The data collected and used as part of this study include:
- GIS files of existing sidewalks and pedestrian crossings (2013 data)
- Digital aerial photography (orthos), Google Earth, and Google Street View
- Adopted trails and bikeway master plans for each city in which a rail station is located
The information published in the Routes to Rail study shows a reasonable degree of accuracy to provide a snapshot of bicycle and pedestrian networks near existing rail stations in the DFW region. Due to the large number of transportation and development projects in the DFW region, bicycle and pedestrian routes to these rail stations may have changed since the publication of this study. The information in this study does not reflect the physical condition or compliance with the Americans with Disabilities Act (www.ADA.gov) of the existing bicycle and pedestrian infrastructure.
The ArcGIS Network Analyst tool tracks routes from rail stations along the continuous pedestrian network which includes sidewalks, multi-use trails, crosswalks, and unmarked crossings at intersections of minor arterial streets. Physical barriers that create disconnects within the network include highways, access ramps, parking lots, unmarked crossings of major arterials, and sidewalks lacking connections to a pedestrian crossing. Common conditions that create gaps in the pedestrian network are identified below.
Freeway access ramps without marked pedestrian crossings:
In the example above, the lack of a designated pedestrian crossing at the ramp is reflected as a disconnect
in the pedestrian network. Thus, the existing sidewalk to the left of the intersection (red line)
as disconnected from the network. Such locations are examples of areas where improvements
may be targeted to improve the safety and connectivity of the pedestrian network.
A sidewalk or curb ramp at the intersection does not exist:
In the example above, pedestrian facilities on the right side of the street do not extend
to the curb or provide ramps to a crossing and is considered disconnected from the pedestrian network.
Major arterial roadways without a marked crossing:
In the example above, existing sidewalks on the right side (yellow lines) of a major arterial
are disconnected from existing sidewalks on the left side of the street (red lines).
In addition, there are no existing sidewalks on the left side of the major arterial road.
