Driving in Shanghai: Traffic lights, big avenues and one-way streets?

Hi SF,
So you mean that you're avoiding the camera sensors by driving on the line in the center of the road right? By doing that it doesn't trigger the sensor? That's interesting.
What about the cameras at traffic lights is there any sensor cameras that fine at traffic light (if running a red light)?

Most of the red light and speed cameras operate and are activated by an conduction (sensing) loop (rectangular shapes most often) embedded in the road surface. Usually these loops are usually confined to individual lanes but not always so. For example at multi-lane intersections where red light cameras are positioned there are often two sets of induction or sensing loops just prior to and then immediately after the white line where vehicles are required to stop at the intersection. Have a look at an intersection where red light cameras are mounted. If one looks carefully enough, one will likely see rectangular patterns on either side of the white painted lines of each lane where cuts has been made to the road surface and the conduction or sensing wire has been embedded. Like I say there are usually two sets of these loops on either side of the white line.

Sometimes there won't be any conduction/sensing loop in the right turn lane if the lane is not controlled by a traffic light/signal "arrow." This is the lane sometimes used by commercial drivers e,g, taxi drivers who become familiar with intersection layouts, to travel through lanes at intersections that have a red light in play at the time. They'd likely be observed using the right turn indicator/turn signal giving casual observers the impression that the drivers intent is to turn right, when actually they then proceed straight thru.

Speed cameras have a similar configuration. Again in multi-lane situations there are often separate conduction/sensing loops (rectangular patterns) for each lane. This means that there are areas often close to lane markings that separate one lane from another where the conduction/sensing loop is not embedded. Once one gets familiar with the configurations and what to look for it is often simple to identify where the conduction and sensing loops are embedded for any given application and situation. That being said though, occasionally conduction/sensing loops extend beyond the boundaries of just one lane. Also some speed camera conduction/sensing loops have multiple loops within or across multiple lanes including any "shoulder" lane e.g. bicycle lane, or sometimes the conduction/sensing loops are offset between multi-direction lanes, dependant on design. Some will trigger even when a vehicle is travelling in the opposite direction e.g. when driven on the wrong side of the roadway. On occasion infrared beams are used, though not as prevalent as the aforementioned conduction loops.

At the moment I only putted the license plate on the back, as the front one is unaesthetic, plus police seems to be satisfied with the rear one only. What’s your opinion? Could it be a problem?
Cheers,

Technically illegal, so if stopped by traffic police, you could either be asked where it is and let off with a warning, fined for not displaying it, not fined and not asked at all. It just depends on the situation at any given time. At the time of re-inspection though the plate must be attached otherwise the vehicle will fail the inspection.
