TRAFFIX™ is an interactive computer program for IBM PC compatible computers that enables planners and engineers to efficiently:

• Calculate level of service for signalized intersections (using HCM, ICU, Circular 212, SIGCAP and custom methods), unsignalized intersections (HCM 2-way and all-way stop), roundabouts (FHWA) and arterials (HCM)
• Rapidly forecast the traffic impacts of new developments
• Conduct city-wide traffic forecasting studies
• Interactively test different mitigation measures
• Determine traffic impact fees for individual development projects
• Compare base and future traffic scenarios
• Import turn movements from regional travel demand models

The TRAFFIX™ programs allows up to 65,000 intersections, 65,000 gates, and 65,000 zones to be stored in a single database. Traffic volume and level of service results for all intersections are simultaneously updated when development assumptions are changed. TRAFFIX™ generates comprehensive, yet concise and easy-to-read, outputs that are suitable for inclusion in project reports.

What’s new in TRAFFIX™ 7.9 for Windows?

TRAFFIX™ 7.9 includes the following new features:

Basic Program Features
TRAFFIX™ performs four functions critical to the impact evaluation of traffic engineering and land development projects: traffic forecasting, level of service analysis for intersections and arterials, mitigation, and impact fee calculation.

Traffic Forecasting
The user draws a road network on the screen using cursor operated drawing tools. This road network consists of development zones, critical intersections, and gateways where new traffic enters and leaves the study area. The land uses, trip generation rates, and trip distribution percentages are then entered for each development zone. The paths that traffic will use between each development zone and each gateway are drawn on the network.

TRAFFIX™ then generates the hourly traffic (AM and PM peak hours), assigns it to the street system, and calculates the level of service impacts all in one step. The user can request a trip generation report, a trip distribution report, an intersection turning movement report, a link volume report, and more.

Level of Service Analysis

TRAFFIX™ calculates the level of service for signalized intersection using any one of several different methods: 2000, 1997, 1994 and 1985 Highway Capacity Manual (HCM) Planning and Operations, TRB Circular 212 Planning and Operations, two ICU methods, and more. TRAFFIX™ calculates signal timing (green times and cycle lengths) and queue lengths to assist in evaluating signalized intersection operations.

TRAFFIX™ also calculates the intersection level of service for two-way stop controlled intersections using the 1985, 1994, 1997 and 2000 HCM methods; and calculates the intersection level of service for all-way stop controlled intersections using the 1994, 1997 and 2000 HCM methods.

TRAFFIX™ calculates roundabout level of service using the FHWA method.

TRAFFIX™ calculates arterial level of service using the 1985, 1994, 1997 and 2000 HCM methods.

Mitigation

A special "interactive screen" is provided in the program that allows users to quickly test various street improvements and signal timing changes for mitigating impacts to traffic operations at an intersection. Users can quickly identify the critical movements, test mitigation measures, and observe their results.

Impact Fees

TRAFFIX™ can be used to perform impact fee analyses and establish "nexus" requirements since it actually traces the traffic generated by a new development through each critical intersection on the street network. The user enters the total cost of the improvements at each intersection. TRAFFIX™ then calculates the relative share of the intersection improvement costs attributable to each development project. The fees are based upon the estimated number of trips that the development sends through the intersection. The proportionate costs are then added up by TRAFFIX™ to obtain a total traffic impact fee for each proposed development. The result is a fee schedule for each new development project that is based upon its actual traffic impacts.

System Requirements

TRAFFIX™ needs at least a 486 or Pentium (recommended) microprocessor and 64 Mb (128 Mb recommended) RAM to operate properly. Best performance is provided on machines with higher CPU speeds (90 MHz or higher). TRAFFIX™ is a 32-bit program; requiring Windows®95/98/ME/2000/XP or Windows® NT 3.5/4.0. TRAFFIX is not designed to run under Windows® 3.1 or MS-DOS.
