Dear Mr Sandy: 

This letter is in response to your August 6, 2019 request for the Federal Highway Administration 

(FHW A) to review a roadside safety device, hardware, or system for eligibility for 

reimbursement under the Federal-aid highway program. This FHW A letter of eligibility is 

assigned FHWA control number WZ-387 and is valid until a subsequent letter is issued by 

FHW A that expressly references this device. 

Decision 

The following device is eligible within the length-of-need, with details provided in the form 

which is attached as an integral part of this letter: 

• TSS 590 Water-filled Barrier Channelizer 

Scope of this Letter 

To be found eligible for Federal-aid funding, new roadside safety devices should meet the crash 

test and evaluation criteria contained in the American Association of State Highway and 

Transportation Officials'(AASHTO) Manual for Assessing Safety Hardware (MASH). 

However, the FHWA, the Department of Transportation, and the United States Government do 

not regulate the manufacture of roadside safety devices. Eligibility for reimbursement under the 

Federal-aid highway program does not establish approval, certification or endorsement of the 

device for any particular purpose or use. 

This letter is not a determination by the FHWA, the Department of Transportation, or the United 

States Government that a vehicle crash involving the device will result in any particular 

outcome, nor is it a guarantee of the in-service performance of this device. Proper 

manufacturing, installation, and maintenance are required in order for this device to function as 

tested. 

This finding of eligibility is limited to the crashworthiness of the system and does not cover other 

structural features, nor conformity with the Manual on Uniform Traffic Control Devices. 
2

Results 

3-90 ( 1 1 00C) 

Test 3-90 involves an 11 00C vehicle 

impacting the TSS 590 (Water-Filled) Barrier 

Channelizer at a target impact speed of 62 

mi/h and target impact angle of 0° to 25°. 

The selected Critical Impact Angle was 15°, 

and the target CIP for the left corner of the 

front bumper was the midspan of the 

length of the installation (at the joint 

between segments 20 and 21). 

The results of the test conducted on April 

12, 2019, are found in TTI Test Report No. 

690900-TSRl &2 dated June 2019. The test 

vehicle was traveling at an impact speed of 

63.3 mi/h as it made contact with the TSS 

590 (Water-Filled) Barrier Channelizer at the 

midspan of the installation at an impact 

angle of 14.4°. The TSS 590 Barrier allowed 

the 11 00C vehicle to penetrate the 

channelizer installation in a controlled 

manner. The veh icle came to rest 62 ft 

downstream of the impact point, adjacent 

to the channel izer installation. 

Segments of the TSS 590 Barri er were 

ruptured in the region of the impact. 

However, the resulting detached elements, 

fragments, and other debris did not 

penetrate, or show the potential for 

penetrating the occupant compartment, or 

to present undue hazard to others in the 

area. No occupant compartment 

deformation or intrusion occurred. 

The 11 00C vehicle remained upright during 

and after the collision event. Maximum roll 

and pitch angles were 27° and 17°, 

respectively. 

Longitudinal OIV was 27.9 ft/ sand lateral 

OIV was 3.0 ft/ s. Maximum longitudinal 

occupant ridedown acceleration was 6.3 g, 

and maximum lateral occupant ridedown 

acceleration was 3.9 g. Occupant ri sk 

factors were within the preferred limits 

specified in MASH. 

The TSS 590 (Water-Filled) Barrier 

Channel izer performed acceptably for 

MASH Test 3-90.

the 2270P vehicle to penetrate the 

channelizer installation in a controlled 

manner. The vehicle came to rest 107 ft 

downstream of the impact point, and 60 ft 

towards the field side. 

Segments of the TSS 590 Barrier were 

ruptured in the region of the impact. 

However, the resulting detached elements, 

fragments, and other debris did not 

penetrate, or show the potential for 

penetrating the occupant compartment, or 

to present undue hazard to others in the 

area. No occupant compartment 

deformation or intrusion occurred. 

The 2270P vehicle remained upright during 

and after the collision event. Maximum roll 

and pitch angles were 55° and 10°, 

respectively. 

Longitudinal OIV was 18.7 ft/sand lateral 

OIV was 1.0 ft/s. Maximum longitudinal 

occupant ridedown acceleration was 2.7 g, 

and maximum lateral occupant ridedown 

acceleration was 6.2 g. Occupant risk 

factors were within the preferred limits 

specified in MASH.
