Software Tools To Support Construction Practices
A few examples of software tools available to support sustainability of pavement construction operations are listed below.
CA4PRS is a software tool supporting the analysis of project alternatives for different pavement designs, construction logistics, and traffic operation options. It is designed to help highway agencies and contractors develop construction schedules to minimize traffic delay and reduce agency costs.
QuickZone is a software tool for traffic analysis that compares traffic impacts for work zone mitigation strategies and estimates traffic delays and cost.
Dynasmart-P is a dynamic traffic assignment analysis tool used in decision making for regional work zone management. It models the evolution of traffic flows resulting from travel decisions of the individual travelers. It can be used to evaluate traffic management strategies for highway construction projects, and can also help assess the impacts of intelligent transportation system (ITS) technologies.
A number of tools are available for use in analyzing GHG emissions on construction projects:
State Inventory Tool (SIT): This EPA's tool consists of eleven modules for applying top-down approach to calculate GHG emissions and provides an aggregated total for each sector (industrial, commercial, residential, and transportation) at the state level. Emissions for specific construction activities are not included.
NONROAD: This EPA's tool helps to estimate emission factors from all non-road vehicles (except locomotives, aircrafts, and commercial marines). This tool can differentiate equipment type and other characteristics and can be used to calculate emissions from specific construction activities.
MOVES: This is a comprehensive tool from the EPA for all on-road vehicles providing detailed reports on vehicle emissions. Vehicle operation characteristics, fuel type, geographic location, vehicle miles traveled, and other factors that may contribute to emissions are considered. However, since non-road vehicles are not considered, this model cannot be used alone to estimate construction related emissions.
(PE-2: This is a web-based pavement LCA tool applying a project based approach. The focus of the tool is estimating emissions associated with highway transportation projects over their life cycle, including production, construction, maintenance, and use phase. Web Link)
GreenDOT: This is an Excel-based greenhouse calculator from the operations, construction, and maintenance activities of state DOTs. It was developed under NCHRP Project 25-25 Task 58.
