Enlighten User Guide (Android)

EnLighten is designed to be simple and non-distracting. The options are mostly self-explanatory and you will likely use them rarely after you initially set up the App. However, because EnLighten is designed to put the minimum load possible on your phone’s battery, you may sometimes see behaviors that you don’t understand. Please read “About Power Savings” below for some clarifications.

  • If you see EnLighten behaving in a way that seems wrong to you, or if you have suggestions, please use our comment form.

EnLighten’s various screens and options are described below.

Launch and Background Screens

Launch and Background Screens

When you launch EnLighten, one of the main screens at the left appears. An action bar is shown near the top of the screen, with the EnLighten icon and an Info button. On some Android models, there is also a Menu button. If you are in a connected municipality, the appropriate city seal may be

shown. If a crossed-out satellite dish appears, it indicates that EnLighten cannot get the server access it needs to function.

This button produces the About EnLighten screen, shown below, with the option to read the End User License Agreement (EULA).

This button, if present, produces a menu offering Settings and Shutdown options. Otherwise, these options are available through the phone’s hardware menu button.

EnLighten displays any countdowns that occur in the notifications bar at the top of the screen and, if EnLighten is in the foreground, on the main screen. Both cases are shown to the right. When EnLighten is in the background, you can select the EnLighten App icon from the Apps screens or select the notification itself to bring EnLighten to the foreground.

Settings and About Screens

Settings and About Screens

When you select Settings after pressing the menu button on the splash screen, or select Settings from the hardware menu, the Settings screen appears.

If Announce is on, EnLighten announces how many seconds remain until a light turns green.

The Chime Sound selector controls which sound (including “None”) you want to hear shortly before the light changes. Press Done to return to the Settings screen.

If Green Light Assist is on, EnLighten will sound distinctive tones when it knows you will make or miss the next light. (An announcement follows each tone the first 10 times they play.)

The Conserve Battery button tells EnLighten to reduce power consumption when the device is not connected to a power source.

The Wake at Red Light button makes EnLighten turn the screen on when a countdown is available.

Keep Display On While Driving keeps the screen on as long as you are driving, are in coverage, and have enough power reserves.

Selecting Blank Screen When Horizontal will stop EnLighten showing countdowns when the phone is lying down, to discourage handheld use.

The Restore Defaults button (or the corresponding menu item) resets EnLighten to its original settings.

Countdowns

Countdowns

When EnLighten is able to predict a light’s behavior, it can tell the driver using a variety of different countdowns, depending on the current situation. If it can predict precisely, it provides an exact countdown, as shown to the left, which indicates when the light will change. If it can predict only a minimum time till the change, a number with a plus sign, or “Countdown+” will appear, as seen on the right, indicating that the light will remain red at least that many seconds.

About five seconds before the light changes, for an exact prediction, or when the light will change in five or more seconds, for countdown+, the display changes to a white circle around a white car or red circle around a red car, respectively, as seen below, to warn you to get ready to drive.

At an intersection with a separate left-turn signal, EnLighten may show a separate countdown (or countdown+) for through and turning traffic, as shown on the left and right.

Out of Coverage

Out of Coverage

When you are out of EnLighten’s coverage area, the splash screen will be replaced with the “Out of Coverage Area” screen.

If you select the Out of Coverage Area button, the explanation screen at the right will appear, along with a “Request overage” button that will automatically send an anonymous request to Connected Signals asking us to try to add coverage for your current location.

Off-System Signals

Off-System Signals

Some traffic lights are not connected to the municipal traffic net for one reason or another (this may be a temporary or permanent situation). When you stop at such a light, EnLighten displays an “Off-System Light” screen to indicate that no countdowns or chimes will occur at that light.

Pausing and Resuming EnLighten

Pausing and Resuming EnLighten

If you select the Shut Down menu item, EnLighten will stop. You must manually relaunch EnLighten to continue using it.

About Power Savings

About Power Savings

EnLighten tries to achieve a balance between responsiveness and battery life. When you go out of the coverage areas, or stop driving for a few minutes, EnLighten enters a power saving mode where it uses a lower power, less accurate, positioning technology (e.g., cell-towers instead of GPS), and checks your location and speed much less often.

As a result, it may take extra time when you come back into a covered area, or when you start moving, for the app to notice and resume normal operation. If you want EnLighten to wake up more quickly, you can tap the out of coverage icon or go to the Apps Screen and tap the EnLighten icon, either of which will cause EnLighten to fully activate once more.

In addition, if the Conserve Battery setting is checked, EnLighten will only use the device’s GPS when some other app is already using it. This may make EnLighten less effective if the GPS is inactive.

Finally, when operating on battery with a battery level below approximately 20%, EnLighten will temporarily suspend, and not provide countdowns and notifications, which should extend the remaining battery life. When the charge increases sufficiently, EnLighten will resume.
