Smart Roadside Virtual Weigh Station Project

Report
Missouri’s
Smart Roadside Program
Michelle Teel, P.E., PTOE
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.

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.
17

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.
