Rare Facts About Our Brain

  1. The brain doesn’t feel pain: Even though the brain processes pain signals, the brain itself does not actually feel pain.
  2. Your brain has huge oxygen needs: Your brain requires 20 percent of the oxygen and calories your body needs — even though your brain only makes up two percent of your total body weight.
  3. 80% of the brain is water: Instead of being relatively solid, your brain 80% water. This means that it is important that you remain properly hydrated for the sake of your mind.
  4. Your brain comes out to play at night: You’d think that your brain is more active during the day, when the rest of your body is. But it’s not. Your brain is more active when you sleep.
  5. Your brain operates on 10 watts of power: It’s true: The amazing computational power of your brain only requires about 10 watts of power to operate.
  6. A higher I.Q. equals more dreams: The smarter you are, the more you dream. A high I.Q. can also fight mental illness. Some people even believe they are smarter in their dreams than when they are awake.
  7. The brain changes shapes during puberty: Your teenage years do more than just change how you feel; the very structure of your brain changes during the teen years, and it even affects impulsive, risky behavior.
  8. Your brain can store everything: Technically, your brain has the capacity to store everything you experience, see, read or hear. However, the real issue is recall — whether you can access that information.

Highway Design-Parking Along Highways and Arterial Streets

Highway Parking Design
These paragraphs below deal with parking as it pertains to the mainlanes of a controlled access highway, the frontage roads for such a facility, and parking along urban and suburban arterials. Rest areas as parking facilities are not considered in this article.

Emergency Parking

Parking on and adjacent to the mainlanes of a highway will not be permitted except for emergency situations. It is of paramount importance, however, that provision be made for emergency parking. Shoulders of adequate design provide for this required parking space.

Curb Parking

In general, curb parking on urban/suburban arterial streets and frontage roads
should be discouraged. Where speed is low and the traffic volumes are well below capacity, curb parking may be permitted. However, at higher speeds and during periods of heavy traffic movement, curb parking is incompatible with arterial street service and desirably should not be permitted. Curb parking reduces capacity and interferes with free flow of adjacent traffic.
Elimination of curb parking can increase the capacity of four-to-six lane arterials by 50 to 60 percent. If curb parking is used on urban/suburban arterials or frontage roads under the conditions stated above, the following design requirements should be met:
  • provide parking lanes only at locations where needed
  • parallel parking preferred
  • confine parking lanes to outer side of street or frontage road
  • require that parking lane widths be 10 feet [3.0 meters]
  • restrict parking a minimum of 20 feet [6 meters] back from the radius of the intersection to allow for sight distance, turning clearance and, if desired, a short right turn lane.
