SEDA-COG – Evaluating Corridors of Opportunity

Information on our transportation system plays an integral role in the selection and prioritization of projects for our region’s Transportation Improvement Program (TIP) and Long Range Transportation Plan (LRTP). This map provides a visualization of transportation and land use data across multiple topic areas.

Select the topic area boxes and the listed data layers to see how that information overlays with our planned transportation projects. Learn more about those topic data layers by reading the sections below. Note that combinations of layers can be turned on and off by checking and un-checking the layer boxes. Use the + and – buttons in upper right corner of map to zoom in and out on the map.

SEDA-COG is working to integrate this and other information into the regional project selection process. What other data is important in selecting or prioritizing projects? Let us know your thoughts by providing comments on our LRTP.

PROJECTS:

This layer illustrates the transportation projects included in the LRTP. This includes major asset management projects that are focused on improving bridge and pavement conditions. The Discretionary Project List identifies other regional priorities that have been identified through our outreach to key stakeholders in the SEDA-COG region. Select on the colored lines on the map to view the project title and other relevant details if available.

TRAFFIC VOLUMES:

Traffic volumes are based on PennDOT’s Roadway Management System (RMS) that includes periodic traffic counts conducted throughout the region. These counts include separate estimates of truck volumes. Select the layers to highlight corridors with the highest traffic (>3,500) and truck (>500) volumes. The thicker the lines, the higher the volumes. Select on the layer to see the associated traffic volumes as represented by average daily traffic over a year (AADT).

EMPLOYMENT:

Census Blocks that contain employment centers with over 25 workers.

BRIDGE AND PAVEMENT CONDITIONS:

Asset management projects have traditionally been focused on locations where PennDOT has determined pavement or bridge conditions to be poor. Based on recent data, these layers provide the locations of our region’s poor condition infrastructure. Bridges are separated by whether they are state-owned or owned by the local municipality. As discussed in the LRTP, PennDOT is moving to a lowest life-cycle approach for asset management. As such, poor condition infrastructure may not always be the highest priority for investment.

TRAFFIC CONGESTION:

Traffic congestion is an important consideration in identifying and prioritizing investments that increase the capacity of our transportation system. These layers highlight key congested corridors in the morning or evening peak hours. The data is based on information from GPS units in our region’s cars and trucks. Roads highlighted in orange and red (highest) have the highest levels of traffic congestion.

FREIGHT GENERATORS:

The movement of freight is critical to our national and local economy. Understanding the locations of freight generators is important in identifying key first and last mile connections for freight movement. These locations can guide important transportation investments to ensure businesses can efficiently move goods from their facility locations. The layers provided under this topic area highlight important locations of freight generating businesses and industries.

SAFETY:

Safety remains an important criteria for transportation investments and is emphasized by national performance measures. Select these layers to highlight corridors where there are a high number of crashes. A separate layer also shows the locations of fatal crashes. All crash data represents a 6-year period from 2013-2019.

RESILIENCY:

Resiliency is a new factor that must be considered in transportation planning. SEDA-COG continues to work with PennDOT to identify corridors and infrastructure that is vulnerable to increased storm events and flooding. Select this layer to see high risk flooding locations throughout our region. Segments highlighted in orange and red show those road segments that are considered highest risk. Risk factors include the chance of flooding closure, traffic volumes and current infrastructure condition.

GENERAL LAYERS:

These layers allow one to better visualize our regional rail network and crossings.
