Introduction

How can the CT FMS help to better understand pedestrian accidents and activity on Cape Town’s freeways?

  • Background to FMS
  • Historically Road Authorities focused
  • nly on infrastructure to meet growing

traffic needs

  • Shift towards Network Management

and Operations

  • Technology to Optimize use of the

Network

  • Intelligent Transportation Systems (ITS)
  • Freeway Management System (FMS)
  • 1. Overview of the CT FMS
  • 1. Overview of the CT FMS ..cont
  • First FMS deployed on 20 km section of Ben

Schoemann Highway and launched by Minister of Transport in 2006

  • Since then;

– Expanded in Gauteng +/- 220 km – KZN +/- 100 km – Western Cape +/- 155 km

Benefits of FMS

Accident happens

  • Traffic

flow disrupted Accident reported Emergency Services dispatched Arrive on scene Leave scene Traffic flow back to normal

Reduce length of Incident Timeline Life Death Minimise Road User Costs Incident Timeline

  • Benchmarking and Improving on Incident

Management Systems – E.g. Accurate Measurement of Response Times for Emergency Vehicles – Accurate and comprehensive data collection – Video Archives useful Training Material, Debriefings

  • Summary

Ability to understand the nature, location and extent of pedestrian activity can give guidance to most appropriate engineering, enforcement and education interventions

  • 4. CCTV Surveillance and Footage Usage
  • CCTV pedestrian accident footage can provide

valuable insight into factors that contribute to pedestrian accidents on freeways

  • Pedestrian crossing: Risk taking
  • Def. Risk: “the appraised likelihood of a negative
  • utcome for behaviour" (Zuckerman, 1994)
  • Appraised likelihood
  • Subjective
  • Learned experiences
  • Perceived skill / ability
  • Knowledge of the environment
  • Attitude / mental state
  • Poor appraisal of likelihood = outcome is unknown
  • Case One: Experience – changing environment
  • Case Two: Less Experience – over estimation of

skill / ability

  • Case Three: Limited knowledge, skill, experience
  • 4. CCTV Surveillance and Footage Usage
  • Pedestrian crossings: Risk taking….continued
  • Group Crossing Activity
  • Case Four
  • Case Five
  • Case Six
  • Driver Behaviour ?????
  • Should we be teaching motorist how to

behave when pedestrian are prominent

  • n freeways
  • slow down
  • no lane changing

Way Forward

  • A CT FMS Steering Committee has been formed

with representation from the three road authorities, traffic and emergency services.

  • This Steering Committee is task with identifying

and addressing hazardous locations on the freeways.

  • The pedestrian accident and activity trend data

is guiding engineering, enforcement and education interventions.

  • Further investigate research opportunities using

CCTV footage to better under pedestrian risk taking.
