Roadside Inspections - Using Data to Identify Who to Inspect: ISS and Query Central Brenda Lantz August 2002

Overview < Background of Inspection Systems < The Inspection Selection System < Query Central

Inspection Systems < Development n Improve data accuracy and timeliness n Help focus resources < ASPEN – inspection software n Collects inspection details, prepares report, & transmits data < ISS – Inspection Selection System n Provides inspection recommendation & carrier snapshot with census and safety data

Inspection Systems (continued) < PIQ – Past Inspection Query n Retrieves inspection reports from last 60 days < CDLIS Access – Commercial Driver License Information System Access n Retrieves driver status & conviction history < QC – Query Central n Combines the functions of ISS, PIQ, & CDLIS Access, plus more < For more information:

ISS - Motivation < Relationship between OOS rates, compliance ratings, and accident rates < OOS rate indicator of safety problems, but need reasonable number of inspections to calculate n 40% of carriers with zero inspections n 28% with one or two inspections n 152 carriers with more than 1,000 inspections < Conclusion: Need to better allocate resources to carriers with worst safety performance, and to better distribute inspections among carriers

ISS – Development and Testing < Development guided by a Roadside Technology TWG n Included representatives from Alabama, Colorado, Connecticut, Idaho, Kansas, Michigan, Nebraska, New Mexico, Ohio, Ontario, Virginia, Washington, D.C., and Wyoming < ISS integrated into ASPEN, and first distributed in 1995 < Results: 60 percent increase in the number of vehicles and/or drivers put OOS when the ISS recommended an inspection < ASPEN/ISS is currently in use in 47 states

ISS2 – Development and Testing < Development of SafeStat < ISS2 safety and insufficient data algorithms < Every carrier in MCMIS has an ISS2 value < First distributed in 1999 < Results illustrate just as effective as original ISS

Development of Query Central < Motivation < Carrier, vehicle, and driver information retrieval via the Internet < Single input retrieves data from multiple sources < Provides data analysis & summarization < Data is real time, & generally from the authoritative source
