  • Trip Generation

    Use any baseline site trip generation data to estimate person and modal trips at any study site regardless of its development context.

    Analyze multiple development scenarios, define each study site land use with custom modes and different trip generation database, and instantly view data statistics before choosing the best IV and method.

    Estimate internal capture based on the latest guidelines from NCHRP and ITE. Reduce trips such as pass-by, linked, transferred, and diverted trips to estimate appropriate non-pass-by trips. Also, separate trips by on-road and off-road to analyze the network with proper demand.

    Besides, OTISS lets you analyze single trips made by multiple modes within the study area.

  • Graph Look Up

    Tired of referring to hard copies trip generation manuals? Try OTISS and pull out trip rates, equations and view graphs just in couple of clicks and access the data from anywhere you go.

    Look up graphs of not only ITE Trip Generation data but also the local data you collect. Overlay or combine local data on ITE trip generation data to improve the quality of the data.

    Apply filters and regenerate average rates and equations. Also, create your own graphs and print them for presentations.

    Interact with graphs using zoom in/out, setting IV size to check estimated trips.

  • Local Data

    Create your own trip generation database and store it securely on OTISS cloud server. Add custom land-use codes, independent variables and new time periods to produce average rates, equations and graphs just like in ITE Trip Generation Manual.

    Access your data on the go and share it with your team within your organization enhancing productivity and collaboration. Generate trips by referring to your own standard trip rates or equations.

    Overlay & combine local data with other established data to statistically improve the data quality and trip parameters.

  • Network Analysis

    Introduced a new capability to perform spatial analysis of trips by graphically identifying study area, site, land uses, zones and by building road network.

    Graphically analyze existing and background conditions, distribute trips automatically based on various methods and let OTISS find possible routes to assign the trips on appropriate routes.

    Display turning volume diagrams for not only driveway intersections but also other nearby impact prone intersections.

    Besides, analyze trips made through various waypoints such as on-street parking, outside garage parking, bus-stops, taxi stands, subway stations etc.


ADDITIONAL FEATURES IN OTISS

ITE Trip Generation Data Submission

Any traffic engineer can create a limited free account in OTISS to access the online trip generation data submission form. In the past, you might have submitted trip generation data to ITE by faxing the forms. Now, you can fill the online form in OTISS and submit studies to ITE for review and approval. This activity is important to ITE as it will improve the quality of studies (e.g. more recent studies for current land uses, new studies for new land uses, region-specific studies). Your participation is encouraged.


Overlay and Combine Data

Private Data Sets can be combined with the ITE Trip Generation Data (8th or 9th Edition) in Graph Look Up. Unlike the overlay option in the previous versions, the combine option not only overlays the data but also consolidates that data and generates new curves, average rates, equations and directional splits. User will also have option to apply filters on the combined data. This functionality helps you to enhance or verify statistics when data is aggregated.


Preview of Data Statistics

Before generating trips for any land use, users have an ability to choose the appropriate independent variable and method based on data statistics preview. It provides the list of independent variables available for a land use, number studies conducted under each IV, average size, R2, and standard deviation to help user to choose best IV and method which in turn enhance the quality of analysis.


Custom Trip Rates

Although average rates & equations are provided by private data sets, user will have an additional capability to define their own average rates and equations. This will help them make their professional judgement on rates and equations which do not seem to be calculated rightly based on the data collected. Users can use custom trip rate for any land use in project analysis that uses private data sets as the baseline data source. The custom rate can be defined in the form of average rate, linear or log-normal equation.


Import Private Data

With any local data that you have collected, you can easily import this set of data from a CSV format to OTISS. Once the private data set is imported, OTISS will help you analyze the studies to determine the directional distribution of entering and existing traffic, average trip rates, the fitted curve equation, range of rates and standard deviation. It makes it possible to visualizing how local data compares with the ITE land uses.


Sharing Projects Online

Once you have completed a project analysis in OTISS, you are now able to share this project with another OTISS user. If your organization has multiple OTISS user accounts, you can indicate which user you would like to share the project with. In addition, you can define the access level of the shared project to be read only or editable. It makes collaboration possible with peer reviewers or supervisors. In addition, it is also possible to share a project with any OTISS users (External Reviewer) outside for your organization


Scenario Based Analysis

Split the project analysis in to multiple development scenarios by defining each scenario with different inputs. Use ITE time periods or define your own time period to analyze the project for particular scenario. Work on one scenario and copy to make another scenario quickly. View brief scenario information on every page of project analysis.


New Internal Capture

Estimate internal person and modal trips between any two land uses using methodology recommended by NCHRP Report 684 and ITE Trip Generation Handbook 3rd Edition. Although standard unconstrained internal person trips capture rates are not available for land uses, OTISS provides you an ability to generate internal trips using custom values. Unlike the old version, version 4.0 introduces a new GUI to help you understand the process quickly. Users can not only estimate internal trips for isolated mixed land use developments but also mixed land use developments located in urban infills where external walk and bike trips are expected.


Analyze Single Trips Made by Multiple Modes

It is quite normal in urban sites where people travel in multiple modes to reach destinations. If user has appropriate mode share information at study site, OTISS can generate all modal trips made by single trips. Further, it provides an ability to spatially analyze (in network analysis feature) these trips and assigns the trips properly to the designated routes.


Configure and Export Reports to Excel

Export only what information you are looking for in the final results. OTISS is currently capable of exporting two types of reports; Trip Generation and Network Analysis. Trip Generation report provides trips estimated by each mode and land use both in person and modal trips wherever applicable. Similarly, Network Analysis reports provide turning volumes at analyzing intersections and person trips demand at analyzing waypoints within the study area.
