The primary reason for installing angled parking is to increase the available spaces. A positive byproduct of angled parking, sometimes, is traffic calming by narrowing the travel path. Parallel parking stalls typically take about 7 to 8 feet of the roadway width. On-street angled parking takes up at least twice as much, therefore less room for travel lanes. Of course, there are certain draw back with angled parking too, namely visibility, and how it may effect bike lanes in most situations. I designed over the years many angled parking layouts in the downtown and mid-town areas for the NTMP projects, and City’s “Angled Parking Program.” Working on these projects forced me to face some new challenges each time, due to varying geometry at each location. Also, there were issues with visibility and safety to consider. After a while, I thought there is need to formulate how we go about designing angled parking, and have a set of standards to show how we can address visibility and safety, while we maximize the space. The following illustrations are the result of my work on designing angled parking on tens of City blocks. Like it shows, there are two types of angled parking concepts, Front-in and back-in; both at 45-degree angle. It is possible to adjust the angled one way or the other, but I found the 45-degree angle to be the most common and the most efficient. While there are many types of parking regulation signage available, when it comes to the Back-In angled parking, not so much. Some other cities had come up with their own version of signs to educate drivers about this type of parking. I made a new version of the sign, and created also a new warning sign to be displayed together with the educational sign. With the evolution of the angled parking layout designs, came the placement of motorcycle parking inside parts of the hashed markings at the ends of the block. That idea prompted me to create a couple of new signs for motorcycle parking as well.
