[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Beacon GPS Background
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],WHY UNCERTAIN?  :  Has been tested only by small scale implementation and simulation studies under ‘laboratory’ conditions. Hence effect of large scale implementation in real world is uncertain. Problem
[object Object],[object Object],[object Object],[object Object],Problem Identify the problem Analyze and compare alternatives Selection & screening of alternatives Develop scenarios Decide on outcomes of interest Specify objectives Implement alternative or policy Monitor and evaluate results  Traditional policymaking
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Adaptive Policymaking Approach Source : Walker et al. 2001 Constraints certain uncertain
Traditional  decisionmaking  versus   Adaptive decisionmaking D1 Today Future   D2 D3 Today Future   Monitor Monitor Monitor D2 D1 D3

Step 2 - Assembling the Basic Policy ,[object Object],[object Object],Policy Specifications :  Urban roads,  Cars  and Young drivers (18-34 years) ,[object Object],[object Object],[object Object],[object Object],[object Object],Dynamic Voluntary ISA is selected to be implemented
Step 3 – Specifying the rest of the Policy Vulnerabilities   Mitigating Actions Signposts Dependence on the system by the users (uncertain) ,[object Object],[object Object],[object Object],[object Object],[object Object],Low user acceptance (uncertain) ,[object Object],[object Object],[object Object],[object Object],[object Object],Reliability of ISA in times of incidental speed limit (certain) Temporary vehicle – roadway communication- beacon Hedging  Actions
