What’s an activity that weathers rain, snow, and tornado warnings to piece together an accurate story of how a city curbside is being used? It’s what I specialize in, and one of the most important steps to making good engineering and planning decisions: data collection. The importance of collecting holistic and trustworthy data cannot be overemphasized as cities seek to manage growing demands facing our curbs.

The Role of Data Collection in Curbside Management

Curbside space is a hub of competing transportation modes. Delivery trucks need space to pull up to drop off a package; cyclists and e-scooter riders need safe lanes to pass parked cars; drivers want to find the spot closest to their destination. Every block face has a unique set of users and needs, which means block-by-block data collection is required to understand how that curb is being used, how cities can regulate it for better safety and efficiency, and how it fits into the regional transportation network.

Transportation Planning Challenges With Curbside Data Collection

The biggest challenge facing curbside data collection lies in the number and variety of data points collected. The lack of standardization across agencies is an additional challenge to collecting comprehensive curbside data. Curbside management is also becoming increasingly automated, but manual effort done by an actual person is still required. In turn, this makes it an employee management exercise as well as a data collection exercise where both parties work in tandem.

How do we collect curbside data? The process is more complicated than simply capturing how many vehicles use a space in a day and how quickly turnover occurs. The nuances of the collected data tell an important story about who is using the curb and their behavior patterns. We get that information from the make and model of each vehicle, what state the tag was from, whether or not the vehicle is registered, if there is a handicap placard in the window, and, in special cases, where approval has been given by the governing DOT. It is impossible to capture detailed data without having people on the ground supplementing the technology with human judgment, and filling in the gaps in the story.

Make the Distinction Between Rideshare Vehicles and Common Cars

Another interesting challenge is distinguishing normal vehicles from rideshare vehicles. More and more, agencies want to understand how rideshare vehicles are using curbsides to pick up and drop off passengers. The distinction is made, of course, through capturing the decal on the car, but it’s difficult to do this consistently because not every car visibly displays their decals, which requires action from the rideshare companies.

Select a Data Collection Partner that Understands Curbside Management

Before jumping into data collection, you first need to understand how you plan to use it. Look for a company that has experience with the specific type of data you want to collect, and who is willing to put in the work to assemble a customized plan for getting you the information you need. A company that understands and utilizes new data collection technologies, but knows how to supplement the automated processes with human judgment and fact-finding. As data collectors, we’re detectives, and each case warrants a unique approach to understand curbside usage from every angle.

Strategize and Avoid Collecting Too Much Data

Of course, curbside data studies quickly become inefficient and costly when too much collection is performed manually, which is where technology comes in.

One of our most successful approaches to curbside management has been using a GoPro GPS camera strategically placed to capture a large amount of data in a small amount of time. We can rewind, stop, or go back and collect additional info our client needs. Using the video, we have done everything from sign inventory and occupancy to turnover and general observations. Data collection is like assembling a puzzle. However, experiencing even the practical details is the best way to learn from it.

Qualiy Counts performs curbside data collection

Data collection is like assembling a puzzle, and experience can be the best teacher; even down to the practical details. For an example, we played a role in the parkDC: Penn Quarter/Chinatown project in Washington, D.C., which captures and predicts occupancy using a blend of data sources that eliminate the need to put a sensor in every parking space. We needed to simulate vehicles looking for parking around the Capital One Arena, so not thinking, we rented a set of bicycles to do the collection. Well, after about three hours of riding up and down the hills of D.C. and continuous stop and go, we realized it was necessary to switch to electric bicycles. Needless to say we learned a valuable lesson that day! (Overall, we were proud to support an effort that resulted in a 15% reduction in time spent looking for a spot during all time periods on weekdays and weekends. You can read more about it here.)

Build in Time for Data Collection and Curbside Analysis

Simply put: good data collection takes time. Technology makes the process more efficient, but the manual elements of the work can be cumbersome. We need time to come up with customized strategies for our clients and implement them thoroughly by not rushing through the process and missing key data points. One of the best things project managers can do is understand the time-intensive nature of curbside data collection, and plan for it.

How Data Improves Curbside Use – ParkDC Neighborhoods Case Study

After the success of the parkDC: Penn Quarter/Chinatown pilot, Quality Counts partnered with Kittelson and Gorove/Slade to support DDOT in parkDC: Neighborhoods. To help DDOT respond to parking-related neighborhood concerns, we surveyed 110,000 vehicles in 2,300 block faces in five District neighborhoods.

We collected two types of data: occupancy data (parking occupancy by block), and vehicle data (type of vehicle, license plate state and number, and the display of residential/visitor parking permits) for every vehicle parked on the street. Essentially, this data helped DDOT either confirm or disprove hunches about who was taking up the most parking space. DDOT had a fact-based response to questions and issues raised from the public, and the data helped inform parking policies, including the location of loading zones and accessible spaces.

A crucial technology with that project was the ability to use a GIS-enabled map and cell phones to collect our data and have it automatically populate the database. Additional coordination was conducted to ensure counts were completed while school and Congress were in session, and the U.S. Secret Service, Capital Police, Metropolitan Police, and other government agencies in D.C. were informed in advance of the counts to minimize disruptions.

We faced our fair share of storms during this process. We collected data in the rain and snow, and had to cancel a day as we were collecting during a tornado warning. We used plastic bags and heat pads to protect our employees and equipment, but some days it was about knowing when the weather was just too much. In total, however, we were able to collect vehicle type data on 360% more block faces than we were originally scoped to collect because of our customized interface.

Using lessons learned from the data collection efforts, Kittelson helped DDOT develop guidance for future data collection efforts, and DDOT now has a mechanism for collecting updated vehicle data using in-house staff for additional neighborhoods in Washington, D.C.
