Tandem parking

Tandem parking refers to a parking arrangement where two or more vehicles are parked in a line, one behind the other, in a single parking space or driveway. It is a method used to maximize the use of limited parking space, particularly in situations where there is insufficient space for side-by-side parking.

Tax Increment Financing (TIF)

A public financing tool used by local governments to stimulate economic development and fund public infrastructure projects. It involves capturing and allocating a portion of the increased property tax revenue generated within a designated TIF district to finance the costs associated with the development or redevelopment of the area.


TNC stands for Transportation Network Company. A TNC is a type of company that uses an online platform or mobile application to connect passengers with drivers who provide transportation services using their personal vehicles. TNCs are also commonly known as ridesharing or ride-hailing companies.

Traffic Calming

Traffic calming refers to various strategies and measures implemented to slow down vehicular traffic and make roads safer for pedestrians, cyclists, and residents. The main goal of traffic calming is to create a more livable and walkable environment, reduce the risks of accidents, and improve the overall quality of life in neighborhoods, communities and parking facilities.

Traffic Study

A traffic study is a comprehensive analysis of transportation patterns, traffic flow, and related factors in a specific area or along a particular roadway. It involves collecting data, analyzing it, and making recommendations to improve traffic operations, safety, and efficiency. Traffic studies are conducted by transportation engineers, urban planners, and government agencies to better understand existing traffic conditions and guide future planning and decision-making.

Transient parking

Transient parking refers to short-term parking where patrons pay for the use of a parking space daily, as opposed to long-term (contract) patrons.

Transient traffic

Transient traffic refers to the flow of vehicles or pedestrians that pass through a particular area or location without having a primary destination or purpose within that area. It refers to transient or temporary movement rather than traffic associated with specific destinations or long-term stays.

Transportation demand management (TDM)

Transportation demand management (TDM) is a set of strategies and policies that seek to reduce the number of single-occupancy vehicles on the road and promote more sustainable modes of transportation. TDM aims to manage the demand for transportation by encouraging alternatives to driving alone, such as public transit, biking, walking, carpooling, and telecommuting.

Transit-Oriented Developments

Transit-oriented developments (TODs) are urban planning and development strategies that promote compact, mixed-use communities centered around public transportation hubs. TODs are designed to maximize the convenience and accessibility of public transit, reduce dependence on private vehicles, and create vibrant, sustainable neighborhoods.

Trip Segment Approach to Wayfinding Design

The trip segment approach to wayfinding is a strategy that breaks down a journey or trip into distinct segments or stages, each with its own set of wayfinding instructions. Instead of providing a single continuous set of directions for the entire journey, the trip segment approach focuses on guiding individuals through each specific stage or segment of their trip.

This approach recognizes that complex journeys often involve multiple decision points, landmarks, or changes in direction. By dividing the trip into manageable segments, it allows for clearer and more focused instructions at each stage, reducing the potential for confusion and improving overall navigation.

For example, when navigating a large parking facility, the trip segment approach may involve providing directions from the entrance to the first decision point or landmark. Once the user reaches that point, new instructions are provided for the next segment, leading them to the next decision point or destination within the facility.

The trip segment approach to wayfinding helps users navigate complex environments more effectively by breaking down the journey into smaller, more manageable steps. It enhances clarity, reduces cognitive load, and improves the overall user experience during navigation.

Turning Bay

A turning lane or a dedicated turning lane, is a designated lane on a road that is specifically allocated for vehicles making turns at intersections or driveways. Turning bays are typically added to improve traffic flow, reduce congestion, and enhance safety by separating turning vehicles from through traffic.

Turnover Rate

The number of vehicles using a given space or facility each day, often expressed as a ratio of the total number of vehicles using the facility in a given period to the total number of parking spaces in the facility.

Two-Bay, End-to-End Configuration

A two-bay, end-to-end configuration refers to a specific arrangement of parking spaces where two parking bays or stalls are positioned consecutively in a linear layout, with one bay directly behind the other. In this configuration, vehicles are parked in a single file, end to end.

This configuration is often used in parking lots or parking garages where space is limited, and maximizing the number of parking spaces is a priority. By arranging the parking bays in an end-to-end manner, the available space is utilized efficiently, allowing for a higher density of parked vehicles.

The two-bay configuration means that two vehicles can be parked in the same linear space, with one vehicle behind the other. This arrangement is common in parking facilities with heavy traffic flow or high demand, as it allows for more vehicles to be accommodated in a given area.

It's important to note that this configuration requires careful maneuvering and coordination by drivers when entering and exiting the parking spaces to avoid collisions or obstructions. Additionally, drivers may need to communicate or coordinate with each other to ensure smooth movement within the parking area.

Type I Construction

Type I construction is the most fire-resistant classification. It is characterized by the use of non-combustible materials such as concrete, steel, and masonry for the structural elements. These materials offer a high level of fire resistance and are designed to withstand severe fire conditions. Buildings constructed with

Type I construction include high-rise buildings, skyscrapers, and large commercial or institutional structures. These buildings typically have substantial fire protection systems, such as fire-rated walls, fireproofing materials, and sprinkler systems.

Type II Construction

Type II construction is less fire-resistant compared to Type I construction. It incorporates non-combustible materials for the structural elements but allows for the use of limited combustible materials such as wood in non-structural components. The combustible materials used are required to have specified fire resistance ratings.

Type II construction is commonly seen in commercial buildings, multi-story office buildings, and some residential structures. It provides a balance between fire resistance and construction cost, as it allows for the use of some combustible materials while still maintaining a significant level of fire safety.
