We updated the majority of our traffic maps to AJAX formatting, allowing for faster and easier use. Below are step-by-step instructions on how to navigate these new maps.
How do I move the maps?
Just like with our old maps, you can still navigate to focus on a specific area of interest. You can do this in one of three ways: click and drag, use the arrow compass, and by right clicking.
Click and drag
1. Left click anywhere directly in the map.
2. While holding the clicker down, move the mouse in the opposite direction of your area of interest, essentially dragging the map toward that area.
3. Release clicker to stabilize map.
4. Repeat as many times as is necessary to reach your area of interest.
1. Locate the arrow compass in the left hand corner of the map.
2. Left click on the arrow of the direction you wish to move.
3. The map will pan over a bit in the intended direction.
4. Repeat until you reach your area of interest.
1. Right click and release anywhere directly on the map.
2. A small text box will pop up with the options "zoom in, zoom out, up, down, left, right".
3. Left click on any of these options to navigate as you desire.
How do I zoom in the maps?
There are also several ways you can zoom in or zoom out on the map. There are four different zoom levels to help you get the perspective you desire.
1. Double click your left clicker anywhere directly on the map to zoom in one level.
2. You can repeat to zoom in more until you reach the closest level.
1. Locate the plus and minus zooming tool in the left lend corner of the map under the arrow compass.
2. Left click the plus sign to zoom in a level.
3. Left click the minus sign to zoom out a level.
4. The highlighted orange bar indicates the level of zoom you are viewing.
5. Repeat until you are viewing the desired zoom level.
1. As mentioned previously, when you right click anywhere on the map you will see a text box with the options "zoom in, zoom out, up, down, left, right".
2. Left click on "zoom in" or "zoom out" until you are viewing the desired perspective.
How do I use the weather information?
On all of the maps, you will notice weather icons next to temperatures, indicating the current localized weather conditions. To view more information including location, descriptive details, humidity level, wind speed/direction, atmospheric pressure, and dewpoint temperature, roll your cursor over the symbol of interest and a text box of information will appear.
Left click on the symbol to view a seven day forecast. The forecast will appear in the upper left corner of your screen with the high and low temperatures, descriptive details, and chance of precipitation for each day.
How do I read the symbols and road color keys?
To view symbols indicating live traffic information directly on the map and current weather information, make sure all of the checkmark boxes located at the top of the map are selected.
Left click blank boxes to view more symbols, or left click checked boxes to un-check them. This allows you to customize the types of symbols you would like to view (Ex: The map with the options selected below would contain symbols pertaining to accidents, cameras, and weather, but not any roadwork symbols).
Here is a key to all of the symbols:
You can also view more details by simply rolling your cursor over the symbols.
Large freeways and highways are highlighted with the color corresponding with the current speed of the traffic flow. Green = 45 mph or faster, yellow = 25 mph to 45 mph, and red = 25 mph or slower. You can also view more exact speeds by rolling your cursor over the road of interest. If a freeway or highway is not highlighted in any color, then we do not currently have traffic speed information for that road.
How do I navigate older maps?
To move the older maps to focus on a specific area, simply use the navigational arrows surrounding the map labeled N (North), NE (Northeast), E (East), SE (Southeast), S (South), SW (Southwest), W (West), and NW (Northwest). By left clicking on any of these arrows, the map will be shifted in the direction the arrow indicates. This can be repeated until you reach your desired location.
Using the Traffic tools
To zoom in or zoom out, use the numbered (1-7) zooming tool at the top left hand corner of the map. Left click the plus sign to zoom in. Left click the minus sign to zoom out. You can also left click any of the numbers to indicate your desired zoom perspective. The level you are viewing will enlarge and show orange.
The grey bar at the top of every traffic map page contains links to important traffic tool pages such as Travel Times, Forecasts, Map, Incidents, and Cameras. Not all maps will have all of these options listed if data is not available in that area for that feature. Left click on any of these tabs to access the desired page.
How do I use Travel Times?
The Travel Times page shows popular routes and their current travel time according to current traffic flow speeds, weather, and delays. The current travel time will give you the estimated amount of time it currently takes to travel the route from start to exit, assuming your average speed is as reported by the real-time speed sensors we have access to, or that you are going the speed limit where no sensors are available (therefore giving you the minimum travel time based off of current conditions). This number estimation will be color coded, comparing the current travel time to the ideal travel time:
- green (close or faster than the ideal travel time)
- orange (3-7 minutes over the ideal)
- red (7 minute or more over the ideal)
The ideal travel time indicates the time it takes to travel from start to finish on the route indicated while constantly driving the speed limit. The sensor coverage indicates the portion of the route covered by active speed sensors. The higher the percentage of sensor coverage, the more accurate the travel time.
You can also left click on the name of the route to highlight the information for that route and display the route on the map below, as indicated by the purple line. If you would like to create custom routes to view different travel times, you must create a My Traffic account.
How do I use the traffic forecast?
Travel time forecasts are computed using historical information based on the day and time. Left click on the name of any route to view graphs of the estimated travel time forecasted over a seven day period. Each graph is labeled by day and include a red line indicating the travel time (in minutes) throughout the day (in hours). The grey region indicates the peak traffic times that should be avoided. By leaving before or after these peak times, you can save a lot of time from being in traffic. You can also create custom routes to obtain custom traffic forecasts by creating a My Traffic account.
How do I read incidents information?
The incidents page lists all traffic incidents under the freeway/highway they are located on. This includes all of the information that can be seen on the map as represented by symbols, including accidents, roadwork, planned events affecting traffic, obstructions, etc. (for a complete list click here
The term "Dir" indicates the direction of traffic affected by the incident with the letters N (northbound), S (southbound), E (eastbound), or W (westbound).
To view more details about the incident description, left click the green plus sign in front of the description and scroll down to the bottom of the freeway/highway where the incident is located. A blue description bar will appear with more information.
How do I use the Traffic Cameras?
Traffic cameras are only available for some locations. You can left click on the camera icon directly on the map to view a live traffic picture in the left hand corner of your screen or you can click on the traffic video camera icon to view a live traffic video on your video player.
The camera page allows you to view a list of all of the traffic cameras in your area, their location, and a link to the live traffic picture or video.
