Evaluation of performance across alternatives and modes is done through a series of manual worksheets by applying an approach based on five core areas including measures of mobility, agency cost, safety, user costs, and air quality. The evaluation can be limited to an analysis based on measures of effectiveness (MOE) or completed to include a measure of economic efficiency. To calculate the measures for each of the core areas, the analyst must describe the corridor or project to be analyzed, conceptualize the alternatives to be examined, collect baseline data pertinent to those alternatives and the chosen analysis framework, and aggregate the corridor into logical segments. For cases where some local data are unavailable, the guidebook includes a series of reference tables with default and average values for variables and parameters involved in the evaluation. After the MOEs under the baseline, No-build, and alternative conditions for each analysis year are summarized, the analyst can employ a multi-criteria ranking approach to select the best alternative action based on performance measures or perform an economic efficiency analysis173ocn154707723book20040.90Urban maglev technology development program Colorado maglev project, executive summary of final report162ocn043073992bks|url19990.88Shing, Pui-shum BCracking in bridge decks : causes and mitigationThis report summarizes the findings of a study whose primary objectives are to determine the cause of extensive transverse cracking that has been observed in some existing bridge decks, and to identify the change of material specifications and construction practice that is necessary to reduce the severity of deck cracking. To achieve these goals, recent studies on the cause of bridge deck cracking were reviewed, an experimental study was conducted to compare the shrinkage properties of different concrete mixes, and the current material and design specifications and construction practice adopted by the Colorado Department of Transportation (CDOT) were reviewed to identify areas that need improvement. A survey was conducted on seven newly constructed bridges to examine the extent of cracking in concrete decks that were constructed with the different mix designs and curing procedure that were currently used by CDOT163ocn048882108book20010.92Anderson, MikeForensic investigation of early cracking on I-25In May 2000 the Colorado Department of Transportation (CDOT) requested a forensic evaluation of a project located in I-25 north of Denver, Colorado. Within a year of the 1997 overlay, longitudinal cracking appeared in the surface. Two years later the pavement appeared to be deteriorating rapidly. In October 2000, a forensic team of pavement experts reviewed the project and established a sampling and testing plan. Based on the data analysis, it was the opinion of the forensic team that the early cracking of I-25 was caused by several factors, which were combined on this project. The factors included: higher in-place air voids than expected, and low effective asphalt and segregation within the mat202ocn043642759serial0.47ColoradoAnnual report184ocn048632780book20010.94Markow, Michael JAsset management implementation plan and tiered system processThis study has developed a five-year transportation asset management plan for the Colorado Department of Transportation (CDOT). This study has also developed a proposed tiering structure of the state highway system to support asset management. Asset management represents a strategic approach to managing transportation infrastructure. It embodies a set of principles to improve how an agency conducts business, how it reaches decisions, and how it processes, uses, and communicates information. CDOT, in consultation with the Colorado Transportation Commission, has already taken a number of steps toward improved asset management. A unique Investment Category approach organizes program investments within a policy-oriented framework incorporating explicit measures of performance. Other steps taken by CDOT include updates of the statewide planning process and the program prioritization process, establishment of maintenance program levels of service, institution of customer surveys, and updates of relevant information technology applications. The recommended transportation asset management plan builds upon these established concepts, methods, information, and tools to propose specific actions over the next five years in the following areas: (1) completion of all elements of the Investment Category structure; (2) incorporation of asset management principles in CDOT's planning and programming processes, building on a tiered structuring of CDOT assets that has also been recommended in this study; (3) integration of asset management information on a GIS platform, and renewal of Information Technology strategic planning to support asset management department-wide; and (4) strengthening of program delivery mechanisms and measures. The recommended tiering of the state highway system is built around the concept of interregional corridors, because CDOT is the sole provider of significant interregional highway transportation122ocn048854495book20001.00Epel, Joshua BEnvironmental liability studyThe study examines different mechanisms by which the Colorado Department of Transportation (CDOT) can either limit or avoid incurring cleanup costs and liabilities or, if that course is unavailable, recover those costs which must be incurred. The key to this approach is information, obtained as early in the acquisition process as possible. Accurate information about site conditions will allow CDOT to avoid severely contaminated properties, if possible, and to properly value those properties that must be acquired112ocn045212449book20001.00Long-range cost estimation research projectThe purpose of this project was to research long-range (parametric) cost estimation at the Colorado Department of Transportation (CDOT), utilizing AASHTO's Trns.port Cost Estimation and Decision Support software. Info Tech, Inc., analysis reviewed CDOT's current long-range estimation practices and identified revisions which would be needed to satisfactorily meet CDOT's future cost estimating requirements, i.e., in order to develop consistent and reliable cost estimates when little is known about a project. Both item and contract classifications utilized by CDOT in BAMS/DSS were revised to reflect more logical functional groupings. The new contract work type and item classification were used directly to develop an Interim Solution for Long-Range Cost Estimation that uses historical bid-based default prices. Info Tech analysts also researched Internet sources to identify the availability of major item cost data at the regional and national level, including data for multimodal project types112ocn503116152com0.27ColoradoAnnual transportation system performance report92ocn704931891com0.60ColoradoFinancial annual report for fiscal years ending93ocn186477676serial0.63ColoradoProposed budget for fiscal year92ocn704931418com0.88ColoradoAnnual report for fiscal year ending91ocn034024087serial0.73ColoradoOverview82ocn064665954book20060.47Chang, Nien-YinCDOT foundation design practice and LRFD strategic plan82ocn704909826com0.47ColoradoAnnual financial report for fiscal year ending72ocn707536728com0.30Transportation facts72ocn709895289com0.67ColoradoAffirmative action plan update72ocn647986138book20090.47Chinowsky, PaulWorker safety at the Colorado Department of TransportationThe Colorado Department of Transportation (CDOT) is currently investigating approaches to reduce the frequency and severity of work-related injuries.
