Stage 2: Innovation and Assessment Requirements

Strategic Actions associated with this stage. This stream will collate the overall and detailed user needs for the innovation. These will be used to develop the pilot’s functional requirements or viewpoint, its physical context and the associated communication requirements. This step will utilise the user needs, collated within Stage 1 – aims and objectives, to develop a series of statements defining the requirements for the innovation. This step defines the functionality needed by the innovation to fulfil the requirements This step defines how the functionalities can be grouped into physical locations to form implementable innovation to fulfil the requirements This step, developed from the physical viewpoint, describes the communications links needed to provide implementable innovation and fulfil the requirements. This step, developed from the functional, physical and communications viewpoint, estimates the likely cost of implementing the innovation within the trial. Consideration may also be given to the potential total costs of implementing the innovation across the wider HA network following a successful assessment. The purpose of this stream is to determine key performance indicators (KPIs) for the pilot and develop the overall test methodology to assess these indicators. This stream will also consider the various impacts of the innovation and the likely cost of the overall assessment process. The extent and the practicality of the range of data collection issues would also be addressed. This step considers and determines the key performance indicators (KPIs) to be monitored by the pilot against which the impact of the innovation will be assessed. This step defines the methodology that will be used to measure and quantify the performance indicators defined in step 2.2.1. This step considers and estimates the impact that is anticipated through the implementation of the innovation in the pilot. This step estimates the likely cost of the assessment of the innovation within the pilot. The third stream in this stage is site selection. This includes developing the criteria for the consideration of the pilot site, traffic data analysis, health and safety assessment, environmental impact analysis and site identification. This step develops the criteria required to be fulfilled by the pilot site This step applies the criteria defined in step 2.3.1 to locations on the HA network or off road sites to identify the location of the pilot. After the completion of all three streams within Stage 2, consideration must be given to the overall viability and programming of the pilot. This will balance the estimated costs and impacts of the innovation itself, the assessment framework and the pilot location, identifying alternative procurement routes to ensure these provide flexibility for potential enhancements typically needed in pilots. This will be summarised within the full business case validating the assumptions made to support the continued investment within the pilot. Typical outputs that might be expected from this stage.

Stream 2.1 - Innovation

This stream will provide a clear and detailed indication about what the innovation will achieve through a series of concise, complete, attainable, unambiguous and verifiable statements. These statements will build upon the user needs analysis carried out during Stage 1 which clearly defined the user requirements for the innovation. It may be necessary to revisit the user needs determined though Stage 1 to confirm their continued applicability, should for example, delays have occurred between the completion of Stage 1 and the authorisation to commence Stage 2 or the innovation boundaries may have altered. When a clear set of innovation requirements have been developed, cost estimates for its implementation can be prepared and reviewed. It will also assist in any subsequent configuration management required for pilots investigating ITS developments.

The requirements documents will provide the definition of what the stakeholders want the innovation to provide in terms of the services to be delivered and any constraints to be placed on the delivery of these services. This will also include ensuring that the innovation aligns with the overall HA strategy and vision.

By defining the innovation requirements in this manner it will make sure that all parties, including stakeholders and implementers, have the same understanding of the innovation. This will lead to a successful pilot and enable the concept of the innovation to be more readily implemented on the HA network.
