Wisconsin’s Top Level Design
CVISN Design WorkshopMay 30 – June 1, 2001
New Orleans, LA
Wisconsin CVISN Objectives Provide efficient application,
processing and delivery of motor carrier credentials (e.g. registration, tax payments, permits, etc.)
Increase the efficiency and effectiveness of CVO enforcement
Enhance safety of commercial vehicle operations
Wisconsin Features Staggered IRP registration schedule
built around IFTA activities No state HazMat program Deployment of statewide directory
for interaction between citizens and state
OSOW Permit Unit staff handle many functions that are performed by engineers in other states.
Key Strengths Organizational factors Experience in CVISN-related
activities Underlying technology
infrastructure
Organizational Factors Single-agency umbrella for CVO
regulation and enforcement DOT Technology Management
Council Flexible procurement practices CVO Business Plan used to guide
activities – proven valid over time
Challenges: Organizational Legislature privacy concerns Biennial budget process timing Securing state matching funds DOT Technology Management
Council project prioritization Proposed Department of Electronic
Government Multi-vendor environment
CVISN-Related Experience MOOSE – MCSAP Out Of Service
Enforcement Deployed between WI and MN Snapshots used to determine red-light License plate reader Data sharing between states Standardized data and report formats Timing of data – critical issue
CVISN-Related Experience MCES – Motor Carrier Enforcement
System Collects information from every contact
that State Patrol has with carrier and vehicle
Beginning of SAFER-like functionality within the state
Operational since 1987 – 14 years of data
Available real-time at SWEF
CVISN-Related Experience OOPPS – Oversize / Overweight
Permit Processing System On-line application for annual permits Limited self-issuance of single-trip
permits using table-driven routing Will expand to include on-line renewal
of annual permits, automated routing engine, and electronic payment acceptance
CVISN-Related Experience Expertise in various information
systems technologies that will be useful for CVISN deployment IBM VisualAge for Java JavaBeans and Enterprise JavaBeans IBM DB2 Oracle IBM WebSphere
Technology Infrastructure Statewide wideband network Single state mainframe data center Agencies have their own separate
LANS Every Safety and Weight
Enforcement Facility (SWEF) has had access to most state and federal systems since 1987
Technology Infrastructure Mobile Data Computers (MDC)
Operational since 1997 Deployed in entire fleet including
Motor Carrier Enforcement vehicles and 90+ individual law enforcement agencies
Dual Web sites – WisDOT and vendor (The Polk Company)
Challenges: Technological Electronic funds transfer and credit
card acceptance a work in progress Timing of XML alternative
availability affects WisDOT and Polk development plans and strategies
Multi-vendor environment Connectivity to Clearinghouses Data scrubbing for routing engine

Top Level Design Principles Messaging/Queuing approach to
application integration Minimize interfaces to external
systems Snapshot updates will be done on
transactional basis Minimize Legacy Applications Changes Communication among state legacy
systems use existing syntax
Key Top Level Design Features Messaging Interface CVIEW PrePass with integrated WIM ASPEN Equivalent Carrier Access
Messaging Interface (MI) Communications among state systems
handled via the MI Routes transactions between legacy
applications, CVIEW, CI & Roadside Employs scripts associated with specific
transaction types Provides application connectivity across
different hardware/software environments
CVIEW CVO Snapshot summary database for
both interstate and intrastate carriers Interface to the SAFER system Bi-directional distribution hub
between roadside systems and SAFER Interface to PrePass PreView for
periodic SnapShot updates
PrePass with Integrated WIM Combination of PrePass and mainline
WIM for screening PrePass roadside screening computer
updated every 80 minutes CVIEW provides periodic Snapshot
updates to PrePass PreView Message boards signal pull in/bypass at

ASPEN Equivalent Builds on current MCES functionality Replaces current 3270 configurations
at SWEFs with MCES Client Client Provides SWEF access to

Hope to ultimately link Client to PrePass screening computer
Carrier Access Accommodates web and computer to
computer access Transactional web access available to
limited number of carriers for OSOW today
Piloting Polk COVERSnet web access to IFTA

Network Connections
CVISN Level 1 ComplianceSafety Information Exchange
ASPEN (or equivalent) at all major inspection sites.
We have implemented our MCES (ASPEN equivalent) at all sites
Connection to the Safety and Fitness Electronic Record (SAFER) system to provide exchange of interstate carrier and vehicle snapshots among states.
We will connect to SAFER via our CVIEW
CVISN Level 1 ComplianceSafety Information Exchange
Implementation of the Commercial Vehicle Information Exchange Window (CVIEW) (or equivalent) system for exchange of intrastate and interstate snapshots within state and connection to SAFER for exchange of interstate snapshots.
We will implement a Wisconsin CVIEW for snapshot exchange within the state and connect it to SAFER
CVISN Level 1 ComplianceCredentials Administration
Automated processing (i.e., carrier application, state application processing, credential issuance, and tax filing) of at least IRP and IFTA credentials; ready to extend to other credentials [intrastate, titling, oversize/overweight (OS/OW), carrier registration, and hazardous material (HAZMAT)].
Note: processing does not necessarily include e-payment.
We will be deploying Polk’s COVERSnet application to provide automated processing of IRP and IFTA credentials.
OS/OW deployment is progressing, with limited self-issuance of permits now in production.
CVISN Level 1 ComplianceCredentials Administration
Connection to IRP and IFTA Clearinghouses.
We are connected to the IFTA Clearinghouse and we intend to join the IRP Clearinghouse
At least 10 percent of the transaction volume handled electronically; ready to bring on more carriers as carriers sign up; ready to extend to branch offices where applicable.
We expect to meet this volume. We are working with Polk to add EDI capabilities.
CVISN Level 1 ComplianceElectronic Screening
Implemented at a minimum of one fixed or mobile inspection site.
Ready to replicate at other sites.
We have a preliminary agreement with PrePass to implement their screening and clearance system at our Hudson and Menomonie SWEFs

Key Issues CVIEW and SAFER
Interface Specifications EDI vs. XML – we will attempt to decouple
and defer development of these pieces Polk COVERSnet software – standards
used and available functions
Electronic funds transfer and credit card acceptance
Key Issues State Requirements
State privacy concerns and conflict with open records – debate in legislature
Biennial budget process – money Technology Management Council prioritizes
projects – resources Ability to read non-PrePass transponders
would be dependent upon money and resources
Conflict between modal and non-modal divisions
Key Issues PrePass connections to state

Uniform Roadside ArchitectureIs It Worth Pursuing?
Is URA appealing from a technical point of view?
What impact would adoption of URA have on stakeholders?
Which forums would be appropriate for considering URA and developing specific standards?
