Road construction is rarely an ideal place for anything. It’s unsafe for workers, it causes traffic issues, and nearby businesses can suffer from it. One more thing can be added to the list, as self-driving cars are also having a hard time navigating construction zones, as well.
For technology companies, like those working on self-driving cars, coding in a static environment can be easy. But, throw a constantly changing and non-standardized situation at them and things can get infinitely more complicated. There are many cues on highways that generally look the same, like mile markers, speed limit signs, stop signs, and road markings that autonomous vehicles rely on to navigate. When road construction is introduced, however, things are not so cut and dry. There are a variety of different ways that workers can sign and barricade construction zones and those variances are causing issues with coding, according to Wired.
From December 2015 to November 2016, self-driving car companies have gathered data regarding what caused crashes and what caused the humans to have to take control of the vehicle. Construction zones were reported to be one of the more common reasons that humans had to take control. As Wired points out, a large majority State and local DOTs also do not have a database that shows where currently active construction sites are. Having a reliable database would allow the cars avoid those areas all together.
There are some possible solutions, however, but they will require a lot of work. The construction zones aren’t really a huge problem for cars that still having a steering wheel and pedal, as long as someone is physically able to operate it. For those who cannot, or in cars that don’t have a steering wheel or pedals, some companies are planning to open call centers to help the car navigate around trouble areas.
Another option uses short range communication technology to allow the cars to speak to each other which could alert other cars of a hazard up ahead. According to Wired, “the National Highway Safety Administration plans to mandate that all new cars come equipped with this ‘talking’ tech by 2020.”
While not directly a problem for the construction industry to solve, as self-driving technology becomes more and more viable, some changes will probably need to be made. After driving in different states around the country, it’s clear that standard practices for signage and barricades need to be addressed and enforced, but it’s unclear exactly how that should happen.

Almost two years after they announced the release of their Bluetooth Battery that allowed owners to remotely monitor battery life and even disable the battery if it’s stolen, DeWalt is set to release a massive upgrade to their connected tool platform.
There’s no shortage of company’s trying to improve the world’s roadways. Asphalt and concrete each have their own disadvantages, especially when maintenance environmental factors are taken into consideration. Plastic is a major problem for landfills, as well, as it can take an estimated 500 years to fully decompose. One UK company believes they can solve both maintenance and environmental problems through the use of recycled plastic.
Feeling the pressure of 9 straight quarters with a decline in total revenue, Caterpillar has acquired the equipment sharing startup, Yard Club, to get help dig themselves out of the dirt. Their most recent quarter was the company’s first positive revenue quarter since November of 2012.
I’m a firm believer that before robots start taking over construction jobs, we’ll first be working with robotics to make workers more efficient and our job sites more functional. Instead of using 3D printing robots to build an entire project, why not use them first to create intricate details and bring character back to buildings? Instead of pushing human labor out of the way, why not use robotics to enhance the abilities of our workers, to improve their health and productivity? With rise in development commercial exoskeletons, workers will soon be able to harness additional strength by just slipping on a suit.
Last year, Tesla announced a new disruptive product to the market in the form of solar roof shingles. Unlike traditional solar roof panels, these shingles mimic the look of traditional terra cotta, clay, and slate tiles, creating a more aesthetically pleasing look. This week, the company began taking pre-orders for the roof shingles and also released a cost calculator.
The Massachusetts Institute of Technology (MIT) is constantly researching ways to improve construction process and materials, like this material 10 times the strength of steel, or this solar cell that’s lighter than a soap bubble, or this “reversible concrete.” This time the Institute is showing off its autonomous robot that can spit out building structures on site within hours.
Tracking employees instantaneously is a dream scenario for employers. It gives them tons of data to analyze to determine where money can be saved and where resources can be placed to be most efficient. The struggle is convincing the employees that tracking their every move is not going to get them in trouble or fired. There’s a balance in there somewhere and that’s the challenge facing both employers and tech companies right now.
Two of the most critical concepts of construction safety are the ability to see what you’re doing and to also be seen by others around you. Construction workers rely heavily on their employer providing lighting systems when working in low light conditions, but those systems are not always adequate.
There’s no doubt that the construction industry is behind when it comes to technology, but things are beginning to change. In the past few years, our industry has seen millions of dollars poured into new technology, including smartphone apps, advanced construction materials, and advanced safety equipment. One of the struggles –and perhaps the main struggle- with introducing new technology to the field staff is that many of them have been managing their jobs the same way for a long time. It can be difficult to convince them to change, especially if they have been successful with their current process.
