OFF-STREET PARKING AND ACCESS CONTROL REGULATIONS
Effective on: 1/1/1901
When any combination of these types of parking is used (facing the same aisle) the most restricted aisle or access drive width requirements shall prevail. In addition, a two (2) foot overhang may be permitted on the external sides of a parking area.
If the width of the parking space is increased over nine (9) feet, the drive aisle width can be decreased proportionally (two (2) foot width in drive aisle per one (1) foot increase in space width) except that a drive aisle for two-way traffic may not be decreased below twenty (20) feet in width and a drive aisle for one-way traffic may not be decreased below eleven (11) feet in width.

| Notes: D=Distance along major road from access point to allow vehicle to enter safely. Figures given are measured from a vehicle ten (10) feet back of the pavement edge. Figures given are in feet. Values are for urban conditions. On rural streets, distances are to be increased by ten (10) percent to allow for greater reaction time. The sight distances apply when street grades are zero (0) percent to three (3) percent, either up or down. When an upgrade is steeper than three (3) percent, adjustments are to be made to compensate for the longer time required to reach the speed of highway traffic. The time is less than shown when the highway is descending. Adjustment factors apply to grades only in that portion of the road between the access points and the downstream point at which a vehicle emerging from the access points has been able to accelerate to within ten (10) miles per hour of the route speed. When the street, in the section to be used for acceleration after leaving the access point, ascends at three (3) percent to four (4) percent, then sight distances in the direction of approaching ascending traffic are to be increased by a factor of 1.4. When the access point ascends at five (5) percent to six (6) percent, sight distances should be increased by a factor of 1.7. When the street, in the section to be used for acceleration after leaving the access point, descends at three (3) percent to four (4) percent, then sight distances in the direction of approaching descending traffic are to be reduced by a factor of 0.6. If the road descends at five (5) percent to six (6) percent, sight distances should be reduced by a factor of 0.5. When the criteria for sight distances to the right cannot be met, the need can be eliminated by prohibiting left turns by exiting vehicles. | ||||||||||||||||||||

| Notes: D=Distance along major road from access point to allow vehicle to enter safely. Figures given are measured from a vehicle ten (10) feet back of the pavement edge. Figures given are in feet. Values are for urban conditions. On rural streets, distances are to be increased by ten (10) percent to allow for greater reaction time. The sight distances apply when street grades are zero (0) percent to three (3) percent, either up or down. When an upgrade is steeper than three (3) percent, adjustments are to be made to compensate for the longer time required to reach the speed of highway traffic. The time is less than shown when the highway is descending. Adjustment factors apply to grades only in that portion of the road between the access points and the downstream point at which a vehicle emerging from the access points has been able to accelerate to within ten (10) miles per hour of the route speed. When the street, in the section to be used for acceleration after leaving the access point, ascends at three (3) percent to four (4) percent, then sight distances in the direction of approaching ascending traffic are to be increased by a factor of 1.4. When the access point ascends at five (5) percent to six (6) percent, sight distances should be increased by a factor of 1.7. When the street, in the section to be used for acceleration after leaving the access point, descends at three (3) percent to four (4) percent, then sight distances in the direction of approaching descending traffic are to be reduced by a factor of 0.6. If the road descends at five (5) percent to six (6) percent, sight distances should be reduced by a factor of 0.5. When the criteria for sight distances to the right cannot be met, the need can be eliminated by prohibiting left turns by exiting vehicles. | ||||||||||||||||||||

OFF-STREET PARKING AND ACCESS CONTROL REGULATIONS
Effective on: 1/1/1901
When any combination of these types of parking is used (facing the same aisle) the most restricted aisle or access drive width requirements shall prevail. In addition, a two (2) foot overhang may be permitted on the external sides of a parking area.
If the width of the parking space is increased over nine (9) feet, the drive aisle width can be decreased proportionally (two (2) foot width in drive aisle per one (1) foot increase in space width) except that a drive aisle for two-way traffic may not be decreased below twenty (20) feet in width and a drive aisle for one-way traffic may not be decreased below eleven (11) feet in width.

| Notes: D=Distance along major road from access point to allow vehicle to enter safely. Figures given are measured from a vehicle ten (10) feet back of the pavement edge. Figures given are in feet. Values are for urban conditions. On rural streets, distances are to be increased by ten (10) percent to allow for greater reaction time. The sight distances apply when street grades are zero (0) percent to three (3) percent, either up or down. When an upgrade is steeper than three (3) percent, adjustments are to be made to compensate for the longer time required to reach the speed of highway traffic. The time is less than shown when the highway is descending. Adjustment factors apply to grades only in that portion of the road between the access points and the downstream point at which a vehicle emerging from the access points has been able to accelerate to within ten (10) miles per hour of the route speed. When the street, in the section to be used for acceleration after leaving the access point, ascends at three (3) percent to four (4) percent, then sight distances in the direction of approaching ascending traffic are to be increased by a factor of 1.4. When the access point ascends at five (5) percent to six (6) percent, sight distances should be increased by a factor of 1.7. When the street, in the section to be used for acceleration after leaving the access point, descends at three (3) percent to four (4) percent, then sight distances in the direction of approaching descending traffic are to be reduced by a factor of 0.6. If the road descends at five (5) percent to six (6) percent, sight distances should be reduced by a factor of 0.5. When the criteria for sight distances to the right cannot be met, the need can be eliminated by prohibiting left turns by exiting vehicles. | ||||||||||||||||||||

| Notes: S=Sight distance along major route to safely turn left into access point. Figures given are measured from a vehicle ten (10) feet back of the pavement edge. Figures given are in feet. Values are for urban conditions. On rural streets, distances are to be increased by ten (10) percent to allow for greater reaction time. The sight distances apply when street grades are zero (0) percent to three (3) percent, either up or down. When an upgrade is steeper than three (3) percent, adjustments are to be made to compensate for the longer time required to reach the speed of highway traffic. The time is less than shown when the highway is descending. Adjustment factors apply to grades only in that portion of the road between the access points and the downstream point at which a vehicle emerging from the access points has been able to accelerate to within ten (10) miles per hour of the route speed. When the street, in the section to be used for acceleration after leaving the access point, ascends at three (3) percent to four (4) percent, then sight distances in the direction of approaching ascending traffic are to be increased by a factor of 1.4. When the access point ascends at five (5) percent to six (6) percent, sight distances should be increased by a factor of 1.7. When the street, in the section to be used for acceleration after leaving the access point, descends at three (3) percent to four (4) percent, then sight distances in the direction of approaching descending traffic are to be reduced by a factor of 0.6. If the road descends at five (5) percent to six (6) percent, sight distances should be reduced by a factor of 0.5. When the criteria for sight distances to the right cannot be met, the need can be eliminated by prohibiting left turns by exiting vehicles. | |||||||||||||||
