### New Form of BARS: Road Sign Evaluation (rsEval)

 Road Sign Evaluations (rsEvals) were created on 18 March 2006; however, since that time, their usage has evolved. On 30 May 2008, this BAB was modified to define valid rsEvals.

rsEval (road sign evaluation) involves applying arithmetic to the numbers in a road sign and having the result evaluate to a highway sign for which we have a picture to any or all of the following.

• the highway number on which the sign is located (rsHwyEval)
• RoadHacker's age was when he found the sign (rsAgeEval)
• the number 42 (rs42Eval)
• approximates 3.14 (rsPiEval)
• approximates 1.61803399 (rsPhiEval)
• one of the numbers in the sign that has been duped (rsDupEval)

```   +----------------+
| Gooland      3 |
| Happytown   39 |
+----------------+

rsHwyEval if found on highways numbered 13 (39 / 3), 36 (39 - 3),
42 (39 + 3), 117 (3 * 39), and so on

rsAgeEval if RoadHacker was 42, 45 (39 + 3!), ... years of age
when he discovered the sign

rs42Eval if 3 and 39 can be used in an arithmetic expression
such that it evaluates to 42 (e.g. 3 + 39)

rsDupEval if the 3 is duped such that sqrt(39 - 3) = 3!
```

A Golden RSeval is a road sign that evaluates to the highway on which it was found. `Golden RSevals` have been replaced with `rsHwyEvals`.

The following sign would be a `rsPiEval`.

```   +----------------+
| Fooville     7 |
| Moohaven    22 |
+----------------+

the math is:  22 / 7 = Pi (3.14)
```

The following sign would be a `rsPhiEval`.

```   +----------------+
| Foodale      1 |
| Gootown      2 |
| Mooplains    5 |
+----------------+

the math is:  (1 + sqrt(5)) / 2 = Phi (1.61803399)
```
