Project: Incident Duration and Other Parameters in INCA: MWay Weather Data

Reference: H133

Last update: 03/02/2005 15:00:25

Objectives

The objective of this research is to gain results that will lead to improved transport modelling advice and to more realistic estimation of the relationship between journey time variability and traffic volumes.

Description

The incident duration appraisal program (INCA) requires updating. This study will take recent data (see also project H016B/C) to revalidate the INCA program. This will comprise of the following:

1. Automatic Number Plate Recognition (ANPR) data;
2. Motorway Incident Detection & Advisory Signing (MIDAS) count data;
3. Motorway Traffic Viewer (MTV) plots & MIDAS speed data;
4. Other count data;
5. Incident data;
6. Weather data
7. Event data;
8. Roadworks data;
9. Carriageway configuration data

Summary of results

  1. The data feeds into parallel research work being carried out by TRL/Arup analysing these data.
    Problems were identified by TRL with the visibility data - and although significant effort was put into resolving these they were not overcome during the research period.
