Hampton Roads 2045 Long-Range Transportation Plan: Spatial Analysis of Candidate Projects

Hampton Roads 2045 Long-Range Transportation Plan: Spatial Analysis of Candidate Projects

The Long-Range Transportation Plan (LRTP) serves as the blueprint for the region’s transportation system, identifying all regionally-significant transportation projects for the Hampton Roads metropolitan area.  LRTPs have planning horizons of at least twenty years and are updated regularly in order to reflect changing conditions and priorities.  The current LRTP for Hampton Roads has a planning horizon of 2040, and is being updated to the year 2045.

A major component of the LRTP update process includes identifying projects that help achieve the region’s vision for the transportation system.  For the 2045 LRTP, HRTPO staff collected over 300 candidate projects from regional stakeholders.  These candidate projects will be evaluated using the HRTPO Project Prioritization Tool- a tool that evaluates projects based on technical merits and regional benefits, helping regional decision-makers in selecting the best projects for the 2045 LRTP.

Spatial Overlay Analysis

As part of project evaluation and prioritization, candidate projects are assessed for various factors, including, but not limited to:

  • Accessibility to key economic sectors (e.g. military, port, tourism), high population and employment density
  • Accessibility for low-income and high unemployment areas
  • Vulnerability to projected sea level rise
  • Potential environmental impacts

To perform some of these spatial assessments, a spatial overlay analysis using Geographic Information Systems (GIS) – a framework for gathering, managing, and analyzing data – was done.  Specifically, this analysis involves overlaying candidate projects with various geographies to determine potential interactions/impacts.

The results from this spatial overlay analysis will be input into the HRTPO Project Prioritization Tool.  Looking ahead, project prioritization scores for each of the growth scenarios being analyzed as part of the 2045 LRTP will be completed around the Fall of 2020.  The 2045 LRTP is scheduled to be adopted by the HRTPO Board by June 2021. 

The table below lists the geographies that were included in the spatial analysis. 

Geographies for 2045 LRTP Spatial Overlay Analysis

Census Block groups with High Employment and Population Density

Census Block Groups with above average Low-Income Households

Census Block Groups with above average Unemployment Rates

Higher Education & Workforce Development Sites

Urban Development Areas & Governor Opportunity Zones

Environmental Areas

Military Sites

Major Tourism Sites

Truck/Heavy Industrial Zones

Areas Vulnerable to 3-foot Sea Level Rise

Regional Airports & Port Facilities

Water Bodies

Bus Routes and Stops

Regional Activity Centers

Emergency Sites and Services

 

Maps were produced for each analysis, categorized by roadway, transit, and active transportation candidate projects.  These maps are available in the draft Hampton Roads 2045 Long-Range Transportation Plan:  Regional Needs report.  Below are some example maps from the spatial analysis.
