Using a smartphone, computer, or in-vehicle interface, a driver would utilize real-time and/or historical traffic and other data from the Connected Vehicle system in a simple application to determine an optimal time of departure. 


This application would be used by anyone planning a trip that had some flexibility in their time of departure.  This application would benefit any traveler whose travel time was somehow dependent upon congestion, weather, or other conditions as monitored by the Connected Vehicle system.


The primary benefit of this application would be mobility as a user’s travel time could be minimized through selection of the best time of departure.  This application would have positive impacts on safety, mobility, and the environment through decreased drive time and congestion. 

Use Scenario(s)

The application could be used by a variety of travelers using multiple access modes as described in the example scenarios below. An elderly driver wishes to go shopping for groceries and has the flexibility to do so during the day.  They use a Connected Vehicle interface in their vehicle to specify a destination.  The interface returns information as to when the best time to travel would be and how long the trip is projected to take. Family visiting on the weekend wishes to avoid traffic congestion on their trip home.  They access the app on their smartphone and determine when the best time to leave is and how much longer alternative times of departure will likely affect driving time (Figure 1). A person wants to ride their bicycle for recreation and would like to do so when traffic is minimal and weather is good.  They access the application on the internet via their home computer, input their desired route, and determine when they can best enjoy their ride.  

Figure 1.  Departure Time App as Accessed on a smartphone (conceptual)



Users communicate with the Connected Vehicle system using any Connected Vehicle- or web-enable interface.  Connected Vehicle data regarding historical and real-time traffic data is used in conjunction with the user’s route/destination information to return a predicted optimal time of departure and additional predicted travel times for alternative departure times. 

Communication Requirements

The type of communication required would depend upon the interface accessed by the user.  Phone interfaces would likely use cellular or Wi-Fi.  Computer users would use any type of available internet access.  In-vehicle interface users would use whatever Connected Vehicle communication protocol was available and appropriate whether DSRC, Wi-Fi, cellular, or other.


Implementation of the this app would require access to required data whether real-time or historical, creation of the app algorithm for determination of optimal time of departure as determined by desired criteria, and creation of the various device interface apps (computer, phone, in-vehicle).      Attachment(s): ·         Animated GIF file – “TOD Phone App.gif” (for web presentation) ·         Figure 1. -  “TOD Combined.JPG”
