The Idaho Transportation Department (ITD) used a series of interactive web-based applications known as Story Maps to support a robust public involvement program.

Demand for Public Involvement

Idaho is experiencing substantial growth in population. This, in turn, is placing new pressure on the State's transportation systems, including infrastructure and safety. As the need for expanded transportation options increases, so does the potential impact of these projects on communities and stakeholders. Because of this, the need for public involvement in transportation operation, safety, and planning in Idaho is at an all-time high.1

Story Maps

To address this need, ITD introduced Story Maps2, an interactive tool to support public involvement efforts. Story Maps allow ITD to combine project maps with narrative text, images, and multimedia content to communicate with stakeholders and the public about project planning activities. It was developed by Environmental Systems Research Institute (ESRI) and is hosted in ArcGIS online, which is an online geographic information system (GIS) tool. A key advantage of these online GIS tools is that the users do not need to have any GIS or coding experience.

ITD uses Story Maps for long-range, corridor, and modal project outreach efforts. These maps can display safety issues along a corridor, which allows end users to understand these issues in relation with other transportation needs in a specific corridor. Additionally, Story Maps app has the following benefits:

Story Maps in Action

ITD created a series of interactive web-based applications using Story Maps to support data visualization. For example, the Highway Safety Corridor Analysis app incorporated several drop-down panels and hovering and zooming options. The app allowed users to weigh in on proposed safety improvements.

Other ITD web-based Story Map apps focused on the following:


During the 2017 Planner's Summit, it was determined that making work processes and initiatives easily accessible through ESRI Story Maps would allow ITD to best serve its staff and citizens, and therefore ITD would include in its Planning Network (IPLAN). ITD has been working with modal/district staff to update the corridor planning process using Story Maps as a basis to develop a new Corridor Planning Guidebook.
