An accrual policy is one where employees earn sick leave over time, with the accrued time carrying over in each year of employment. In general terms (and subject to some exceptions), employees under an accrual plan must earn at least one hour of paid sick leave for each 30 hours of work (the 1:30 schedule).
The most important routes could be anything up to 60 feet (18 m) wide, enough for a full, wide, modern dual carriageway! These great widths can still be seen, even though the modern surfaced roads may only be 5 or 6 m wide, they lie between wide grass verges, showing the original width of the road.
The illustration also shows the distance between vehicles for the three typical street widths. The average width of a vehicle is six feet. The spacing for a car on the 29 foot street is 7.3 feet, or a distance of about 1.3 feet, or 15.5 inches between vehicles, not a comfortable driving distance between vehicles. The 35 foot street proportional spacing is 8.7 feet, a distance of 2.8 feet or 33.6 inches between vehicles. The 39 foot street width spacing is 9.7 feet leaving 3.8 feet or 45.6 inches between vehicles.
