- Lake, LaPorte, and Porter in Indiana
- Kenosha, Milwaukee, Ozaukee, Racine, Walworth, Washington, and Waukesha in Wisconsin
3. Why is the Travel Midwest site unique?
There are several websites which have pieces of information for different parts of the Travel Midwest area, but the Travel Midwest site is one place where information on the entire area is available in driver-friendly formats and can be linked to easily. Sometimes construction or an accident in another state affects the highways in your state. The Travel Midwest site gives you the picture across state lines. Unlike many other sites, the site also has an open policy on sharing the traffic information at no charge.
4. Where does the information come from?
The system receives traffic data from all major traffic management systems in the area, including the Illinois, Indiana, Wisconsin, Michigan, Minnesota, and Iowa Departments of Transportation, the Illinois Tollway, the Chicago Skyway, the Indiana Toll Road, and the City of Chicago and Lake County Illinois Divisions of Transportation. These systems use a wide range of traffic detection technologies to monitor speed and concentration of vehicles. Based on the collected data, traffic congestion levels and travel times are computed. These systems also provide messages currently displayed on dynamic message signs located along the roadways.
Information about incidents and construction-related road closures is received electronically from several site contributors. Additional information is entered manually by Travel Midwest operators from a series of reports, and the operators also check and correct the automated accident entries. This blend of automatic data and manual entry help to keep the information available to drivers as current and accurate as possible.
5. How does automatic traffic data get to the system?
There are currently many types of vehicle sensors available, including inductive loop, microwave radar, infrared, ultrasonic, acoustic, and video image processing. There are embedded in-roadway sensors and above-roadway sensors. The Gateway System has a blend of both types. In general, these sensors detect the presence and passage of vehicles.
The collected data is transmitted from the field via a variety of communication links to a central control system, where it is further processed and distributed.
6. How can I view a map of my preference without zooming and scrolling one of the maps from the "Maps" menu?
The Travel Midwest web site home page now presents a map. As you scroll and zoom that map and turn layers on and off, the location, zoom and layer information is stored in a cookie on your browser which is retained for three months. When you return to the site home page or select "My Map" from the "Maps" menu, the saved map configuration will be displayed.
7. Why does the travel time and congestion information disappear when there are major construction projects, when we need the information the most?
Unfortunately, most major construction projects involve removal of the existing roadbed and other activities that interrupt the operations of the traffic sensors and/or their communication to the central control system. Once the construction activities are over, operation of the affected traffic sensors are restored. Until then, there is no way to get the data.
Occasionally, a project will allow for the installation of temporary sensors to fill the gap during construction, but this is not always feasible. Every effort is made to bring the sensor systems back into operation as soon as possible.
8. Is the Miles Per Hour (MPH) given the minimum, maximum, or actual speed?
The reported speed is an estimate based on traffic sensor data, and it is re-calculated at various intervals ranging typically from one to five minutes.
9. How current is the information listed on the website?
The currentness of the information on the web site varies by type of information and also by source.
- Incidents are entered into the system and updated manually by the Travel Midwest operators. There is some delay because incident information needs to be manually collected and verified.
- Construction information is entered manually by the Travel Midwest operators on a daily basis.
- Traffic updates are automated and arrive at various intervals with a typical frequency of once every five minutes.
- Dynamic message sign updates are also automated and typically occur whenever there is a change to the message.
10. I see construction indicated on the map, where can I get more information?
You can view construction reports by accessing the Construction menu item on the Reports menu on the Travel Midwest site. You can get a short summary of work planned on all of our covered highways and roads. Additional information on slightly more involved items may be found on the Construction Announcements page. Many of the major long-term projects such as the reconstruction of an entire interstate section have their own websites. The Projects menu includes menu items which link to the websites of such projects. In addition, the Links page has the links to the individual state Department of Transportation sites where even more extensive information is available.
11. What is the schedule for the Kennedy reversible lanes?
|Day of Week||From||To||Target Start|
|Monday - Thursday||Inbound||Outbound||12:30 PM|
|Monday - Friday*||Outbound||Inbound||11:00 PM|
Major holidays follow the Sunday Schedule. This normal schedule may vary depending on traffic congestion, incidents, road construction, and storm alerts.
