<strong>Toll</strong> <strong>Facility</strong> <strong>Safety</strong> <strong>Study</strong> <strong>Report</strong> <strong>to</strong> <strong>Congress</strong><br />
Flexible Delinea<strong>to</strong>rs<br />
One opera<strong>to</strong>r uses flexible delinea<strong>to</strong>rs upstream of the <strong>to</strong>ll plaza <strong>to</strong> prevent severe lane changes.<br />
The delinea<strong>to</strong>rs are red and white and are moveable. They do get hit, but they are designed <strong>to</strong><br />
bounce back and only occasionally is there a problem with delinea<strong>to</strong>rs littering the roadway.<br />
Cones<br />
One opera<strong>to</strong>r reported using cones <strong>to</strong> separate directions of travel at the plaza. Orange cones are<br />
used because the <strong>to</strong>ll facility has reversible lanes. The opera<strong>to</strong>r reported that the cones do not get<br />
hit often because traffic is typically slow through the plaza, but there are problems with the color<br />
fading due <strong>to</strong> ultraviolet exposure.<br />
Advance Signs<br />
All opera<strong>to</strong>rs use advance signs <strong>to</strong> warn drivers that they are approaching a <strong>to</strong>ll plaza. Sign<br />
messages frequently include TOLL PLAZA AHEAD, PAY TOLL AHEAD, etc. In addition <strong>to</strong><br />
these warning signs, some opera<strong>to</strong>rs are also using lane designation signs in advance of the<br />
plaza.<br />
One opera<strong>to</strong>r uses two advance signs <strong>to</strong> get drivers in<strong>to</strong> the proper lane and then drivers receive a<br />
third lane designation sign overhead at the plaza. Personnel report that the addition of these<br />
signs seems <strong>to</strong> have decreased the weaving of traffic at the <strong>to</strong>ll plaza.<br />
Another opera<strong>to</strong>r uses advance lane designation signs, but its signs are more unique. After<br />
departing the plaza, drivers can either take an Interstate or exit on<strong>to</strong> a local road. The advance<br />
signs direct drivers <strong>to</strong> the side of the <strong>to</strong>ll plaza where they will need <strong>to</strong> be depending on their<br />
direction of travel downstream of the plaza. The opera<strong>to</strong>r reported that since installing the lane<br />
designation signs, there has not been one accident downstream of the plaza.<br />
A few opera<strong>to</strong>rs reported that the issue of <strong>to</strong>o many signs has been a problem for them as drivers<br />
become overwhelmed and do not see anything. One opera<strong>to</strong>r reported excessive signs as a<br />
problem, but commented that none of the signs could be removed because the facility is at a<br />
border crossing where extra signs are necessary.<br />
<strong>Toll</strong> Plaza Approach Warning Devices<br />
An innovative strategy reported by one agency was the installation of white strobe lighting on<br />
the canopies at all <strong>to</strong>ll plazas <strong>to</strong> highlight facilities in inclement weather. The opera<strong>to</strong>r reported<br />
that the strobe lighting has definitely helped drivers in foggy driving conditions.<br />
The same agency reported using maintenance trucks with flashing lights and qualified flagging<br />
personnel at the rear of traffic back-ups when the traffic volume stretches beyond sight of the<br />
plaza. This technique is used <strong>to</strong> prevent rear end collisions at the end of the queue.<br />
<strong>Safety</strong> Programs<br />
One opera<strong>to</strong>r initiated a <strong>Toll</strong> Plaza <strong>Safety</strong> Awareness Program. This is a month-long program<br />
that runs twice a year. The opera<strong>to</strong>r has its own dedicated police force, and <strong>to</strong>gether with the<br />
State Police, they run the awareness program. Police perform various operations at the <strong>to</strong>ll plaza<br />
including seatbelt checks and ETC speed enforcement. Additional signs, such as portable<br />
changeable message signs, are used as needed. The opera<strong>to</strong>r reported that <strong>to</strong>ll operations are not<br />
negatively impacted and the program seems <strong>to</strong> have a short-term affect on negative driver<br />
behavior.<br />
