Comprehensive Framework For Speed-Zone Guidelines, Joseph Shrestha, Pramen P. Shrestha Jul 2016

Comprehensive Framework For Speed-Zone Guidelines, Joseph Shrestha, Pramen P. Shrestha

Joseph Shrestha

Speeding is often considered as one of the major reasons of traffic crashes. As a result, State Departments of Transportations (DOTs) receive requests from communities to decrease speed limits in towns along rural highways. Such requests, coupled with the lack of proper manuals, have forced state DOTs to reduce the speed limits. A proper speed-zone manual is required to establish consistent speed zones across a state. This paper reviewed the literature on speed, crashes, enforcement techniques, and speed-zone manuals. A nationwide survey was conducted to identify various factors affecting the decisions of speed zones establishing. This paper identified best practices …

Using Web Scraping Technology To Automatize Cost Data Collection For Calculating Construction Cost Indexes, Joseph Shrestha, H. David Jeong Dec 2013

Using Web Scraping Technology To Automatize Cost Data Collection For Calculating Construction Cost Indexes, Joseph Shrestha, H. David Jeong

Joseph Shrestha

Construction Cost Index (CCI) and Building Cost Index (BCI) published by Engineering News Record (ENR) are two of the very popular cost indexes used in the industry. Many state DOTs publishes their highway construction cost indexes to keep track of the current trend of cost escalation. The ENR BCI and ENR CCI are prepared by collecting cost data from agents of the 20 cities in the country. Such manual process of collecting cost data can be costly. The proposed method of price data collection, based on a computer technology called “web scraping,” can automatically collect material prices and labor wage …

Dwr Based As-Built Schedule –Powerful But Highly Neglected Application Of Dwr Data, Joseph Shrestha, H. David Jeong Dec 2013

Dwr Based As-Built Schedule –Powerful But Highly Neglected Application Of Dwr Data, Joseph Shrestha, H. David Jeong

Joseph Shrestha

Daily work report (DWR) is a very important data recorded by the inspectors during the construction projects. Although, a lot of time and effort is invested to collect this big amount of DWR data, its use has been limited mostly to the contractor payment and dispute resolution. This study presents the methodological details about utilizing the historical DWR data to automatically generate the schedule for future projects based on the bid data. As a proof of concept of concept, as-built schedules has been developed from the DWR data. The as-built schedule generated can be used as a tool for more …

Big Data, Predictive Analytics, And Data Visualization In The Construction Engineering, Joseph Shrestha Dec 2013

Big Data, Predictive Analytics, And Data Visualization In The Construction Engineering, Joseph Shrestha

Joseph Shrestha

The term “big data” is associated with one or more of the four characteristics: volume, variety, and velocity. The technologies associated with the big data has already been proven in other sectors. Internet giants like Google, Facebook, Netflix, etc. uses big data collected from their users to present advertisements, friend recommendations, and TV shows and movies relevant to the specific user. Big data is also used for insurance fraud detection, improving bus system by reducing congestion, predictive flight arrival time, weather forecast, and genomic analysis.
For the construction industry, volume and variety becomes particularly relevant. From project planning to the …

Investigation Of Crashes And Identifying The Best Practices For Setting Up Speed Zones In Towns Along Rural Highways In Nevada, Krishna Prasad Shrestha Nov 2013

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

Joseph Shrestha

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 …
