The Urban sector is a highly tactical environment to test controlled responses to a variety of urban cityscapes, intersection geometries, and configurations.

Creating the Urban Environment

The Urban sector has a total area of more than 392,000 ft2 (36,418 m2) of pavement, 24 intersections, and 4 blocks of potential urban facades. The varied pavement materials and pavement markings within this sector accommodate the testing of vehicle cameras and machine vision systems, while the highly customizable site plan creates environments to meet the specific needs of individual engineering programs.

The 700 ft long (213.15 m), 12 ft wide (3.65 m) multi-lane stretch of roadway with intentionally damaged asphalt features 118 randomly spaced patches of varying length and height intended to replicate the wear and tear vehicles experience in real-world urban settings.
Patch length ranges from 1 ft (.30 m) to 8 ft long (2.40 m), and patch height relative to surrounding pavement ranges from -1.50 in. (-3.80 cm) to +0.50 in. (+1.25 cm). The urban environment is located in the west-central portion of the site and, depending on the specific testing parameters, can support up to 80 unique vehicles and 8 users simultaneously.

Structure Façade Options

The use of shipping containers to create urban façades is an innovative way to add flexibility and adaptability to this urban environment. These containers can be stacked up to 6-high and 60 ft wide and can be outfitted with façades of varying materials, glass, masonry, and composite metal to replicate a wide range of commercial, mixed-use, single-story, and multi-story build conditions representative of real-world urban environments such as urban canyons.

Multi-Lane Urban Street Layout

The multi-lane, multi-intersection, signalized corridor represents a typical Central Business District, complete with pedestrian signal controls. This typical city street grid layout is inclusive of skewed intersections, including signalized and unsignalized intersections.

Unique Traffic Signal Infrastructure

Each intersection is configured with Multiple Controller Types, featuring three traffic signal cabinets at each intersection (Cabinets A, B & C).

NEMA TS 2 Type

Cabinet A is NEMA TS 2 Type 1 cabinet that can utilize controllers such as Econolite Cobalt, Trafficware 980 ATC, Intelight X3, and Siemens M60.

FDOT 334

Cabinet B is a FDOT 334 cabinet that can utilize controllers such as McCain 170, McCain 2070, and Intelight 2070.


Cabinet C is an auxiliary cabinet that has signal cables from cabinets A & B. This is a standard NEMA Size 5 signal cabinet without a controller.
