- Create an inter-departmental freight unit within the city of Durban that can bundle expertise and act as a one-stop shop for freight-related issues in the city. This unit could act as a vehicle to improve coordination on freight transport and engage in joint planning, aligning various actors including Transnet, SANRAL, the national and provincial departments of Transportation and the various departments within the city of Durban.
- Increase the autonomy of TNPA and streamline decision-making procedures within Transnet. This includes more financial autonomy, e.g. by creating a separate fund at the disposal for TNPA for port infrastructure and maintenance.
- Focus performance indicators on the performance of the whole supply chain. Currently much focus seems to be on part of the picture (e.g. crane productivity) without much consideration for (and sometimes even at the detriment of) other indicators.
- Undertake a comprehensive environmental port impact study and implement green-port mitigation policies if necessary

Reporting on Serious Road Traffic Casualties
IRTAD, Policy Insights,
1 December 2011
- A complete picture of casualty totals from road crashes is needed to fully assess the consequences of road crashes and monitor progress.
- Injury information should complement information on fatal crashes to give a fuller picture of road crashes. Information on injuries should become more important for international comparisons.
- Police data should remain the main source for road crash statistics. However, because of underreporting problems and possible bias (for example with differing rates of reporting by vehicle type), police data should be complemented by hospital data, which are the next most useful source.
- The data from hospital emergency departments, available in some countries, should be monitored regularly and researched to determine if they might shed more light on road casualties.
- The assessment of the severity of injuries should preferably be done by medical professionals, and not by the police officer at the scene of the crash.
- Medical staff should be trained in order to systematically classify (road traffic) injuries using ICD International Classification of Diseases and to assess severities with indices such as the Abbreviated Injury Scale (AIS) or the Maximum Abbreviated Injury (MAIS). This information -- without personal information -- should be made easily available for statistical purposes, policymaking and research.
- Besides police data and hospital data, other data sources are available. These have a limited value on their own, and cannot replace police or hospital data, but can be used to build a more balanced and comprehensive picture, to enrich the main data sources, and as a quality check.
- For linking data, the deterministic method is preferred if a unique personal identifier is available; otherwise the probabilistic method is a good alternative.
- The six assumptions needed to use the capture-recapture method must be considered carefully. Using this method combined with linking police and hospital data may be appropriate to give a fuller picture of road casualties.
- Having an internationally agreed definition of “serious” injuries will help the safety research community to better understand the consequences of road crashes and to monitor progress. Given the existing knowledge and practices, IRTAD proposes to define a ‘seriously injured road casualty’ as a person with injuries assessed at level 3 or more on the Maximum Abbreviated Injury Scale i.e. "MAIS3+".
