The TC-400 is a portable, battery powered radar speed sign that was designed to easily be moved and

In it, they explain: "Rated lumen-maintenance life is measured in hours with associated percentage of light output, noted as Lp. In other words, L70 of 30,000 hours means that the tested LEDs produce 70% of the initial light output at 30,000 hours. If an LED has L50 of 30,000 hours, its lumen output decays faster than one with L70 of 30,000 hours."

Regulatory signs describe a range of sign that are used to indicate or reinforce traffic laws, regulations or requirements which apply either at all times or at specified times or places upon a street or highway, the disregard of which may constitute a violation, or signs in general that regulate public behavior in places open to the public.

When a single advance warning sign is used (in cases such as low-speed residential streets), the advance warning area can be as short as 100 feet. When two or more advance warning signs are used on higher-speed streets, such as major arterials, the advance warning area should extend a greater distance (see Table 6C-1 ).

However for non-critical areas the L50 figure may also be used. As a rough guide, most LEDs intended for lighting applications offer L70 values of 50,000 to 60,000 hours, although with improved manufacture of the high brightness LEDs used for lighting, some manufacturers are now quoting figures of 100 000 hours.

Warning signs (black on yellow or orange) cannot bemade from Type I sheeting; Regulatory signs (black on white) must retain a minimum retroreflectivity level of ≥ 50 cd/lx/m 2 (while use of Type I sheeting—with an initial retroreflectivity value of 70 cd/lx/m 2 —is allowed, sign life will be short and may result in poor life cycle value)

Long-term survival of patients with a ruptured or symptomatic aneurysm was similar to that of patients undergoing elective aneurysm repair. Long-term HrQoL of the total study population was worse than that of an age-matched general Dutch population on the EQ-us (range 0-1, difference 0.12).

200 m after passing a warning sign were able to recall the sign (Drory and Shinar 1982). For warning signs to be effective, they should result in drivers reducing their speed. Animated deer (Odocoileus spp.) warning signs have led to a reduc-tion in speed, but only by <5 km/h (Pojar et al. 1975). Similarly, camel (Camelus spp.) warning signs have
