When changes are made to the transportation system, like adding lanes, changing lane allocation, adjusting traffic signal timing, or even replacing an intersection with a roundabout, it is important to understand how these changes will impact all road users: drivers, pedestrians, and bicyclists.

A Traffic Impact Analysis (TIA) study is performed to assess how a new development will affect the surrounding transportation network. Based on this impact, mitigation options are evaluated and selected.

Signal warrants analysis is conducted to determine if a traffic signal is required for controlling traffic operation at an intersection. This analysis is performed in accordance with the Manual on Uniform Traffic Control Devices (MUTCD) and its local variations.

Analyzing transportation networks, primarily private transport, can be done at three resolutions:

Microscopic: At this level, simplified mathematical models of driving behavior control the movement…

Transit can be studied from the perspective of demand (ridership), supply (service), and operation.

Global transit feed specification (GTFS) files and walk network data are the primary sources for creating the network and timetable used in transit analysis.

Parking studies help to create a balance between the number of parking spots and vehicular travel demand, preventing parking searches from worsening traffic congestion.

To perform a parking study, the number of parking spaces available is classified based on…

To effectively plan for the movement of goods, it's essential to understand and predict future freight growth, technological advancements, freight movement regulations, and the transportation system's response to these changes. Therefore, freight models hold significant importance in transportation planning.

Traffic and revenue studies are crucial for thoroughly evaluating investments and estimating revenue for tolled facilities. These studies are especially vital for public-private partnerships (P3s), as the private sector requires significant clarity before committing. 

Electric vehicles (EVs) represent the future of road transportation, offering substantial environmental benefits. Governments are actively promoting the transition to EVs through consumer incentives and support for authorities to build the necessary infrastructure. A critical component of this shift is the widespread availability of charging stations.

Safety analysis typically begins with the examination of historical crash data, usually spanning a period of 3 to 5 years prior to the analysis. GIS tools provide a suitable platform for analyzing this data, as crashes can be allocated to network objects (road segments or intersections), facilitating more streamlined analysis at each specific point.
