On our city streets we have traffic lights that work with a clock or timer that changes them from red (stop) or green (go). Some of them can see how much traffic is waiting, so they will change when needed. Better light timers might help the flow of traffic so there is not so much polution. Also, on toll roads, trucks can have an electronic device on their window, called E-ZPass, so they won't have to stop at every toll booth. This will help polution that comes from trucks. Better-timed (adjective) lights (noun) rush-hour (noun) E-ZPass system (noun) tollways (plural noun) during (adverb of time) be placing (be is a linking verb) placing (verb) near (adjective)

Before I answer your actual question, there are three things to put right first: 1. grammar, not grammer 2. better-timed lights (with a hyphen) 3. "whether they be," not "whether it be," because the pronoun refers back to "changes" and therefore must be plural. Now, "whether it be" uses "be" in the subjunctive. It is especially used to show a range of possibilities that will follow or to show that there is a distinction or disparity between the list that follows. It is still correct to say "whether they are better-timed lights during rush hour or placing E-ZPass systems near tollways," but not using the subjunctive makes it sound more like those are your only two choices. Here are some examples where I would use the subjunctive "be" because it sounds better to my ear, particularly in writing, but you would not be wrong using the indicative form of to "be." It's a matter of style and preference, and when speaking, especially in casual conversation, you would likely hear the indicative used more often: The color of a man's skin is unimportant, whether he be black, white, brown, green or purple. (You could also says "...whether he's black, white...") Whether I be rich or poor, I'm happy as long as I'm with you. (or "Whether I'm rich or poor...") She enjoys everything about school, whether it be her teachers or her classmates, studying history or French, taking recess on the playground or eating lunch in the cafeteria. (or "...whether it's her teachers...")

It is a simple case of whether-or it is used to give two choices or options better timed lights during rush hour or palcing E-ZPass systems near tollways have been effective ...but in my opinion it is a badly constructed sentence...had to read many times to understand what it meant. Also, did you miss a ? mark after the question?

Not an answer to your question, but something you might like to know: "analysis" is a noun, as in "The analysis of the grammar structure is given in the answer above." The verb form would be "analyze" or "to analyze," as in "Please help me analyze the grammar of this sentence."
