Qkan - Management Of Drainage System Data With Qgis, Jörg Höttges Sep 2017

Qkan - Management Of Drainage System Data With Qgis, Jörg Höttges

Free and Open Source Software for Geospatial (FOSS4G) Conference Proceedings

Based on QGIS a database structure and a set of plugins have been developed to improve the workflow for the hydraulic design of urban drainage systems for consulting engineers. The main goal is pre- and postprocessing in combination with various commercial hydraulic simulation software packages. The plugins provide import and export functionalities, simulation result viewing and generation of longitudinal cross sections in a CAD program. All modules make intensive use of SQL based spatial functions instead of functions implemented in QGIS, because of their stability, higher flexibility and speed due to the indexing functionality. On the other hand the database …


The Feasibility Of Road User Fees And Other Alternative Sources Of Transportation Funding, Joshua R. Amberg Jul 2017

The Feasibility Of Road User Fees And Other Alternative Sources Of Transportation Funding, Joshua R. Amberg

Pepperdine Policy Review

The nation faces an approaching crisis in transportation funding. This is a critical issue that is both relevant and essential to public administration. It affects all levels of government and extends across the nation. Rapidly declining sources of transportation funding pose short-term and long-term challenges for politicians, public administrators, and everyday citizens. In the face of inadequate revenues, new forms of funding are necessary to keep the transportation system solvent. This paper will briefly outline the history of transportation funding that created this problem and examine various proposed solutions. It will focus specifically on the emerging theory of road user …


The Epa's Air Quality Index, And Public Transportation Usage In The Chicago Metro Region, Nicholas R. Rosenberg Jul 2017

The Epa's Air Quality Index, And Public Transportation Usage In The Chicago Metro Region, Nicholas R. Rosenberg

Journal of Environmental and Resource Economics at Colby

This paper assesses whether air quality influences public transportation ridership in the city of Chicago. Urban air pollution is a serious health risk, and a priority of urban municipalities. Public transportation is an attractive option for governments attempting to curb urban air emissions. I use data from the Chicago Transit Authority (CTA) and the EPA’s Air Quality Index (AQI) to explore the relationship between a day’s air quality and CTA ridership. I employ three different model specifications, rail, bus and total ridership, to test whether high AQI values (poor air quality) result in increased public transportation ridership in the city …


Ticket To The Past: A Political History Of The Mexico City Metro, 1958-1969, Maxwell E.P. Ulin May 2017

Ticket To The Past: A Political History Of The Mexico City Metro, 1958-1969, Maxwell E.P. Ulin

Grand Valley Journal of History

This essay outlines the historic political battle between Mexico's longest serving mayor, Ernesto Uruchurtu, and the nation's president, Gustavo Diaz Ordaz, over the construction of what would become the second largest subway system in the Western Hemisphere, The Mexico City Metro. The conflict, which eventually resulted in Uruchurtu's resignation, was characterized by latent political tensions between the PRI and Mexican middle class that would erupt in 1968 and lead to the ultimate decline of PRI hegemony. I thus argue that the new Metro project did not reflect Mexico's democratic modernization--as its supporters meant it to do--but rather the vestiges of …


A Framework For Measuring The Spatial Equity In The Distribution Of Public Transportation Benefits, Seyyed Amir Hosein Mortazavi, Meisam Akbarzadeh Mar 2017

A Framework For Measuring The Spatial Equity In The Distribution Of Public Transportation Benefits, Seyyed Amir Hosein Mortazavi, Meisam Akbarzadeh

Journal of Public Transportation

This paper proposes that an equitable transit system requires that the geographical distribution of transit service benefits conform to the geographical distribution of the citizens with the greatest need for public transportation. This is the essence of vertical equity. This study calculated “connectivity power,” which reflects public transit service quality in each traffic analysis zone (TAZ) in a city to indicate the amount of benefit that TAZ is receiving from the transit system. The number of carless citizens in each TAZ was also calculated as an index of need to the public transit services in that area. Conformity of need …


The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens Mar 2017

The Causal Effect Of Bus Rapid Transit On Changes In Transit Ridership, Orion T. Stewart, Anne Vernez Moudon, Brian E. Saelens

Journal of Public Transportation

Numerous studies have reported ridership increases along routes when Bus rapid transit (BRT) replaces conventional bus service, but these increases could be due simply to broader temporal trends in transit ridership. To address this limitation, we compared changes in ridership among routes where BRT was implemented to routes where BRT was planned or already existed in King County, Washington. Ridership was measured at 2010, 2013, and 2014. Ridership increased by 35% along routes where BRT was implemented from 2010 to 2013 compared to routes that maintained conventional bus service. Ridership increased by 29% along routes where BRT was implemented from …


A Refuge For Refugees: The Historical Context And Socioeconomic Impact Of Palestinian Refugees In Jordan, Amelia Marie Dal Pra Jan 2017

A Refuge For Refugees: The Historical Context And Socioeconomic Impact Of Palestinian Refugees In Jordan, Amelia Marie Dal Pra

Global Tides

Today more than 41 percent of the Jordanian population is comprised of Palestinian refugees. Some argue that Jordan has become the new Palestinian state in place of their former land pre-1948. This paper presents the complications of this claim by focusing on the Jordanian government’s constitutional provisions on refugee citizenship, Palestinian support programs and the role the Palestinian identity has played in the integration, or lack thereof, of Palestinian refugees into the social, political, and economic spheres of Jordanian society.
