Use of A Google-Based Mapping System for Traffic Management Center Web Navigation

There is no commonly accepted method of posting information concerning travel times, incidents, traffic volumes, video images or other traffic management center (TMC) content on the Internet. This lack of a consistent user experience doesn't facilitate the broad use of Internet-based traveler information either through the use of personal computers or through the evolving, portable web-connected devices such as cell phones. During July of 2006 Google started providing real-time traffic speed maps to cell phone subscribers for more than thirty cities. In 2005 Google developed and distributed an application programming interface (API) for their Internet mapping service. The map API allows customers to embed Google maps in the customer's web site. Since the API permits the customer to add overlay images on the maps it is possible to develop TMC web sites that provide traditional functionality but retain the Google style of interface. This paper describes an implementation of the Google API for the Dallas transportation management center (DalTrans). The web site located at provides traditional TMC information including link speeds, camera images, incident information. It also provides light rail locations and the ability to see satellite imagery along with traffic information. A survey of web site users suggests that at least 85% of those using the site and completing the survey viewed the site as easy to use and well organized. The developers of the site anticipate that a consistent user experience on hand-held devices and traditional web sites will encourage a broader use of TMC-based information and more informed decision making by travelers.
