A Simple Method For Estimation Of Queue Length, S. P. Anusha, Lelitha Devi Vanajakshi, Anuj Sharma Dec 2013

A Simple Method For Estimation Of Queue Length, S. P. Anusha, Lelitha Devi Vanajakshi, Anuj Sharma

Department of Civil and Environmental Engineering: Faculty Publications

Urban arterials are characterized by frequent intersections. Queue length and delay are the two primary measures of performance of intersection. These measures play a primary role in determining the arterial performance. This article presents a methodology to determine the number of vehicles in queue at a signalized intersection for under saturated traffic conditions. The results obtained were validated using actual values that are manually extracted. The root-mean-square error is of the range 1.3 vehicles for estimation of number of vehicles in queue. The various aspects that have to be considered in accurate estimation of performance measures are also discussed.


Segregation, Inequality, Demographic Change, And School Consolidation, William England, Edmund T. Hamann Dec 2013

Segregation, Inequality, Demographic Change, And School Consolidation, William England, Edmund T. Hamann

Great Plains Research: A Journal of Natural and Social Sciences

We describe a rural/micropolitan example of the intertwining of school consolidation and demographic change with exacerbated segregation and inequality. To do this we consider Dawson County, Nebraska, which hosts the state's most Latino/a school district (Lexington) and which saw its number of schools decline from 37 to 19 during this century's first decade, and the number of local school districts lessened from 18 to 5. In particular, we call attention to the irony that consolidation was pursued with an explicit call for more equality in schooling in Dawson County (Swidler 2013) and yet population concentrations and variation in expenditures seemed …


The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi Sep 2013

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …


Factors Affecting Students Walking To School: Case Study Of Two Middle Schools In Lincoln, Nebraska, Nivin S. Khalil May 2013

Factors Affecting Students Walking To School: Case Study Of Two Middle Schools In Lincoln, Nebraska, Nivin S. Khalil

Community and Regional Planning Program: Theses and Student Projects

Physical activity, including walking, can be a very healthy and sustainable mode of transportation. Children walking to their schools can get a lot of benefits from acquiring good habits that can be carried through their adulthood. Also, walking to school can reverse the trend of increasing obesity rates among children in the United States. This study is trying to identify the effect of urban form, presented in the distances between residences and schools, on the children’s behavior whether they walk to school or not depending on different urban forms around their schools. Two middle schools in Lincoln, Nebraska were selected …


The Legislative Purposes And Intent Of The Common Levy In Nebraska’S Learning Community, Matthew L. Blomstedt May 2013

The Legislative Purposes And Intent Of The Common Levy In Nebraska’S Learning Community, Matthew L. Blomstedt

Department of Educational Administration: Dissertations, Theses, and Student Research

The purpose of this historical study was to establish the purposes and intent of the common levy in Nebraska’s learning community. The development of this unique regional educational structure consisting of eleven school districts in the Omaha, Nebraska metropolitan area is central to the study. The research detailed the context of the decisions made by the Nebraska Legislature to establish and implement the learning community law from 2005 and 2012. Specifically, the study focused on the establishment of a regional tax base, the common levy, as a response to boundary and finance instability that persisted in the Omaha area. The …


From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto Jan 2013

From Mounds To Maps To Models: Visualizing Ancient Architecture Across Landscapes, Heather Richards-Rissetto

Department of Anthropology: Faculty Publications

Since the onset of settlement pattern studies in the 1950s, landscape mapping projects have become an archaeological mainstay. Remote sensing technologies such as lidar, photogrammetry, and SAR (Synthetic Aperture Radar) steadily reveal new archaeological sites. For landscape archaeology, the detection and mapping of small architectural complexes and households offers important data to contextualize larger (often already known) sites and perform regional analyses. However, because the majority of sites remain unexcavated, analysis is limited, and yet Geographic Information Systems (GIS) and 3D Visualization are expanding the possible uses for older and newly-acquired data on unexcavated mounds. This paper describes a GIS …