*The Friday afternoon schedule may be altered to accommodate heavy inbound travel times. In those instances the flip from outbound to inbound may occur as early as 6:00 PM based on congestion, impacts to other facilities, incidents and special events.
The reversible lanes are operated based on both a schedule and as necessary in order to respond to special events, conditions, and incidents on the highway.
The Reversible lanes affect a large portion of the downtown expressway network, not just the Kennedy Expressway itself. For exmaple if the reversible lanes are running inbound towards Chicago then they are not available to relieve congestion on the inbound Dan Ryan, and Stevenson Expressways. The reversible lanes nearly always are open in the direction of higher volume of vehicles although the corresponding travel time may be lower due to the extra lanes going in the direction of that higher volume.
12. Does the site have driving directions?
No. The Travel Midwest site has information on the expressways, tollways, and a few limited access highways. To be truly useful, driving directions need information on other roadways not currently included in our data. From our Links page, you can access several of the sites that have driving instructions, though many do not have the congestion and construction information. These sites include www.mapquest.com, www.mapsonus.com, www.zip2.com, www.mapblast.com, maps.google.com, maps.yahoo.com and expediamaps.com. Links are continually being added to this area for the convenience of our users. If your favorite site is not included under the Links section, use the Contact Us page to send an email to the Travel Midwest webmaster telling us about the pages you would like to see included.
13. Does the site include traffic information on arterial streets or other highly traveled roads?
Incidents, construction, and special event information on arterial roadways throughout the coverage area is displayed on the Travel Midwest site's maps and reports. Congestion data is available for major arterials in Chicago and camera snapshots are available for Lake County, Illinois. The site also includes information from several dynamic message signs on arterial roadways in the Chicagoland area.
14. Do you have bus and train information in addition to road information?
You can access bus and train information via links to the transit agencies in the coverage area on the Travel Midwest Links page. Transit and Intercity Rail sites are grouped by state. Transit incident and service disruption information is available via announcements and links on the Travel Midwest Transit Incidents page.
15. Does your site list airport parking information?
You can access individual airport websites through the Links page of the Travel Midwest site. Each airport in the region has a website with driving instructions from major interstates, and parking data. The airport sites contain parking restrictions, cell phone lots, and other special instructions that visitors to the airports will need. The Links page of this site has links to all of the airports in the region with scheduled air service.
16. What do the road colors on the map mean?
The colors on the map are designed to give a quick visual picture of the state of the covered roadways. Each color represents an estimated level of congestion on that road segment:
- (dark green): Uncongested
- (light green): Light congestion
- (yellow): Medium congestion
- (red): Heavy congestion
- (gray): Unknown congestion
For expressway segments, the congestion levels are determined by the traffic speed, and the ranges are:
- Uncongested: 55 or more mph
- Light congestion: 35 to 55 mph
- Medium congestion: 15 to 35 mph
- Heavy congestion: under 15 mph
For arterial roadways, the congestion levels are assigned by the originating agency. The congestion levels in the city of Chicago are also determined by the traffic speed, and the ranges are:
- Uncongested: 30 or more mph
- Light congestion: 20 to 30 mph
- Medium congestion: 10 to 20 mph
- Heavy congestion: under 10 mph
If you have difficulty distinguishing the congestion colors on the map and reports, you can click on the ADA icon next to "Uncongested" in the Map Legend or the Congestion Legend on the Congestion Report or Travel Time Report to open a window that lets you set the color used for "Uncongested" to blue, which is easier to distinguish from the red for "Heavy" and the gray for "Unknown".
17. Why do some pages look strange or not come up properly?
The Travel Midwest site is designed to work primarily with current versions of popular browsers such as Microsoft Internet Explorer, Firefox, and Safari. Internet Explorer 6 is not supported.
