Regional and/or multimodal traveler information programs intended for travelers en-route to their destinations may make use of 511 telephone systems, in-vehicle devices, radios, or other wireless devices such as pagers and PDAs.


Future ICM systems will require new technical skill sets. Involve management across multiple levels to help agencies understand each other’s needs, capabilities, and priorities.(06/30/2015)

Design a trip planning website to capture and convey real-world factors such as gas prices and congestion information.(May 2011 )

When implementing traveler information systems that promote voluntary changes in travel behavior, incorporate functions for feedback, advice, and action-planning.(16-20 November 2008.)

Use Analysis, Modeling, and Simulation (AMS) to identify gaps, determine constraints, and invest in the best combination of Integrated Corridor Management (ICM) strategies.(September 2008)

Keep technical solutions open-ended in the early stages of an ITS research project, and follow a research oriented contract vehicle.(May 16, 2007)

Use ITS to implement a reliable communications system in work zones.(1/1/2004)

Ensure initial and ongoing success of ITS deployments by providing sufficient start-up time, maintaining flexibility, and performing maintenance needs in-house.(1/1/2004)

Provide consistent and high-quality information to influence traveler behavior.(6/1/1998)

A simulation model estimates that use of route-planning apps can reduce emissions by more than 25 percent.(April 2018)

San Francisco-based tool makes parking more efficient by decreasing parking spot search time by 43 percent.(11/27/2014)

Audible "slow traffic ahead" alerts can improve drivers' situational awareness and increase safety on freeways.(June 2011)

Portland's TriMet and San Francisco's Muni transit agencies saved thousands of dollars in development costs and service fees through the use of Open Source Software (OSS).(May 2011)

Integrated Corridor Management (ICM) strategies that promote integration among freeways, arterials, and transit systems can help balance traffic flow and enhance corridor performance; simulation models indicate benefit-to-cost ratios for combined strategies range from 7:1 to 25:1.(2009)

In 1999, a study in Seattle, Washington indicated that participants who used traveler information devices including wrist watches, in-vehicle components, and portable computers found the information was useful for making travel decisions.(5 January 1999)

In Minneapolis, a traffic incident information pager service was used daily by 65 percent of participants, and at least once-per-week by 88 percent of participants; users decided to changed travel routes in 42 percent of the situations.(10 June 1997)
