Cycling Infrastructure Improvements: Active Routes Visualization (ARV) Tool

Many communities across the country seek to improve their livability, health, and economy by promoting more walking and bicycling.  One of the most successful ways to do this is by creating safe, enjoyable, and continuous routes through a community that connect people with their everyday destinations. 

The Active Routes Visualization (ARV) Tool is a flexible Python-based custom ArcGIS toolbox that uses community data to forecast potential active walking and bicycling travel demand between homes and everyday destinations to identify these active routes. The tool can be used by communities of any size, including rural and urban environments, and operates from readily available data for every community in the United States. The tool requires access to and a basic understanding of ArcGIS software.

The ARV Tool generates a planning-map that highlights the roadways and routes that would most likely support walking and biking between homes and everyday destinations in the community. This map is intended to be used by community coalitions, regional planners, and city engineers to identify routes that can be improved, promoted, and connected.  It is likely that coalitions may find that the routes suggested by the Tool accurately reflect the corridors where the community already walks or bikes.  It is equally likely that coalitions may find that the community prefers parallel routes to those suggested by the Tool, due to avoiding high vehicular volumes, busy crossings, or high conflicting speeds.  Both results are positive, as they provide decision-makers with data for selecting active routes to plan and promote.  The tool is meant to start data-driven discussions about the best ways to spend our time, energy and funds to support active routes to everyday destinations and ultimately improve our communities’ quality of life.

Quantifying Work Zone Impacts: Pavement Rehabilitation User & Business Cost Tool

Roadway maintenance and rehabilitation is a critical and ubiquitous activity for state, county, and city engineers across the country. With this task, engineers constantly identify effective and efficient scheduling and rehabilitation methods that offer the lowest impact on local users and businesses.

Asphalt concrete (AC) rehabilitation projects have the advantage of a fast turnaround project timeline which could reduce immediate residual economic costs to the surrounding area. These blanketing costs need to be considered in the pavement type selection process and construction scheduling which this report will attempt to cover. Past research regarding lifecycle cost analyses tends to focus a limited scope on construction related costs, while other sources and studies are currently out-of-date or over simplified . There are many factors affecting Road User Costs (RUCs), crash mitigation costs, and local business impact costs that need to be simultaneously accounted for in order to accurately calculate construction related cost values. Most importantly, no relevant data-driven work exists to quantify local business impacts of work zones beyond broad discussions about including local business owners in project planning.

The objective of this Tool is to provide a comprehensive set of data driven, nationally transferrable metrics that quantify the costs associated with asphalt and concrete pavement rehabilitation in terms of (a) road user costs, (b) crash mitigation costs, and (c) local business impact costs. Additionally, the Tool is able to show how these costs vary by (a) types of pavement rehabilitation, (b) surrounding development (urban vs rural), and (c) types of scheduling alternatives. Results are compiled into a convenient Excel tool for users to input project variables and receive associated direct and indirect costs. This tool is intended for any engineer or project manager who needs a streamlined, general analysis of likely impact costs when planning for road rehabilitation scenarios requiring lane closers. Users can test different scheduling alternatives to determine the least impactful course of action. Engineers and project managers can implement the models and tool developed in the project to a) characterize the road user, crash mitigation, and local business impacts of an existing project or projects that are being let for bid; b) to evaluate possible innovative scheduling opportunities in the project planning stage; and c) to illustrate to local business owners the potential loss in revenue they could receive during construction.
