Do You Know How Smart Our City Is Becoming?

Washington, D.C. is full of smart technologies, some of which you know about (apps such as Uber, Lyft, Google Maps, Bikeshare, etc.) and others you probably don’t. This past summer, I attended an event called Smart City Symposium- “Solutions for Business Growth and Economic Development” (include a small exhibition) in downtown D.C., hosted by the DC Chamber of Commerce and Verizon.

The Office of the Chief Technology Officer shared some of the technologies the city is already using. Further information on this can be found on their website.

But “5G Technology” was the key word through the whole event. For people who don’t know about 5G, it is basically 4G with user data. For example, Google will detect the amount of traffic by counting how many people are using their map at a specific location, same as they are tracking the restaurant rush hour by counting how many people are searching for it online.

Verizon is working to engage 5G technology in the D.C. area to make people’s lives more convenient. Here are some of the great products they demonstrated:

  1. Smart trash can

I was really impressed by this new trash can. They look like unimpressive boxes, but can fit four times more than a regular trash can. The smart part is that it can sense how full the trash bin is in real time and send a signal that it needs to be emptied, allowing garbage crews to come only as needed instead of on a set schedule, emptying bins that are not yet full. It can save time, resources, and energy emissions.

2. Home clinic

Home clinics are long-distance personal doctors. A doctor can talk with patients over video chat and then send devices the patient can use to measure their own vitals, such as blood pressure or blood sugar. After they know the patient’s health information, they can provide suggestions and prescribe medication. This will save patients time and money by allowing them to skip a trip to the doctor’s office if they have only minor symptoms and don’t need to go to hospital. The same methods can be used for other doctors, such as psychologists.

3. Agriculture drone

Agriculture uses more natural resources and has a greater carbon footprint than almost any other sector. Agricultural drones, however, will change the way crops are produced. Drones will gather information throughout the day on weather conditions like temperature, moisture, and wind. As more information is collected, the system will analyze the data and tell other devices how much water different crops need, if a certain action needs to be taken, and so on. This will significantly reduce resource waste and improve production.

4. Smart car

This program is similar to Zipcar, but it’s currently only implemented on some university campuses. It works like Car2go, where the customer can use the app to track where there has an available car. However, Verizon is still testing this technology so I do not have too much information about it.

From what I can see, 5G technology will save people time and help make life easier and more convenient. One of the downsides, however, is that I feel less secure because our personal information is publicized and stored on the internet. The internet will have information on where we are, what we are doing, and what we are talking about. I am excited about how the world is becoming more and more advanced, but I also want to be reassured that our information can be private. This is something people should keep in mind as these types of technologies become more prominent.

5 Ways to Help Traffic

In the midst of Tropical Storm Harvey, our hearts and thoughts go out to the families whom are affected by this storm. Due to its flat topography, Houston is well-known for its susceptibility for flooding. Many people woke up to find they were trapped inside their flooded homes and waited to be rescued. We wish the affected families the best of luck in their journey to recovery.
 
I have never been to Houston, but I have heard many stories about Houston’s traffic and planning. In this blog, I will share what I have learned from my perspective and my extended knowledge of transportation.
 
Houston is known for its sprawl. People tend to complain about the traffic because they drive to most of their destinations. The traffic is usually at a standstill.
 
Here is a video talking about the Houston’s freeway system.
 


 
American Highway Users Alliance published a statement that the Katy freeway in Houston was the second most congested road in America. Drivers spend a combined 25.4 million hours every year sitting in traffic on that road (which is 36 lifetimes worth). That is why the government decided to spend $2.8 billion to expand the road to 28 lanes, making it the widest highway in the world. Many people thought that this extra capacity would surely solve the problem. However, between 2011 and 2014, travel time on Katy freeway went up 55% (Meaning that driving between downtown Houston and Katyland, a 28-minute drive without traffic, takes an average of 64 mins during afternoon rush hour.)

Sounds unbelievable, right?

The video explains that the road expanding solution violated the fundamental law of roads: MORE LANES=MORE TRAFFIC. When the road got extended, more people used it, causing it to reach capacity again.

Here are some solutions for traffic as discussed in the video:
 

  1. Take public transit

This is always the long-term way to solve traffic. Taking the bus and light rail can definitely reduce the daily amount of traffic and is also environmentally friendly.

  1. Ramp meters

Meters on entrance and exit ramps can control the amount flow of traffic entering the highway. It slows down the number of cars merging onto the highway, ensuring traffic stays at its most efficient speed.

