ANSA develop both adhoc and formal planning tools in
database and program based environments. Systems predominantly use MS Access
and Visual Basic but adhoc systems can be developed using a number of different
development environments. All database systems feature full multi-user
functionality and data can be accessed through web browsers.
Signal Controller
-
Signal Controller
- Signal Controller provides an easy-to-use
universal controller application to control PARAMICS using the Simple Network
Management Protocol (SNMP) interface in both simulation and batch mode. This
includes full and semi VA controllers, with or without demand dependencies,
that can be fully calibrated, be vehicle type dependent, use fixed or variable
cycles, be linked to Fixed Time Plans and be configured over different time
periods. The controller also includes a Keep Clear controller that can be
used to better model Keep Clear boxes.
Transport Manager
-
Transport Manager
- Transport Manager combines three separate systems of
Information Manager, Development Manager and Traveller Manager. Transport
Manager can be used to store and monitor transport data (Information Manager),
can be used to collate data on individual or collections of developments and
indicate potential material impacts (Development Manager), and provide a
forecasting tool to help indicate the impact of transport strategies and plans
on future year traveller choices (Traveller Manager).
-
Information Manager
- Information Manager provides a system for collating and
organising a broad range of transport data items using a database system,
including National Census data. Information Manager also includes a network
development system which allows key features of the transport network to be
catalogued and stored, including plans and photographs. Information Manager
allows data sets to be combined with networks in a Network/Data Scenario
providing a powerful analysis tool to monitor changes in network information.
Network plotting facilities are available from within the application which
allow comparisons between two Network/Data Scenarios, including specific
information to measure the statistical significance of traffic changes. Data
can also be input/output via GIS applications.

Development Manager
-
Development
Manager allows numerous developments to be stored and catalogued, with each
development consisting of a number of units defined by size and type of land
use. Each development unit is associated with trip rates and a trip
distribution, both stored centrally within the system. The distribution
can be based on a simple percentage split or a weighted, unconstrained gravity
model.
Development Manager uses
a two tier geographical zoning system. The Lower Tier represents the
level of detail being considered in a particular study and the Upper Tier can be
used to provide a more appropriate trip distribution. Trip distributions
represented in the Upper Tier are either derived using a wide area zoning system
or using outputs from a more strategic model. Wide area zoning systems
have been developed using Census wards and have allowed long distance trips to
be properly assessed. Strategic model outputs have been used to provide a
template distribution. The distribution used in the Lower Tier is either
translated from the Upper Tier or derived within the Lower Tier itself.
This latter option has included developing gravity models in the Lower Tier or
using distributions associated with similar zones.
Development Manager combines all individual land use units
within each development and then each development within a Development Scenario.
Development Scenarios are output as arrival and departure matrices in either CSV
format or a text format associated with a transport modelling package.
Traveller Manager
Traveller Manager provides a series of traveller
choices that can be arranged in a hierarchical structure and set in future
year scenarios. At the most simple form traveller choices can be based solely
on route choice with more complex models including frequency, destination,
time of day, mode and sub mode choices. Traveller choices can be assessed
using a variety of levels of demand segmentation and using a range of future
socio-economic and demographic scenarios.
Other ANSA Systems
-
Telephone Survey
- Telephone Survey provides a telephone interview system
that can handle large interview teams and caters for statistical sampling
through centrally stored interviewee data. The system features 'high level'
questionnaire coding so that any type of survey can be quickly setup and
subsequently edited by the user. Central storage of data allows monitoring,
system modifications and backups to be easily undertaken during interviewing.
Internal reports help quantify the success and results of surveys, and manage
follow-up calls.
