For my transportation pre-assignment, I observed a site in Columbia, MD, specifically a suburban residential area near a park, a high school, and some businesses with a new two-way protected bike lane on one side. The protected bike lane is 9 feet wide in total, with 5 feet for one side and 4 feet for the other, and it is the only protected bike lane in the town with bollards. There are sidewalks along both sides of the road, but there are not crosswalks on every side of the intersection. Because the bike lane was new, I observed it on Bike to Work Day (May 19, 2023) from 7 am to 9 am.

My goal was to compare the vehicle type, vehicle vacancy, and road use to the infrastructure provided on the road during the morning rush, however there was no school for the public schools on this day. I calculated the types of vehicles used, as well the vacancy in each of them, whether they were missing the cargo they were built for or the passengers they were made to carry. Calculating this, especially which vehicles were driven by only one person with no cargo, could show how many of these trips could be potentially replaced with something more sustainable, like bikes. I also wanted to observe the recreational uses of the road, which would show how safe people feel using active transportation.
There were 1006 total vehicles in the two hour time frame, not including recreational uses of the road. 86.19% of them were cars, 11.53% were trucks, 0.80% were bikes, 0.70% were school buses, 0.60% were buses, 0.01% were taxis, and 0.01% were motorcycles. There were no pedestrian commuters. Most people were using a car to transport only 1-2 people, which is not a sustainable or efficient way to be transported. Despite the lack of commuter cyclists and pedestrians, 16 people felt safe enough to use the road for recreational purposes, but given the percentage of car use, they may use a car if they were going somewhere specific. Most of the trucks were carrying cargo, but a large amount were not, and there were many pickup trucks being used as if they were passenger cars, rather than to carry anything. This reflects the suburban stereotype of a bigger car as a status symbol, but is inefficient and unsustainable for actual transportation use.
This caused me to wonder why so little people are using more sustainable forms of transportation if there are only 1-2 people per vehicle. Specifically for the lack of bikes, I came up with some of these possible reasons:
- It was cold outside, which might not motivate people to ride, even on Bike to Work Day
- There was no school for public schools, which means parents might have taken the day off of work to take care of their children, and children were still asleep
- People might not know about the new protected bike lane, and they might already have other established routes
- Issues with the protected bike lane:
- It is very small for a two-way bike lane and seemed to have debris (sticks, glass, etc.) in it
- It is not connected well to businesses outside of this road, and is instead connected to parks and lakes, as if it was only built for recreational purposes
- A two-way bike lane can be inefficient, especially with one way getting a smaller lane; I saw people outside of the bike lane because they had to make a turn across the street, and things like that may discourage people who want to commute on their bikes but are worried about safety
- Overall, the bike lane is better than nothing, but it could use improvement
