The Miller classification of orientation: transportation is a system used to categorize individuals based on their preferred mode of transportation. This classification system was developed by researcher George Miller in the 1970s and is often used in transportation planning and research.
The Miller classification system divides individuals into four categories based on their transportation preferences:
1. Car-oriented individuals: These individuals prefer to travel by car and typically rely on their own vehicle for most of their transportation needs. They may prioritize convenience, flexibility, and privacy when choosing their mode of transportation.
2. Transit-oriented individuals: These individuals prefer to use public transportation, such as buses, trains, or subways, for their transportation needs. They may prioritize cost, environmental concerns, or the ability to avoid traffic congestion when choosing their mode of transportation.
3. Walk-oriented individuals: These individuals prefer to walk or bike for their transportation needs, either for exercise, environmental reasons, or convenience. They may prioritize health, sustainability, or the ability to avoid parking and traffic issues when choosing their mode of transportation.
4. Mixed-mode individuals: These individuals do not have a strong preference for any one mode of transportation and may use a combination of cars, public transportation, walking, or biking depending on the situation. They may prioritize flexibility, convenience, or cost-effectiveness when choosing their mode of transportation.
By understanding individuals' transportation preferences and behaviors, transportation planners and policymakers can better design and implement transportation systems that meet the needs of different types of travelers.

Miller Classification of Orientation: Transportation
The Miller classification is a system used to categorize rock samples based on their orientation relative to the direction of transportation. It is primarily used in sedimentology to interpret the depositional environment and transport conditions of sedimentary rocks.
The classification is based on the relative angle between the following three parameters:
- Grain fabric: The alignment of individual grains within the rock.
- Bedform orientation: The orientation of sedimentary structures (e.g., cross-beds, ripple marks) within the rock.
- Paleocurrent direction: The inferred direction of sediment transport during deposition.
Transportation Types
The Miller classification divides sedimentary rocks into five transportation types based on their orientation characteristics:
1. Parallel Orientation:
- Grain fabric and bedform orientation parallel to the paleocurrent direction.
- Indicates unidirectional transport under high-energy conditions.
2. Subparallel Orientation:
- Grain fabric and bedform orientation are mostly parallel to the paleocurrent direction but with some deviations.
- Suggests deposition in a high-energy environment with occasional changes in flow direction.
3. Cross Orientation:
- Grain fabric perpendicular to the paleocurrent direction.
- Indicates deposition under low-energy conditions with bidirectional or multidirectional transport.
4. Climbed Orientation:
- Grain fabric and bedform orientation are inclined in the direction of the paleocurrent.
- Forms in high-energy environments where sediment is deposited on the stoss side of dunes or ripples.
5. Random Orientation:
- No consistent orientation of grain fabric or bedform orientation.
- Indicates deposition in a low-energy environment with no preferred transport direction.
Application in Sedimentology
The Miller classification of orientation helps sedimentologists:
- Determine the paleocurrent direction and depositional environment of sedimentary rocks.
- Understand the hydrodynamic conditions during sediment transport.
- Reconstruct ancient fluvial, deltaic, and coastal systems.
- Interpret the sequence of sedimentary processes that have occurred in a basin.
