SKIPPER: Speed devices will remain Speed bumps are here to stay

Why were they installed? NAS Jax has been cited in our past security inspections for not having "speed calming devices" in advance of our pop-up security barriers when entering the base. They are an additional measure to slow vehicles. Should someone run through both of the speed bumps, it shows intent to try and enter the base without authorization, and the pop-up barriers will be deployed as required by Fleet Forces Command instruction. To date, we have been unable to accomplish this due to the potential for serious injury or death as a result of the excessive speed of outbound traffic, which often far exceeded the posted 20 mph. The speed bumps now allow us to activate the pop-up barriers and minimize the risk of injury to outbound traffic. In the event that we have a gate runner, these barriers will now deploy in less than two seconds, so it is imperative that you never stop your vehicle on top of the pop-up barriers. Additionally, there have been several mishaps with vehicles speeding and hitting the concrete lane dividers while exiting the base. The speed bumps will likely reduce or eliminate these mishaps.

Why did you choose speed bumps? Although there were several alternatives available, due to the real estate restrictions at our gates, as well as fiscal constraints, the best available solution was to install speed bumps. In advance of installation of these speed calming devices, I met with representatives from Public Works, Security and Safety to discuss a variety of alternatives. Upon selection of the final design a review was conducted by the Surface Deployment and Distribution Command Transportation Engineering Agency, which recommended full-length paved speed bumps. However, this design was reduced to a less intrusive commercially available product, which allowed emergency vehicles to pass in a less disruptive manner.

Why is traffic now moving so slowly when entering and exiting the base? The primary reason for traffic backup is that many personnel feel the need to slow down to 1 to 2 mph to go over these speed bumps. This is not necessary. The manufacturer's design allows vehicles to travel safely over the speed bumps near the intersections of Allegheny at up to 20 mph, and traverse the speed bumps located by the guard stations at up to 15 mph. Another

complaint brought to my attention is that personnel exiting the base through the Yorktown gate cut into the right lane from the center lane near the guard shack at the last moment. Observations indicate that most of the drivers who did this had previously turned left off of Allegheny and did not have sufficient clearance to get into the right hand lane due to traffic. Therefore, they had little choice except to try and merge over if they wanted to make a right turn onto Roosevelt. However, it is important to note that the Commercial Gate is an authorized exit point until 5 p.m. These vehicles could go straight through the intersection at Yorktown/Allegheny and use the Commercial Gate to exit the base, which has very little backup. I encourage drivers to utilize the commercial gate for exiting the base in order to further distribute the outbound traffic flow.

What will happen when the new hangar opens in April 2009 and traffic increases even more? The base is presently updating our activity master plan. I have already asked for a traffic study to make recommendations concerning the new hangar traffic patterns as part of that plan. Pending that final report and any proposed recommendations, additional changes could be made at our gates.

Like any change, it will take some time getting used to the new speed calming devices. However, I am certain that with your cooperation and "safety first" attitude, the speed of traffic flow will increase and ultimately improve traffic safety aboard our station. Remember, you don't need to slow to a stop when traveling over the speed bumps and the Commercial Gate is an authorized exit point. In conclusion, one of my primary responsibilities as commanding officer is for the safety and security of the personnel who work at, as well as visit, NAS Jacksonville. I hope that you share my concern, as I take this obligation very seriously.
