Road User and Mitigation Costs in Highway Pavement Projects
Author: David Leonard LewisPublisher: Transportation Research Board
ISBN: 9780309068222
Category : Business & Economics
Languages : en
Pages : 60
Book Description
This synthesis report will be of interest to transportation agency planners; design, construction, and maintenance engineers; and administrators, managers, economists, and other decisionmakers involved in programming highway pavement projects. This synthesis describes current practice with regard to road user and mitigation costs in highway pavement projects. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search of both domestic and foreign publications. This report of the Transportation Research Board provides detailed information on the various methods employed by transportation agencies to estimate user costs. The advantages and disadvantages of each are reported. Information on the various components of user costs (that is, time related, vehicle operating, safety, and environmental costs) is also included. In addition, the study reports on the various mitigation strategies available to agencies to reduce user costs. Information is also provided on how user costs and mitigation strategies have been applied to evaluate different alternatives; and how uncertainties, political considerations, and quality control contribute to the decisionmaking process.

Book Description
This paper was presented at the session titled 'Assessment of user costs in pavement infrastructure life-cycle costing'. In maintenance or rehabilitation of roadways, the road user cost can contribute significantly to the total life cycle cost. Road user costs have two major components: a) vehicle operating costs (VOC), which vary with surface roughness, vehicle type and other factors, and b) user delay costs, which vary with the length of work zone, duration of delay time, traffic volume, traffic handling strategy during rehabilitation, etc. This paper focuses of the delay cost component. A simplified model for estimating delay costs is presented. While a number of models have been developed for calculating user costs they require a large amount of input data. Moreover, they are cumbersome and time consuming to use with life cycle cost analysis (LCCA) spreadsheets. There are many situations where an approximate estimate of user delay costs is satisfactory. This estimate can be based on simplifying a more complex model. The complex model used herein was developed for the Ontario Pavement Analysis of Costs (OPAC) 2000 design methodology. This program is a comprehensive design package which includes life cycle cost calculations for different design alternatives including vehicle operating costs, user delay costs, etc. User delay occurs both during traffic slowing in approaching and/or proceeding through the work zone as well as due to queuing. The simplified model described in the paper is based on a large number of runs for OPAC 2000 for a representative set of conditions and various traffic handling strategies. These strategies range from a two-lane undivided facility with a flag-person to a multi-lane divided facility with different lane closure alternatives. The result is a series of simple look-up tables for each traffic handling strategy. Clearly illustrated is the exponetial increase in delay cost, which occurs when traffic volumes are high enough to cause queuing delay. Finally the paper presents life cycle analysis examples which illustrate the use of the simplified estimate of user delay costs. For the covering abstract of this conference see ITRD number E200883.
Gravel Roads

Book Description
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
