Enclosure Design / Equipment Install by Gannett Fleming

System Components Cohda MK5 OBU

‒ Communicate with other road users Cohda MK5 OBU firmware (Significant

modifications)‒ Developed to generate and process work zone messages

Cisco IR809 router (No modifications)‒ Connects the OBU to the PTC server

PTC Server (Minor modifications)‒ Enhanced to provide customized messages for retrieval

by Waze Waze service and smartphone application (No

modifications)‒ Waze will need to poll more frequently

Evaluation Vehicle Configuration

Evaluation Vehicle included:• Cell phone equipped with Trip Talk• Ipad running Waze• Cohda MK5 OBU with antenna• Dashboard camera• Laptop with wireless internet access

• Configured to pull data from Cohda unit located on Evaluation Vehicle and Maintenance Vehicle

Operational Evaluation MemorandumSystems Engineering Process – Were the needs met?

Number Needs from Concept of Operations Need Addressed

(Y/N)

1 Maintenance and construction operations need to be able to inform the driver of upcoming work zones, and

Y

1.01 inform the driver of reduced speeds, Y 1.02 inform the driver of lanes affected N 1.03 inform the driver of delays N 1.1 Information needs to be delivered to drivers in or near the work zone

(within 0.1 miles) Y

1.2 Information needs to be delivered to evaluation staff in OBU-equipped vehicle(s) in or near the work zone (within 0.1 miles)

Y

1.3 Drivers need to be able to receive messages through the Waze commercial smart phone application and TripTalk application for stationary work zones and

Y – only TripTalk

1.31 Receive messages for mobile work zones Y 1.4 Drivers receiving information via Waze and TripTalk regarding mobile

work zones need to receive the information prior to reaching the active work zone area

Y – only TripTalk

Pilot Findings Initial implementation handles vast majority of work zone

situations correctly CV-DSRC stable platform for providing near real-time moving

vehicle/ work zone status CV-DSRC-based system reliably provides data for use by

mobile phone travel apps CV-DSRC can be integrated with commonly used wireless

gateway for wide area communications Cohda OBU powerful Linux computer

‒ Capable of mapping applications not included in pilot Lesson’s learned interfacing with Waze

27

Pilot Findings Installation approach (system on when ignition on) highly reliable

‒ No human interaction needed to turn-on system Very few vehicles on Penn Turnpike are currently equipped with

CV-DSRC‒ 2 on PTC‒ 2 on nearby roadways

Grounding issues with Cisco Router. ‒ Replaced twice during the pilot

Need to evaluate design trade-offs with regard to work crew intervention‒ More sophisticated logic required for some situations

• Maintenance vehicle on overpass• Maintenance vehicle in nearby service area• Maintenance vehicle reversing to stop
