A methodology was established to quantifying the Incident-Induced Delay (IID). The methodology computes the IID using real-time travel time data taken from the Inrix dataset. Delay is determined by calculating the extra delay of the subject profile from the reference profile. Subject Profile is the real-time travel time data from 1 hour before the event start time until 1 hour after the time when traffic gets back to normal in the date that event occurred. Candidate profiles of each event are the real-time travel time profiles of each event from 1 hour before the event start time until 1 hour after the time when traffic gets back to normal in all dates except the date that event occurred. Reference profile is the most similar travel time profile to the subject profile without incident-affected (from incident start time until time when the incident gets back to normal) part of the profile. To establish a Reference profile, a k-nearest neighbor-based method was used. Reference profile is taken from assigning a rank-based weight to the 10 nearest candidate profiles that have the most similar traffic pattern to the subject profile in the duration without incidentaffected part of the profile. Then IID was used to compute the benefits of the Iowa Department of Transportation (Iowa DOT)’s Safety Service Patrol (SSP) program known as the Highway Helper (HH) program driven from delay reduction, emissions reduction, and fuel consumption reduction. Benefit calculation also includes motorist assistance benefit and secondary crash reduction. The final monetary equivalent benefit of DM area is provided in the following table.