18. Can I access Travel Midwest information on my PDA or cell phone? Is there a mobile app?
Yes. However, you must make sure that your phone is compatible with web access and that your cellular service provider offers this service. While the Travel Midwest information is offered free of charge, your cellular provider may have a charge for connecting to the web.
The Travel Midwest mobile app is free and provides a scrollable and zoomable map, messages, and notices. The mobile app is available for iPhone and Android compatible devices:
|For iPhones||For Android Devices|
For older mobile phones, the Illinois Department of Transportation provides the availability of a wireless-friendly version of Chicago Area Travel Times as part of the overall traveler information services. This feature is an extension of our existing Chicago Quick Traffic Report that displays travel time information within the Chicagoland area. If your mobile device supports Wireless Markup Language version 1.1 (WML 1.1) and Wireless Application Protocol 2.0 (WAP 2.0), you can access this service at www.travelmidwest.com. You can then navigate through a list of Expressways and Tollways to access a list of travel times for the chosen route.
We anticipate that most users will have no trouble with the new page. We ask that those experiencing difficulty with the new wireless report to email us at Travel Midwest webmaster. Include your cellular service provider and device make and model to help us identify any issues.
These features are not intended for use while operating motor vehicles. Please drive safely and responsibly.
This information is also on the Announcements page of the Travel Midwest site. Every effort will be made to ensure that the Travel Midwest site is compatible with new wireless devices.
19. Can I get timely traffic information sent directly to me without having to go the web to get it?
Yes, the Travel Midwest Alerts System is a free service that provides email notifications of up to date traffic information on user-selected trips along the expressways in the Travel Midwest coverage area. You can define one or more trips using the Travel Midwest Trip Report, and then press the "Email Alerts" button to create an account to receive traffic information along that trip. The format, contents, and timing of the alerts for each trip are customizable. For more detail on defining trips and registering for email alerts, see Trips and Alerts Help.
20. I thought I signed up for the Alerts System, but I am not receiving anything. What should I do?
The registration process for the Travel Midwest Alerts System requires an email verification. After you completed the registration form, you received an email at the email you entered that contains a link that you must click to activate your account and begin receiving notifications for your selected trip(s). This process ensures that only those who wish to receive the email notifications do so. If you do not see the email, check your spam folder to ensure that the confirmation email is not being filtered. If you cannot find the email, go to the Update Alerts Account page and enter your email address and password. A dialog will be presented stating that your account has not been activated which includes a button "Send Activation Email" that you can press to have another activation email sent to you.
21. How do I report a pothole?
In the Chicago area, you can report potholes on interstates including toll roads by calling the *999 Cellular Express Line. For other roadways, report potholes on expressways and state owned roads to the state DOT. Pothole reports for local roads under municipal jurisdiction should be reported to the applicable municipal public works department.
22. How do I report debris in the roadway?
You can report debris to the *999 Cellular Express Line in the Metropolitan Chicago Area. Outside of the Metro Chicago Area, contact the public agency that is responsible for operating/maintaining that specific roadway. You can find some of those agencies using the Links page of this website.
23. What do I do if I see an accident or incident on the roadway?
Call 911 for emergencies and accidents.
24. What do I do if I have a question or comment on the Travel Midwest site?
For technical assistance with this website, you can use the "Contact Us" item on the "about" menu or the page footer to contact the Travel Midwest webmaster.

27. How do I know if the travel times I am seeing on one of the highways included in your website are high, low, or average?
Historical travel time data for comparison to real-time conditions is available on our companion website, www.travelmidweststats.com. You can also access the statistics via links on the Travel Time Report page and on the small window that is displayed when you click on a travel time icon on a map.
28. I would like to evaluate alternative routes to plan my commute or a trip. How can I obtain information about the typical travel times on various routes?
Historical travel time data is available on our companion website, www.travelmidweststats.com. You can also access the statistics via links on the Travel Time Report page and on the small window that is displayed when you click on a travel time icon on a map.
29. How can I tell in which direction an IDOT camera snapshot is taken?
If you click on an IDOT camera snapshot in the Camera Report, a small window will open containing the snapshot enlarged and reference views labeled with their directions that you can use to determine the direction in which the camera is pointed.
