Bike Repair Stations

Bike Repair StationFortunately for bicyclists, public agencies are not only installing more bike trails, lanes, and shared use paths. Over the last few years many are also recognizing the need for support facilities and adding bike repair stations along these routes. The Fixit station shown in the photo above has an air pump to the left and a bike mounting/repair station on the right. This specific type of station includes the following tools which hang inside the station to assist in repairing your bike – a close up of these tools is shown below: Bike Repair StationTools

  • Philips and flat head screwdrivers
  • 2.5, 3, 4, 5, 6, 8mm Allen wrenches
  • 8, 9, 10, 11, 15, 32mm box wrenches
  • Tire levers (2)

This specific model, made and sold by Dero, is available in three styles and in many different colors and finishes including galvanized, thermoplastic, and powder coated. Their website offers CAD drawings, specifications, and other information. The company also publishes a map showing where their stations have been installed which might be helpful to bicyclists who are planning their routes. According to the map, bike repair stations have been placed in North and South America, Europe, Australia, and New Zealand. The company also offers other useful bicycle support structures such as shelters, lockers, racks, and signage.

Some agencies such as the Ventura County Fire Department (VCFD) have adopted an innovative idea of installing these stations at their own facilities. VCFD is taking advantage of National Bike Month to launch the installation of 16 repair stations at fire stations across the county. And they are hosting a Bike 'n' Ride event to celebrate. You can read more about the department's innovative support of their cycling community in this article in the Camarillo Acorn: "Fire stations across county to add bike repair services."

Real Time Weather Mapping with mPING

mPING weather display

mPING, a real-time weather application, offers interactive insight into what is really going on with the weather in any location around the world. Users can access the app to either anonymously submit reports of current weather at their own location or view reports from others by downloading the app from iTunes or Google Play. All reports are shown through a repeating display over a specific time frame with an icon designating the specific type of weather such as rain, drizzle, snow, flooding, wind, and hail. The same map of the reports can also be accessed online at the mPING website. The image above is a screenshot from the mPING website of recent weather in the midwest. 

The app was launched in 2012 by developers from NOAA’s National Severe Storms Laboratory and University of Oklahoma and the Cooperative Institute for Mesoscale Meteorological Studies to assist in fine-tuning weather forecasts. According the the NOAA website, NOAA National Weather Service (NWS) forecasters can access the reports on their office workstations. This allows them to "overlay mPING reports with other data such as radar and satellite observations to aid them in their decision-making." Also the site reports that "television stations and private weather companies have the opportunity to build the ability to submit and display mPING submissions in their own branded applications, making the information available to the public in new ways."

Some tips to keep in mind while viewing the map:

  • The time frame displayed is over a three-hour period, and the time clock in the upper right corner is set to Greenwich time. (As an aside, per the NWS website: "All aspects of meteorology are based upon a world-wide 24-hour clock called Zulu time (Z), more commonly called Coordinated Universal Time (UTC). You will notice all weather maps, radar, and satellite images all have their time expressed in "Z". The Zulu term stems from military usage while Coordinated Universal Time is the civilian term for this 24-hour clock.")
  • You can start and stop the play of the weather reports by clicking the play/pause button in the upper right. This is the top button in the vertical line of three buttons located under a layer button.mPING menu buttons
  • A legend for the icons can be found by clicking the middle button in the vertical line of three buttons located in the upper right of the screen. Below is a screenshot of the legend which will slide out after clicking this button. This legend also shows the type of reports which can be submitted. (Click the image for a higher resolution view.)mPING Icon Legend
  •  The bottom button in the vertical line of three buttons can be used to turn on and off the history of weather. Turning it on means that over the three-hour display all weather events will remain showing in the display. Turning it off means that as the weather plays out over the three-hour time period shown, you will only see weather reports at the time they were reported.
  • The layer button at the very top of the upper right of the screen allows the user to change to a topographic background instead of the black default background shown here.

2017 National Engineers Week Educational Resources

An increasing number of STEM professionals have been flooding the market for the last decade, yet in the next ten years there will be a shortage of professionals in the field. The U.S. Bureau of Labor Statistics estimates that from 2012 to 2022, STEM employment rates will grow by 13%, higher than the 11% projected growth across all other occupations. And yet by 2025, the U.S. will need approximately one million more professionals than it will have produced.

Engineers Week is one step towards a solution to this conundrum. The 66th Engineers Week, which started on February 19th, is being celebrated in schools across the nation. With new initiatives such as the Future Cities Project and Girl Day, Engineers Week aims to inspire the next generation of engineers who will help steer the U.S. as a global leader in the fields of science, technology, engineering, and mathematics. Below you will see a number of academic infographics that showcase how the future generation of engineers can impact the world.

From 7.4 billion in 2016 to 9.7 billion in 2050, the world's population will continue to grow over the next decade, and the brunt of the baby boom will be centered around developing countries. The problem is that these same regions do not have sufficient infrastructure to cope with the rapid growth.

The challenge to bring basic infrastructure to the developing world now falls on the shoulders of the next generations of engineers. By having a STEM expertise, it will not only put them in the forefront of science and technology, but it provide them with the skills to steer the world towards a better future. To learn more about engineering infrastructure for the developing world, check out the infographic below created by Norwich University’s Online Master in Civil Engineering program.

