Getting from A to B is not as easy these days. Time, energy, economics, efficiency can be critical factors when moving people, services and commodities. Learn more about routing strategies for getting what you need, where you want.
- Using NPMRDS Travel Time Data for Evaluating Roadway Congestion
John Wisdom
The recently available National Performance Management Research Data Set (NPMRDS) provides transportation agencies with access to detailed travel time data which can be used to generate meaningful information on mobility and congestion. This presentation will discuss how these data can be analyzed with GIS to evaluate congestion, identify bottlenecks and generate other performance measures. Methodology and issues encountered when working with the data will also be covered.
- GIS-Based Sanitation Route Optimization
Scott Barnwell
In an effort to streamline operations and reduce costs, the City of Asheville embarked on an effort to optimize and balance sanitation truck routes. After an extensive data cleanup effort and field data collection, city staff modeled sanitation collection routes and determined the variables that impact route efficiency. Applying the model led to significant reductions in time and cost to collect solid waste in Asheville.
- Creating Routable Railroad GIS Layers for North Carolina with the NCDOT Rail Division
Dwight Otwell
Government organizations, international transportation corporations and design and development industries rely on accurate transportation network modeling to guide decision making. Such models require comprehensive and accurate dataset. North Carolina DOT has long maintained high-quality GIS data describing state and local street networks, available for public and internal use. Until recently, North Carolina did not offer comparable railroad layers, and what is available in the form of Tiger and Federal Railroad Administration data is incomplete and inaccurate.
NCDOT Rail Division partnered with Moffatt & Nichol Engineers to develop an authoritative collection of GIS layers to describe track, crossings and transload facilities. The dataset contains all public and pedestrian crossings in the state and topologically connected linework representing all active track in North Carolina. Moffatt & Nichol continues to provide quarterly updates to this resource.
We propose that Senior Data Analyst Dwight Otwell, GISP of Moffatt & Nichol present a narrative detailing the creation of this dataset, focusing on the importance of an accurate, routable network to support transportation planning and economic modeling vital to government and private interests. Mr. Otwell will explain the complex and conflicting source data and explain how Moffatt & Nichol's workflow takes advantage of many combined decades of experience in the rail industry to resolve these conflicts.
