MoDOT’s mission to provide a world-class transportation experience that delights our customers
                            and promotes a prosperous Missouri.

                                                                                             1
What is Smart Roadside?

 Using advanced technology as a tool in
 the roadside “toolbox” to improve
 efficiency and effectiveness of commercial
 motor vehicle enforcement operations.




                                          2
Why should you embrace
Smart Roadside?
 Targets high risk carriers;
 Provides an even playing field;
 Can be deployed at different sites (fixed,
 mobile, etc.);
 An opportunity to increase compliance
 verification when enforcement resources
 continue to be a challenge; and
  The increase volume of CMV traffic requires
 new methods to validate compliance.
                                                3
Missouri Quick Facts
 Plans, designs, constructs
 and maintains 33,639 miles of
 highways and 10,335 bridges
 and culverts.
 Has the most major river
 bridges (53) than any other
 state.
 The nation’s seventh largest
 state highway system.

What is so different in Missouri?

1. Use of Magnetometer Loop Detector
   (MLD) to “fingerprint” the commercial
   motor vehicle on
   the mainline. The
    loop is used for
   PrePass WIM with
   the addition of a
   mainline camera.

                                               14
How is the vehicle fingerprinted?

 Using the MLD, you can electronically tag
 and track CMVs based on the density and
 distribution of metal producing a
 waveform or “fingerprint” of the vehicle
 and its load.

 2. Attach weight data captured on the
PrePass mainline WIM for carrier vehicles
not enrolled in PrePass Program to the
vehicle’s fingerprint with an overview pic.

 3. Re-identify the CMV using a MLD loop
on the ramp along with a LPR, AUR and
Image Capture
system to identify
the carrier and
plate information
by querying the
state’s CVIEW.

4. The fingerprint of the vehicle on the
  mainline is matched with the fingerprint
  on the ramp. When a match is found, the
  weight and all information gathered from
  the LPR and AUR are put together.

5. The information from the Smart Roadside
   System (SMS) is passed to the lane
   control system and static scale software
   (Mettler-Toledo). If all the information is
   valid (no alerts) the vehicle is allowed to
   use the station’s bypass lane. All other
   vehicles are sent to the static lane. Lane
   control information is returned to the
   SMS system.

6. Eliminated the need for a PrePass
  Compliance Reader because the system
  will identify a vehicle enrolled in the
  PrePass system that was not identified on
  the ramp of the station if the vehicle
  received a red light and did not enter the
  station as required.

Bloomsdale Staffing

 Bloomsdale weigh station has 5 full time
 positions staffed by MSHP CVOs/CVIs.

 Open 7 days a week approximately 16 hours
 a day.




                                             27
Technology

 The new identification technology and
 scale platform system makes it easier to
 verify compliance and allows for better
 use of resources .

 The automated features, such as the
 automated lane control which closes the
 facility when traffic is backed up,
 enhances safety.
