

Methodology for Development of Delay-Based Passenger Car Equivalents of Heavy Vehicles in Work Zones
… A new methodology is proposed to compute user delay and user costs in work zones. Unlike previous methodologies, the effect of differences in speeds within and between vehicle types is considered. The D_PCE values developed in this research are used to compute moving delay and input-output …
