TO IMPROVE ROAD and airfield, guidance, SAFETY, AND EFFICIENCY, key pavement markings MUST BE VISIBLE IN ALL WEATHERS and painted markings are NOT! lit LEDline® guidance safety lighting, is Visible In Any Weather so improves guidance, safety, and efficiency anywhere!
Lit LEDline® Guidance Safety Systems; Helps Increase The Safety And Efficiency of Roads and Barriers Especially In Bad Weather!
From the Above Video, The following Pictures Illustrate Just How Useful LEDline® Safety Guidance is
In Providing Key Driver Guidance In Bad Weather:
Notice: Because of the heavy sleet and snow, typical winter storm visibility in Ontario,
unlike the lit LEDline® safety guidance, there are NO painted pavement markings visible!
Below, the LEDline® safety guidance is clear and visible, but there are no other visible pavement markings! Indeed, visibility is so bad here, that even with the vehicle's headlights on and the red tail lights of the vehicle ahead lit, one can still hardly see the vehicle ahead!

Below was the visibility when the "daylight arrived".
NO one could see anything of the painted road markings!
(Note: In these daylight pictures of road visibility, the LEDline® safety guidance lighting was not installed in these sections of the road. If it had been, they would have been visible, as LEDline® is even visible in bright sunlight, never mind in these conditions).

Rain, Dust, sleet, and Snow Can Make painted Lane Line markings, reflectors and even signage, Impossible to See. at night, the lack of visibility of painted markings and lane lines in bad weather is even more of a problem for drivers! Visibility in all weathers, is why LEDline® safety guidance lighting should be considered for critical lane markings on difficult road sections. and, It is why LEDline® should be used for the lit lane lines at the high accident or potentially high accident areas, such as merging freeways.
The picture below is from the video above, and is a reminder that even with a vehicle's headlights full on,
sometimes there are NO visible road lane lines or other visible markings to guide one.
Here, all that one can see is the LEDline® safety guidance lighting, and, occasionally,
the vehicle ahead's red tail lights.
Visibility You Can Count On: Solid, Linear, LED LEDline®guidance safety lighting, are the only LED safety guidance Lighting Systems that melt snow without needing any additional heating elements!
From The Anchorage International Alaska Test:
Early Style Linear LEDline®, (with only 6 x LEDs) Melting the Snow.
(Note: Today's LEDline®, has 12 x LEDs and precision optics, embedded within the solid clear matrix).
LEDline® safety guidance lighting Road Usage:
Visible in all weathers, (it melts snow), LEDline® safety guidance lighting, helpS TO reducE accidents and is used for;
• highlighting in-road and barrier markings in any weather;
• nighttime highlighting and floodlighting the users of pedestrian crossings; • lit sign and in-pavement wrong way guidance safety lighting, directing and highlighting of the wrong way Access on roads and the wrong way access onto freeway ramps;
• traffic signal controlled in-pavement traffic guidance at complicated SPUIs or intersections; • lit in-pavement road signage; traffic merge arrows or Gore area outlines;
• for contraflow situations; lit MUTCD LEDline® safety guidance RPMs, highlighting no passing lanes when opposing traffic is using them;
• lit in-pavement traffic directional guidance at Roundabouts or other in-pavement road guidance applications; • highlighting road markings to reduce accidents, at repeat high accident sites.
• reducing traffic congestion in contraflow situations. • For rush hours; to safely Speed up accessing the spare capacity of the other side of the Chesapeake bay bridge, the Maryland Transportation Authority (mdta) will be Using in-pavement LEDline® safety guidance as lit rpms per the FHWA, MUTCD. • this lit, highly visible LEDline® safety guidance system, is used for marking and highlighting the crossover lane when oncoming traffic will be using the other side of the bridge's spare capacity. So, instead of employees having to physically put out and later collect guidance cones dangerously close to speeding traffic, these crossover lanes can be just switched on whenever they are required. • to improve the safety of employees and more efficiently use the spare capacity of the Chesapeake bay bridge for contraflow purposes to reduce traffic congestion.
When rush hour traffic congestion is much more congested in one direction compared to the other, there is unused spare road capacity on the other side of a bridge or tunnel. Using this spare capacity in the more heavily traveled direction is called contraflow and requires traffic to be using and traveling in the opposite directions on the spare capacity side of the bridge or tunnel.
Using in-pavement LEDline® safety guidance lighting there, as lit RPMs to mark the Chesapeake Bay Bridge contraflow lanes, can be done quickly, much more safely, and inexpensively, by highlighting the other sides of the bridge lanes infrastructure, when opposing traffic is to use the spare capacity there.
The cost of installing LEDline®'s safety guidance lighting system there is small compared to the safety and operational gains for the Maryland Transportation Authority (MDTA). Presently, when designating lanes for oncoming traffic for contraflow situations, the MDTA has to physically go out and hand-placed cones on a freeway. This is dangerous. Apart from the awful tragedy for a family, a single accidental death or severe injury can cost society more than +$5 million. Therefore, eliminating the need to send people out to physically place and then collect cones on the freeway, is a huge improvement for safety.
Using LEDline in-pavement safety guidance lighting means that there are huge savings in time and operational efficiencies when the oncoming traffic lanes can be designated with a flick of the switch. Therefore, LEDline® safety guidance lighting is far faster and much safer for employees, which translates into more safety, fewer costs, and more efficient Chesapeake Bay Bridge operations!

