Maps provide a key method of communicating plans. We've included here maps of all the transportation networks, maps of general areas of where people live and work, maps of traffic counts, and more.

Metropolitan Planning Area

Check out "Our Planning Area" for a map of Central Indiana's Metropolitan Planning Area (MPA) and Urbanized Area Boundary (UAB).

Central Indiana Ride Guide

This is a resource for bicyclists and bicycle network planners. It maps all of the open bikeways in Central Indiana, streets identified as being low-stress for cyclists, and various cycling amenity locations. The bicycling amenities were identified by the public, bicycling organizations, and community engineers in early 2021.

Crash Data Dashboard

The IMPO began a project in 2017 to correct the locations of the ARIES (Automated Reporting Information Exchange System) incapacitating injury and fatal crash records. The IMPO’s crash dashboard displays 6 years (2015 – 2020) of fatal and incapacitating injury crash records in the 8-county region. The dashboard enables the IMPO’s Local Planning Agencies and the public to view the crash data with interactive filters that allow the user to select a specific year, crash type, or jurisdiction. Each individual crash location can also be selected for further crash details. Please contact Jennifer Dunn for more information on the Crash Dashboard or the corrected ARIES Crash Data.

High Injury Network and High Crash Intersections Map

The IMPO developed a High Injury Network (HIN) to identify the local corridors with the highest frequencies of crashes resulting in incapacitating injuries and fatalities within the region.

To construct the HIN, the IMPO used spatially verified vehicle, pedestrian, and cyclist crashes that occurred in the public right of way between 2016 and 2020, excluding crashes on interstates and expressways (with the exception of at-grade intersections and ramp intersections). Severe crashes were joined to eligible intersections and roadway segments. Candidate corridors spanning two or more intersections in the top 20th percentile by severe crash frequency were then identified. Over 500 centerline miles of candidate corridors across the region were scored by the number of severe crashes per mile, with fatal crashes receiving a higher weight. The top 234 miles, representing approximately 10% of the 2,358 miles of arterial and collector centerline miles not owned by INDOT, were then assigned to the HIN. The HIN represents 29% of crashes resulting in an incapacitating injury or fatality reported on local streets between 2016 and 2020 but is made up of only 10% of locally owned collector and arterial streets and roads.

Traffic and Bike Counts

Traffic counts can be useful tools for many purposes. They help transportation planners understand roadway volume and changes in volumes over time. Developers can use them to evaluate prospective sites. You can find some traffic counts on this website and links to other helpful sites here as well.

Functional Classification

Categorization helps us to understand how an individual part performs as part of the overall network. For roads, that organizational system is called the functional classification system (FCS). Roads are categorized by a number of factors, but mainly categorization is determined by the function of the road. Roads that are designed to move vehicles faster have a higher mobility function; roads designed to provide access to homes and businesses have a higher access function.

Environmental Justice Areas

Environmental Justice (EJ) refers to the process of evaluating and analyzing the planning process in reference to the most disadvantaged populations. Environmental Justice populations are identified by the federal government as low-income and minoritized populations. As part of our planning process, we evaluate the impact our projects have on these populations.

Regional Freight Network

The 2016 Regional Freight Plan was adopted with the vision of “Supporting economic growth and competitiveness throughout the region, while reducing the environmental and community impacts of freight.

National Highway System

The National Highway System, or NHS, is a network of nationally-significant roadways that moves people and freight across the nation. These routes include interstates, state highways, and intermodal connectors.

2019 Safety Study: Road Safety Audit of High Crash Intersections

This map identifies 24 high-crash locations within the Indianapolis Metropolitan Planning Area (MPA). This includes 5 high priority Pedestrian and Bicycle locations. For each location, the team reviewed crash data and existing conditions, created a collision diagram, conducted a field check, met with local engineering and police representatives, and identified specific improvements to remedy existing safety issues.

2016 Safety Study: Top 50 Most Dangerous Intersections

This map identifies the top fifty (50) high-crash locations within the Indianapolis Metropolitan Planning Area (MPA). For each location, the team reviewed crash data and existing conditions, created a collision diagram, conducted a field check, met with local engineering and police representatives, and identified specific improvements to remedy existing safety issues

Red Flag Investigation

A Red Flag Investigation (RFI) is a quantitative analysis of infrastructure, water, hazardous materials, historical features, and other data within a half-mile of a proposed transportation project. The MPO has created a standard procedure for developing an RFI that is based on Indiana Map and other readily available datasets


The Indianapolis MPO tracks census data for the Central Indiana region.

Transit-Oriented Development Map Series and Dashboard

Transit-oriented development, or TOD, is a type of urban development that includes a mixture of housing, office, retail, and/or other amenities integrated into a walkable neighborhood located within a half-mile of quality public transportation. This story map series will look at the three planned bus rapid transit corridors in Marion County to evaluate current conditions and trends over time.
