Having up-to-date equipment is important to sound traffic signal operations. The signal controller should be upgraded, at a cost of approximately $10,000 each, minimally every 10 years. Routine traffic signal timing updates cost $3,000 or less per intersection.
Facebook. 1  the brand name of a social media service and website, launched in 2004. 2  to communicate with (a person) or search for information about (a person) by using Facebook: My old boyfriend just Facebooked me. 3  to post on Facebook: I facebooked some photos of my cat.
â Total Facebook Impressions = The sum total of all the friends each user who shared or liked â. This is, incredibly (and unsurprisingly) inflated and almost impossible to do.A more realistic calculation is in fact incredibly easy to calculate Facebook Impressions, the simplistic maths are as follow:â every like or share x 250 = maximum Facebook impressions â. The reasoning for this is because Facebook actually limits the amount of users you see in your News Feed.egardless of this, the desire to calculate twitter & Facebook impressions is unprecedented because agencies are gagging to show âthe true valueâ and â explosional â nature of social media and companies are so used to and impressed by impression metrics that they willingly except the figures.
