Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

1. With the new highway interchange at a dangerous street intersection, police records indicate an average of 5 accidents per month. The Department of Traffic Safety wants to investigate the probability of the following occurring in any month:a) No more than 4 accidents.c) At least 2 accidents.b) A single accident.d) At most 2 accidents in 15 days.
The state transportation agency has established crash reduction factors shown in the table. An intersection has been identified as having an abnormally high left turn crash rate (17, 20, and 18 crashes in the last three years), attributed to excessive speeds and the absence of an exclusive left-turn phase. The ADT of the intersection for the last three years is 8,400, and the ADT for after implementation is 9,500. Determine (a) the appropriate countermeasures and (b) the expected reduction in crashes if the countermeasures are implemented. .