Technological advances in transportation and information technology have resulted in a global tourism boom in recent years. The good news: the economies of both leading and emerging destinations have been positively impacted. The bad news: the rise in coastal tourism is taking a toll on the environment. The silver lining: the continuing surge in global coastal tourism has indirectly caused more demand for environmental engineering professionals.

Indeed, the next generations of environmental engineers will have to propose and develop sustainable coastal tourism solutions that aren't focused on doing the tourists a favor — they're literally saving the planet, one tourist destination, coast, and reef at a time. To learn more about how engineers can help build sustainable coastal tourism, check out this infographic below created by Ohio University’s Online Master of Science in Civil Engineering program.

Roads, bridges, and other critical infrastructures are the hallmarks of modern civilization. The bridges of today are not only a testament to the cultural aesthetics and norms of the period, but also the technological prowess of society.

However many of our bridges are crumbling and scouring due to several causes. We need a new generation of engineers to not only preserve the architectural symbols of our culture, but also adopt a modern approach to the renovation of existing bridges and planning of new ones. These engineers are ensuring the safety of the people using the infrastructure today and a century from now. To learn more about engineering strategies that prevent bridge failure, checkout the infographic below created by the New Jersey Institute of Technology’s Master of Science in Civil Engineering Online program.

3D Printing for Civil Engineers

3D Printer

Lately I've been thinking our field might be missing out by not exploring the opportunities offered by 3D printing. Even though 3D printers have been around for many years, I haven't seen anything significant related to its use by agencies or firms in our field. I remember a 3D printer in use in a classroom at the college where I used to teach and that was at least 13 years ago. But that printer was used by the mechanical drafting students – not those in the civil technology field. So my partner and I have embarked on the goal of learning more about 3D printing and how the technology can be used in the civil engineering field.

Fortunately we found a learning program hosted by the University of Illinois in Champaign-Urbana which also happens to be our alma mater. The program is offered through Coursera and is a series of 5 courses leading to a specialization certificate in 3D printing. We began the first course right at the start of 2017 and are almost finished with the second one. So far the content has provided a good introduction to 3D printing and offered ideas about how it has been and could be used in many different fields.

Near the end of the second course, we were introduced to Josh Ajima, a teacher in Northern Virginia. In his presentation, he described how he created 3D representations of the earth's topography to visualize how different areas of a watershed relate. A description of his work with fabricating the Chesapeake Bay Watershed can be found in his article, "Design Challenge: Chesapeake Bay Watershed." Civil engineers can see right away how 3D printing an area's topography can lead to better understanding of watersheds, flooding impacts, material transport, and other related concepts.

Then, in our effort to learn more about the local 3D printing community, we attended a workshop at the Maker Lab in the Harold Washington Library in Chicago. There we saw a printout of the topography of the bottom of Lake Michigan. We were also introduced to the idea of using 3D printing to display data. An example of this type of use can be found on a 3D printing site called Thingiverse where the user anoved has uploaded a model of the United States to be used to visualize data sets for the states. A screenshot of anoved's Thingiverse page with the map is shown below. We can imagine an agency using this model for public education to show the amount of transportation funding spent by each state or the number of highway fatalities or miles of roadway.

Thingaverse Example of US 3D printed map with data

I'll continue to share our experiences with 3D printing as we learn more about the technology and increase our understanding of how it might fit into civil engineering. In the meantime, if you are interested in learning more, I'd encourage you to check out the classes on Coursera – they are free to take if you are not interested in earning a certificate for the specialization. You can also visit Maker Labs in your own areas – they are usually found in most larger cities, particularly in libraries. Also, if you know of any uses of 3D printing in our industry, we'd love to hear about them – just drop us an email, comment below, or reach out to us on social media.

Mapping the Accessible Path

Access map screenshot showing sidewalk steepness at 0.5%The Data Science for Social Good (DSSG) team, a group out of the University of Washington, has been involved in an effort to improve mapping of the pedestrian way. By making use of the work from the OpenSidewalks project, they created AccessMap – a trip planning tool for people with limited mobility. With this tool, people can find the most accessible path through a network of sidewalks connected by curb ramps and street crossings.

At this time, the tool has only been implemented in Seattle, but the group plans to expand to other locations. The data used for the project is a compilation of the following elements with sources noted:

  • Base map – OpenStreetMap (OSM)
  • Sidewalks and curb ramps – Seattle Department of Transportation
  • Street crossings – DSSG Team
  • Elevations – National Elevation Dataset, USGS

When a user clicks a sidewalk segment, the steepness or grade is displayed. The screenshot of the map above shows a sidewalk segment along 1st Avenue between Madison and Spring streets at a 0.5% grade. Sidewalk segments are also colored coded to indicate the grade with red exceeding the required 5%, yellow just below the requirement, and green meeting the requirement. Clicking a street crossing or crosswalk displays the steepness or running grade along with a "Yes" or "No" to indicate whether or not curb ramps are at the corners.

To plan a route using the map, the user types in their origin and destination in a manner similar to how other mapping programs work. The difference is that Accessmap has a drop down tool for the user to designate a limit for maximum uphill and downhill grade and the need to avoid construction and require curb ramps. Different mobility assisted devices such as wheelchairs or canes can also be designated. Below is an example of a planned route.