  1. Tolls

Tolls are a direct way to reduce traffic. In New York, which has high roadway tolls, people often prefer to take the train or subway into Manhattan instead of driving.

These fees can increase the overall cost of driving to a level where some people will decide the benefits of driving are not high enough and will choose alternative means of transportation.2005-03-13_15-53-32

  1. Roundabouts

Roundabouts decrease some of the worst type of collisions and still carry the same amount of traffic, according to study. Traffic tends to be smooth and consistent, albeit having a slower flow.

  1. Diverging diamond interchange (DDI), also called double crossover diamond interchange (DCD)
  • Fewer conflict points (14 for DDI, 26 for conventional)
  • Conflict points spread out throughout interchange
  • Better sight distance at turns
  • Virtually no driver confusion (FHWA study and new DDI observations in Springfield, MO)
  • Traffic calming features when desired
  • Wrong way entry to ramps extremely difficult
  • Shorter pedestrian crossings

In the DC metro area, commuters also face heavy traffic during the rush hours, especially in downtown DC, I-66, I-495, and I-395. After all, traffic is an issue for every major metropolitan area. We all contribute to solve this problem. I highly recommend everyone to take public transit like Metrorail, Metrobus, or the Capital Bikeshare.

A Little LEED Strategy for buying home

Home_LEED

Recently I’ve been studying for LEED Green Associate exam and the word “density” has been hanging in my mind, this is because “density” this word throughout the whole book. The very beginning of a project is ‘Location and Transportation’. This is a new category that was added to the LEED rating system. This category put more emphasis and attention on reducing one of the main contributors to global warming: transportation. It is clarified through the ideas of reducing the cost, pollution, and depletion of resources related to the daily transportation of people and goods to and from a destination. After reading Veronica’s post last week, it got me thinking about sustainability and how it applies to our daily lives, especially in choosing where to live. I think that LEED principles can be applied to a housing search.

The book divided Location and Transportation (LT) category into 4 points: Location, Transportation, Site Development, and Health and Livability. These points are often similar to what people consider when looking for a house or place to live.

Location:

Locate within a LEED-Certified Neighborhood Development

A LEED-Certified Neighborhood usually is a sustainable site. This is because the neighborhood has to meet the qualification of LEED requirements such as walkability, green infrastructure, floodplain avoidance, etc.

Located within proximity of surrounding density and diverse uses

“Density” is an important word in LEED. The reason behind this is to cut the distance shorter for people to travel to work or visit the building. Also, if the building is within walking distance (0.5 mile), people will not need to drive. Both ways would cut down on greenhouse gas emissions and will help reduce global warming.

 

Transportation:

Limit available parking

LEED-Certified buildings usually have limited parking, because this can encourage people to carpool or use alternative ways of travel.

Develop in areas that have multimodal transportation access

This could also inspire people to take public transportation modes like bus or rail.

Site development 

(This point is more for a someone building a home and their location selection)

Avoid developing on environmentally-sensitive land

This is for the sustainability environment. Considering the local bioregion, watershed, and community can help a project team minimize the sustainable features of the surrounding environment and to climate change. In LT category, sensitive land defines as farmland, floodplains, threatened or endangered species habitats, water bodies, and wetlands.

Locate the project on a pre-developed site

It would be an ideal area, because of the preexisting infrastructure is already in place. Pre-developed location can reduce the cost of installing new roads, sewer, and power lines.

Locate the project on a high-priority site such as a brownfield

A brownfield is a property that has the presence of hazardous materials, pollutants, or contaminant that may affect by redevelopment if the property. Remediation and development of brownfield can avoid land waste and reduce urban sprawl.

 

Health and livability

Develop in areas that promote walkability

Sidewalk and shelter for pedestrians should be provided, these make it easy for people to walk to and from the building for basic needs and routine functions.

Provide bicycle storage facilities, shower room, and bicycle networks in close proximity to diverse uses

This encourages the use of non-motorized modes of transportation.

Provide a bicycle maintenance program for employees or bicycle route assistance for employees and customers.

This could encourage people to ride bikes, walk, or run errands during the day. This can also decrease greenhouse emission caused by vehicle use and increase the health and welfare if building occupants.

 

Other factors recommended that contribute to this field that speak to “density” are the following:

Provide pedestrian amenities

Promote connectivity

Create a diverse community

Promote access to sustainable food

Provide access to grocery stores.

 

All of these factors would reduce a number of people who use their cars in their everyday lives. This will help contributing less greenhouse emission, at the same time, provide human more options to work out and revitalized neighborhoods.

Hope these points can help you, and Veronica, with your home location selection.