30. Why are the Illinois Tollway congestion levels and travel times sometimes less accurate?
The Gateway system gets data from a variety of sources - Illinois DOT, Illinois Tollway, Indiana DOT, etc. These agencies use a variety of mechanisms to provide their raw data - pavement loop detectors, transponder toll tag timestamps, etc. In the case of toll tag transponders, the data is by nature coarser and potentially less timely than direct roadside-based systems. In particular, these data can suffer from latency issues because of delays in receiving the same. For example, if motorists are delayed by heavy congestion, the system is initially unaware of this problem until the motorist passes through the congestion and reaches a toll plaza (or exit) where the toll tag is read. That situation inevitably results in extra delay before the end point timestamp is read. Additionally, the system is unable to determine the precise location of congestion since the data only indicate a delay between two points sometimes spaced far apart (for example 2 toll plazas). This results in long map segments with the same color congestion coding.
The Illinois Tollway is expanding the sources of data used to provide travel times to the Gateway which will allow more granular congestion data to be presented in the future. At a minimum, congestion data will be provided between entrances and exits to the system.
31. What is the source of Chicago arterial congestion data?
All of the Chicago arterial congestion data is provided by the Chicago Department of Transportation (CDOT). CDOT estimates the real time arterial congestion based on the movement of transit (CTA) buses on about 300 miles of principal arterials. Location and speed data from the GPS equipment on board the buses are processed by CDOT in real time to estimate the arterial congestion.
32. Why are many Chicago arterial segments not showing congestion information?
Currently, Chicago arterial congestion is estimated based on the movement of transit buses. During off peak hours, nights, and weekends, the CTA bus services over many of the segments are limited. This limits the availability of congestion estimates on segments with infrequent bus service. In the future, CDOT plans to include other probe based and automated detector data sources for congestion estimation to supplement the bus probe data.
33. Is there a way I can get traffic information on my AM/FM radio?
Yes. Highway Advisory Radio (HAR) towers that provide bulletins to motorists and other travelers regarding traffic and other delays are located throughout the Chicago area as shown on the map below. Please note that some towers are under construction or temporarily out of service. See the list below the map for more details.

34. I am a subscriber to Gateway Traffic Information and I received an email stating that I must update my account information. What do I do?
As stated in the IDOT Traffic Information Access/Reuse Policy to which you agreed, you are required to update your account information when it changes, and must update this information at least annually. To do so, please go to this URL: https://www.travelmidwest.com/gcm/ (note that the URL begins with "https", not "http"). Then log in by selecting "Login" from the "admin" menu and entering your user name and password in the form that appears. To update your registration information, select the "Update Account" menu item from the "admin" menu. Make any changes necessary on the Traffic Information Access Account Update page and then press the "Update Account" button. You may delete your account if you wish by pressing the "Delete Account" button on that page.
35. The incident, construction, and special event icons on the map are rather large when the map is zoomed out. How can I find out exactly where an event is occurring?
When you click on an icon, an entry is added to the top of the Info Viewer describing that event, including its exact location. You can also use the zoom-in control to zoom in to the icon's location to see it more clearly.
36. Where can I get video from a camera I saw along the roadway?
The camera information on the Travel Midwest website is provided by the various agencies and we do not own, archive, or control the cameras or camera data. Please contact the appropriate agency for more information.
37. What is a moving operation?
A moving operation is a construction event in which vehicles, equipment, and/or workers are either continuously moving along the highway at a slow speed (e.g., mowing or sweeping) or are moving along the highway between work locations and stopping at each location for a brief period of time (e.g., changing light bulbs). For the traveler, a moving operation on the Travel Midwest Construction Report does not signify that there is construction along the entire length of the given location. It indicates that there is a crew moving along the highway at some point along that location, possibly with brief stops. There may be congestion at the point at which the crew is working.
38. I didn't see my question. What do I do?
Not every possible question is listed here, just some of the most common ones. Please click webmaster email to send a message to the Travel Midwest Team. A team member will get back to you.
