limit (LSL)” and “initial specification limit (ISL)” is defined in ISO 3534-3. Introduction ============ When the number of parking spaces is limited, cars often park in a row in the car park. In this paper, we consider the arrangement of cars on a row as a spatial point process. A characteristic length of the process is the distance between adjacent cars. This length can be measured in various ways. The first type of measurement is the space between adjacent cars; this is the car distance and we use the term *car distance* for the distance between adjacent cars. Another measurement is the length of the two lines of cars; we use the term *line distance*. In an ideal parking layout, there is one car in every space. It is convenient to call the spaces where no cars are found *vacant spaces*. In a parking layout with more than one row, the ideal layout is obtained by drawing straight lines, parallel to the wall, so that the total length of these lines is the same as the length of the available parking places in the parking layout. In practice, an approximate layout is drawn. In some parking lots the straight lines for the ideal layout do not fit in the parking lot as they are too long. In other parking lots, the straight lines are not the same size as the parking places. In both cases, the ideal layout will not fit the real parking layout. The ratio between the car distance and the ideal car distance is called the *car packing density*. When the car packing density is low, the ideal parking layout has a large empty space in front of the line of cars. When the car packing density is high, the ideal parking layout is in good order. The total length of all lines of cars is called the line length. When the line length is the same as the total available parking space, we say that the parking layout is *ideal*. We first consider the area in front of the car in relation to the parking place where the car is parked. We introduce the notion of the car area, the line area and the vacancy area. The car area is the area in front of the car which is not occupied by other cars. The line area is the area in front of the line of cars and which is not occupied by cars. The vacancy area is the area in front of the line of cars which is not occupied by cars. We study the statistical properties of these
