Engineering Division

The Engineering Division is responsible for the following activities:

  • Perform engineering, surveying, and design of City water, sewer, pavement, sidewalks and other projects as needed.
  •  Maintain records, create bid documents, project plans and maps of City Infrastructure.
  •  Review and approve private construction site plans for site grading, drainage, storm sewer, storm detention, sanitary sewer and water.
  •  Inspect work on City projects, private construction projects, and in the City Right-of-Way for compliance with City standards and specifications.

Pedestrian Hybrid Beacon (PHB)

Due to the amount of pedestrian traffic crossing East Wooster, the Ohio Department of Transportation (ODOT), City of Bowling Green, and Bowling Green State University conducted a joint safety study funded by ODOT to determine if more crosswalks were needed. As a result of this work, four additional crosswalks were recently installed – also funded by ODOT.  Two of these locations feature pedestrian hybrid beacons (PHB) – one across from Founders Hall (east of Troup, near BGSU Lot Q) and one at the Stroh Center.

A pedestrian hybrid beacon is a pedestrian-activated warning device located on the roadside or on mast arms over midblock pedestrian crossings. The beacon consists of three lights – 2 red lights over 1 yellow light.  The beacon is dark until a pedestrian hits the activation button, at which time the yellow light will begin blinking followed by a solid yellow light – alerting motorists to prepare to stop.  Solid red lights will then be displayed telling drivers that they must stop while pedestrians cross.  Once the red lights begin to blink, motorists may proceed if the crosswalk is clear of pedestrians.  At the conclusion of the lighting sequence, the blinking red lights will stop and the beacon will go dark again.  The entire interval at both locations will be programmed to last approximately 30 seconds.

Roundabout Information:

  • How are roundabouts safer?

Roundabouts are designed to be safer and more efficient than a traditional intersection.  The design of the roundabout creates a low speed (20-30 mph) environment and prevents high angle crashes such as “T-bone” crashes.  Low angle, low speed crashes tend to be less severe than higher angle, high speed crashes.  – Reference: ODOT

  • Are roundabouts really more efficient?

Yes. Vehicles are able to move more quickly through the intersection because of the “yield at entry” – drivers only have to watch for traffic from the left, and if there is an adequate gap available, they can enter the intersection without stopping.  Once in the roundabout, drivers have the right-of-way, so they will not have to stop or yield to exit.  If the driver does need to yield at entry to traffic inside the roundabout, their delays are brief and typically less than the time they would have been delayed at a traffic signal.   – Reference: ODOT

  • How does the design compensate for large vehicles such as semi trucks?

Incorporated into the design of roundabouts is something called a “truck apron.” The truck apron is the area between the central island and the roadway that is mountable by larger vehicles but not used by passenger vehicles.  Typically this area is concrete versus the roadway which is asphalt.  – Reference: ODOT

  • How much safer are roundabouts?

According to the U.S. Department of Transportation Federal Highway Administration, roundabouts reduce the types of crashes where people are seriously hurt or killed by 78-82% when compared to conventional stop-controlled and signalized intersections, per the AASHTO Highway Safety Manual.  – Reference: USDOT
