Timed spaces are very effective ways to earn city bucks, but unless you plan the right route you will have a hard time making the most of them. The cars will drive away before you get back to ticket them.
Catching cars parked at timed spaces is all about putting time tint markers on cars and getting back to the car as just as the marker turns yellow while at the same time covering as much area as you can. Time tint markers turn yellow after 15 in-game minutes, so you should try to make a looped route that will take you 15 in-game minutes to complete at the speed you want to go.
The image below illustrates a 15 minute route.
The Route Time displayed at bottom of the Route Menu tells you how about how long it will take you to complete a the route at speed 1.
The image below illustrates a 30 minute route.
At speed 2 you move twice as fast so if the route time reads 0:30 you will complete it in 15 in-game minutes or half the time.
The image below illustrates a 37 minute route.
At Speed 3, a route time of 00:37 will take about 15 in-game minutes (although you may find that you complete the route a little too quickly).
The image below illustrates a 45 minute route.
And at speed 4, 00:45 is a pretty good Route Time.
The faster you plan to drive, the longer your route should be. try different lengths and speeds to find one that works for you.
Once you find the right route length/speed ratio you can start marking cars.
mark every car parked in timed spaces, and when you come back around ticket all the cars with markers that are parked in 15 minute spaces. Even if the marker is still white.
If the cars have yellow markers when you return, you know your route is slightly too long, and if they are still white it is slightly too short, but as long your route is close to the right length they nearly always will have been parked too long.
The third time you come back ticket any cars parked at 30 minute spaces that have red markers (if your route is a little long) or yellow markers (if your route is a little short).
While you are doing this remember to put markers on every new car parked at a timed space.
Since 15 minute spaces are worth twice as much as metered spaces, and 30 minute spaces are worth four times as much, you can earn city bucks very effectively if you are systematic.
It is import and that your looped route does not pass the same timed spaces more than once a lap. If you pass the same car twice in the same lap, you can't simply ticket all the cars with markers, because you may marked them halfway through your route, and you must wait until they are yellow.
if you follow this procedure you will be making big bucks with timed spaces in no time!
