Investigation Of Crashes And Identifying The Best Practices For Setting Up Speed Zones In Towns Along Rural Highways In Nevada, Krishna Prasad Shrestha

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2010, 51,664 crashes occurred in Nevada. Only about 9% of those crashes occurred in rural areas of the state. However, if only fatal crashes are considered, 41% of those fatal crashes occurred in rural areas. Generally, speed zones are provided in towns along rural highways to reduce speed-related crashes. However, a guideline is necessary for a consistent procedure to setup speed zones throughout the state. The main objectives of this study are to determine factors associated with crashes and to identify the best practices for setting up speed zones in towns along rural highways.

Eleven towns along rural highways …

Statistical Analysis Of A Vehicle Miles Travled Fee For Nevada, Andrew Nordland

UNLV Theses, Dissertations, Professional Papers, and Capstones

Increases in the number of electric, hybrid-electric, and other alternative fuel vehicles, combined with increasing vehicle fuel efficiency present problems with the ability of the fuel tax to collect sufficient revenue. A Vehicle Miles Traveled (VMT) Fee is being considered as an option to replace the existing fuel tax for the collection of revenue for road maintenance, reconstruction and expansion. This study provides an analysis about costs, preference of a potential billing cycle, level of comfort with a mileage collection device, potential changes in transit use, and the effectiveness of a VMT Fee for Nevada. Multinomial logit models are developed …

Quantity-Based Cost Forecasting System For Street Construction Projects, Nipesh Pradhananga

UNLV Theses, Dissertations, Professional Papers, and Capstones

Construction projects typically are not withdrawn after going into the competitive bidding process. The decision of contracting authorities regarding which projects will proceed to the bidding stage depends, in part, upon the early estimates of probable cost. Efforts are made to make this estimate as realistic as possible. Irrespective of the estimate of probable cost, the actual project cost is established by the amount of the winning bid.

This study analyzed historical bid data of street construction projects undertaken by the Public Works Department, Clark County, Nevada, from 1991 through 2006. The focus of this study was on utilizing statistical …
