The following conclusions were reported: 1. Advantages and disadvantages. The motorists are provided increased visibility once they are ready to exit or leave the parking space when utilizing the reverse angle concept. Oregon Department of Transportation Traffic Management Section Traffic Engineering Services Unit March 15, 2001 Safety Comparison of Angle and Parallel Parking File Code: TRA 07-01-05 SUMMARY Recently, the Traffic Engineering Services Unit was asked to review the research on the safety differences between types of on-street parking, specifically parallel and angle parking. Angle parking is similar to perpendicular parking, except the cars are aligned in an angle. This is true, provided that adequate widths for travel lanes are available. But in great part the decision is more based on road width constraints than anything. A 60 degree turn is easier to pull off than a 90 degree turn, so parking lots like this are less likely to see people moving back and forth trying to fit into spots. Reverse angle parking, also known as “back-in angle parking,” is just like diagonal parking except you enter the space by backing into it instead of pulling forward. The attendee holds on to the keys of all cars. By Bryant Ficek, PE, PTOE. Pros & Cons of Back-In Angle Parking. When making the decision, it really depends on preference, location, and the availability of space. better view of the roadway for leaving, and better angle for faster switching from parked mode to traffic mode. The angle parking is a compromise solution. If one needs to get out and it’s block by another car, the attendee simply brings the keys to both cars and moves the car that blocks the other. Reverse angle parking is simply parking at an angle in reverse so that the backend of the vehicle is closest to a sidewalk or the front end of the vehicle will exit the parking slot first. Normally the angle is aligned with the direction cars approach the parking space.
Advantages of back-in angle parking over parallel parking include eliminating the risk of drivers clipping a bicyclist with their door as they leave their vehicle. But instead of pulling forward into the space, drivers back into the angled stall. But instead of pulling forward into the space, drivers back into the angled stall. The caption of the picture reads “Angled parking can be more efficient than 90-degree parking.” In both figures the parking lot can accommodate 80 cars. These parking spaces still require a decent amount of turning to enter into, and thus require two lanes of parking traffic, but they help make space for those lanes with their angled design. Back-in angle parking is a relatively new concept starting to be seen in more areas. 2.0 REVIEW OF LITERATURE In general, the results of the literature review indicate both advantages and disadvantages of parallel and angle parking on city streets. Back-in angle parking is a relatively new concept starting to be seen in more areas. According to the Pedestrian & Bicycle Information Center, back-in angle parking provides motorists with better vision of pedestrians, bicyclists, motor vehicles, and other road users as they exit a parking space and enter moving traffic. It makes it a lot easier to drive into the parking space in contrast to perpendicular parking, where the parking space is at a 90 degree angle. Flat-angle parking does not adversely affect the safety or capacity of travel lanes when compared with the generally accepted arrangement of parallel parking. It’s a different situation than on-street, because in this situation the cars are parked by attendees (or valets).

In this situation, double parking is used to be able to park as many cars as possible in the parking garages. determine the advantages and disadvantages of angle parking in comparison to parallel parking. fered advantages over typical angle parking and parallel parking.
