Applying Archived Operations Data in Transportation Planning: A Primer

Long Description for Figure 3. Graphic. Timeline displaying time taken for each activity during the incident.

This graphic depicts an example of how incident data can be used to "drill down" into the details of an event to explain outcomes—in this case, travel time reliability. The diagram has a horizontal time axis. It is divided into six timeline sections and flows along the following process:

Step 1. Detection Time

• Incident Occurs – 6:35 A.M.
• Incident Recorded into CAD (Detection) – 6:42 A.M.

Step 2. Verification Time

• Incident Recorded into CAD (Detection) – 6:42 A.M.
• Incident Verified – 6:47 A.M.

Step 3. Dispatch Time

• Incident Verified – 6:47 A.M.
• Personnel Dispatched and Actions Initiated – 6:49 A.M.

Step 4. Response Time

• Personnel Dispatched and Actions Initiated – 6:49 A.M.
• Responders Arrive to Scene – 6:50-7:00 A.M.

Step 5. Clearance Time

• Responders Arrive to Scene – 6:50-7:00 A.M.
• Incident Cleared and Actions Canceled – 7:15 A.M.

Step 6. Time to Normal Conditions

• Incident Cleared and Actions Canceled – 7:15 A.M.
• Return to Normal Conditions – 8:26 A.M.
