(It's rush-hour time. Annie and Wayne are driving their way from the uni to a suburban restaurant. They're expecting a great dinner for their anniversary)
Wayne: What time is it? (Wayne's eyes jump from the congested traffic to the digital clock) Gosh! It's already half pass 7.
Annie: So late! We've been stuck in the traffic for more than 2 hours.
Wayne: Look at that bloke. The traffic is already a mass, and he still wants to take a U-turn at the intersection, as if he owns the street. Some people just don't care any less about others.
Annie: Be cool. Don't let it make you seeing red.
Wayne: Ok, ok, I'll stop nagging about it.
Annie: Don't know why city planners don't synchronise traffic lights along major roads in the city. Drivers just have to sit at every single red light. That's really a waste of time and fuel; not to mention vehicles queuing on streets and churning out fumes. The whole city then just gets clogged up, and gets extra pollution.
Wayne: It is obvious that no attempts to synchronise traffic lights to speed up the traffic flow are being made; instead, most of the traffic lights are synchronised to maximise the waiting time. For that, drivers and passengers are really fossilised in the traffic. We're indeed a part of this city.
Annie: Yeah, fossil in a steaming rage! Have you heard about smart traffic lights? I've seen news on some foreign cities applying smart lights.
Wayne: I've never heard of it. What's that?
Annie: Smart traffic lights are fitted with sensors to collect data of traffic flow on nearby roads. Because these smart lights share all the data collected, they are able to collectively figure out the number and speed of vehicles in specific areas; then instantaneously decide waiting time for each respective intersection.
Wayne: It sounds an interesting idea, and a pretty one.
Annie: Absolutely. And one interesting feature is very much like what we have on our traffic lights, I reckon. I don't know how they exactly do it though, it's not specified in the news. These smart lights tell drivers when they are about to change, so drivers can accordingly adjust their speed to avoid sudden acceleration or braking.
Wayne: Yeah, it's like the countdown signal on our traffic lights, but with different functions. For our drivers, the countdown is the signal for testosterone to kick in; so get your foot off the brake, and plunge down the petrol pedal.
Annie: Typical roadhogs.
Wayne: Yeah, beat the lights is the goal. Smart traffic lights? Give it away; we've got "smarter" drivers.
Annie: Stop nagging, will you.