The Pictures Below are From Television, (so their quality is not the best),
However, they Illustrate the Sort of Magnitude and Potential Costs There of Having To Build More Bridges, or More Approach Freeways To Widening the Chesapeake Bay Bridges to Achieve More Road Capacity There. In Other Words;
The LEDline® Option Cost So Much Less!

Using LEDline® In-pavement Safety and Guidance lighting at The Chesapeake Bay Site, Is So Much Quicker; Less Cost; and More Efficient, As It Improves The Safety of Operations and Reduces The Time It Takes To Designate The Cross-over Freeway Lanes For Oncoming Traffic Use.
For contraflow purposes, Departments of Transportations (DOTs) use the spare capacity of the other side of a bridge or tunnel and its approach roads during rush hours, to increase the road's capacity in the rush hour direction during the rush hours. This is known as contraflow and is standard practice worldwide.
Presently, at the Chesapeake Bay Bridge, when designating lanes for oncoming traffic on the other bridge's spare capacity during rush hour, the MDTA has to hand-place cones on the freeway when designating these lanes for the traffic. This is not only time-consuming but more importantly, highly dangerous for their employees, who physically must drive along the freeway whilst placing the warning cones by hand when designating these contraflow cross-over lanes, all within inches of speeding traffic passing them. Subsequently, once the rush hour is over and the contraflow use of the other bridge's infrastructure is no longer needed, the MDTA employees have to again physically collect all the cones by hand with traffic speeding past them, which is again hazardous and highly dangerous.
As a way of improving the safety and the efficiencies of the operations at the Chesapeake Bay Bridge, using lit in-pavement LEDline® to designate the cross-over lanes in a contraflow situation makes sense, as, with a flick of a switch, a lit lane can be easily created. More importantly, safety for their employees is drastically improved, as no one has to go out onto the freeway to hand deliver and then hand collect all the cones with speeding traffic passing inches away from them.
From a driver's perspective, having more efficient operations to cross the Chesapeake Bay could help. Here the improved efficiencies of operations may help reduce traffic waits, and if it does, Maryland will be reducing the pollution, wasted gas, and wasted driver times, and, hopefully, reducing the frustrations created by the stalled traffic going nowhere.
LEDline® Being Installed as Lit Contraflow Safety Guidance for The Maryland Transportation Authority “Automated Lane Closure System”. By Eliminating The Need for Employees to Hand Deliver, Place and Then Later Collect Reflective Bollards and Cones to Create The Crossover Lanes to Reduce Traffic Congestion, LEDline® Improves Employee Safety, Saves Time and So Improves the Chesapeake Bridges Traffic Capacity.
Proof of LEDline® safety guidance lighting visibility in all weathers: the picture below is a Direct Visibility Comparison in deep snow at anchorage airport between; old Incandescent bulbed faa approved Airfield Taxiway Lights. (Note: These melt snow and ice because of the inefficient bulbs, which generate more heat than light ). and LED LEDline® Linear safety guidance visual aids. (Note: These too melt snow and ice without any additional heating elements, therefore, they are by far the most energy-efficient LED lamps!)
This Third-Party Picture, by Mr. Chas Triborn, at Anchorage International, is A Direct Comparison of LEDline®'s Safety Guidance Lighting Visibility In Deep Snow Compared To FAA / ICAO Approved Airfield Visual Aids.
Left: Is the old style FAA incandescent bulbed, (more heat than light), standard green taxiway in-pavement lamps.
Right: Is the old-style 6 x LED, (today's LEDline® has 12 x LEDs or more), in-pavement, yellow linear LEDline® lamps;
• both are highly visible in the deep snow.
• and, since both lamps melt snow, both are self-cleaning and remain visible in bad weather.
