Handbook for Communicating Travel Time Reliability Through Graphics and Tables
Reliability information is desired by various audiences in different ways. Those with an interest in information range from decision makers, operators, and developers of reliability monitoring systems, to road users and shippers. For example, travelers and shippers want to know when they need to leave, or when the truck has to depart, in order to make an on-time arrival. Both groups also want to know what paths they should use to minimize the likelihood of encountering unforeseeable delays. Managing agencies want to know where the problem spots lie; that is, where the network segments are that make the travel times vary. This report offers numerous ideas on how to communicate reliability information in graphical and tabular form. It describes display options that fall into categories of maps, tables, and figures and graphs. It endeavors to meet the needs of audiences ranging from novices to experts, from those for whom reliability is of cursory interest to those who want to understand all of the details and nuances. This means some of the presentation ideas are very simple while others are more complex. Each is intended to be clear about what reliability information is being presented and how it should be interpreted.
