Proper model selection is essential to the performance of the REACT 350
® II. You will need to
answer the following questions:
1. Are curbs, islands, or elevated objects (delineators or signs) present at the site? What
height and width are they? All curbs and elevated objects should be removed. Curbs
should be removed from behind the backup to approximately 50’ [15 m] in front of the
REACT 350
® II. Any curbs that must remain should be 4” [102 mm] maximum and be
mountable. Signs should not interfere with the system’s ability to collapse. Generally, a
vehicle should not interact with two
objects
at the same time. Allow adequate spacing.
2. If the deployment site is a gore area (place where two roads diverge), what is the angle of
divergence?
3. What is the general geometry of the site? Include the roadway for 500’ [150 m] in front of
the roadside feature, so traffic patterns can be visualized.
4. Is there an existing guardrail or median barrier at the site?
5. What is the width of the roadside obstacle to be protected?
6. Will there be traffic approaching from the rear of the system? Is the system in a two-way
traffic situation with traffic going in opposite directions on either side of the system, or is
the system on the side of the road where cross over traffic is a concern? If yes, then a
transition from the fixed object to the rear of the system may be necessary to prevent a
vehicle from interacting with the rear of the system (pp. 16 and 18).
7. Are there any other unique features at the site that may affect the positioning or
performance of the REACT 350
®
II? See the next page for Other Factors That May Affect
Your System.
Warning:
Do NOT modify the REACT 350 ® II in any way.
Warning:
Safety measures incorporating appropriate traffic control devices
specified by the highway authority must be used to protect all personnel while at
the assembly, maintenance, or repair site.
Warning:
Ensure that there is proper site grading for the REACT 350 ® II
placement as dictated by the state or specifying agency, pursuant to FHWA
acceptance.
