Nabil has comprehensive experience in the specification, development, implementation and operation of intelligent transport systems. He holds three relevant university degrees and has a keen interest in the trends which shape the development of transportation worldwide.

He joined Rapp Trans UK in the role of Managing Director in September 2009, bringing a new dimension to the core skill set, and focusing on sustainable growth.

Prior to joining Rapp he spent the first 7 years of his career with TRL Limited getting a good grounding in transport policy and research-led innovation. His portfolio of research was later accredited with a PhD from the University of Southampton.

He then invested six years with the Mouchel Group, making a pioneering contribution to the M42 Active Traffic Management, which was further endorsed by his registration as a Chartered Engineer. He was also responsible for implementation of an intelligence based approach, to prioritise critical spending for the M25 London Orbital. During this period, he became involved in contract improvement initiatives, and gained significant exposure to procurement models, including DBFO.

Nabil moved to South Africa in early 2008, building relationships with the local industry and participating in high profile projects as an independent advisor. He advised on and co-authored the performance management framework for the Gauteng Open Road Tolling. He was also directly involved with the specification of a pioneering approach to fare collection for Bus Rapid Transit in Johannesburg and Cape Town, using EMV Smart Cards. Based on this experience, he had the privilege of conducting a master class at the ITS South Africa Conference in 2009.


Mark Wedlock - Technical Director

Mark has been involved in the specification and development of ITS services for over 10 years, although primarily focused on road user charging, he has also contributed to the development of in-vehicle and mobile information services, real-time traffic information, real-time bus information systems and has worked with and provided advice to DfT, HMCE, Highways Agency, TfL and European Commission as well as private sector service providers.

Mark has a particular focus on the technical development and specification of road user charging systems. He has been involved in the development and review of the DfT OMIS specifications for DSRC based RUC, was responsible for the design of the Proof of Solution test programmer for LRUC and subsequent trials management at TRL.

Between 2005 and 2008 Mark was a member of the TfL Technology Trials team, responsible for the management of the Design Issues Programme and was a key member of the technical team for TfL DSRC Framework procurement.

During 2009 Mark supported the Department for Transport's involvement in the UK Interoperability Forum and was responsible for leading the development of a number of the Technical Specifications. He is a member of the testing and certification team for the Dutch KMP procurement.


Ken Perrett - Director

Ken provides technical advice for those involved in transport policy development. He has advised on the impacts of major UK transport policies, such as those on light rail, bus deregulation, congestion and HGV charging. Ken is a specialist in intelligent transport systems. He has been involved in ITS policy formation, development of applications and evaluation of their impacts. Ken works within an international environment, providing advice to the European Commission and to other countries.

Ken has a particular focus on road user charging systems, having worked for the past 10 years on all aspects of charging systems, both in the UK and working with other technical experts across Europe on common approaches to charging systems. His key area of expertise is in knowledge of the procedural, contractual, legal and operational aspects of the schemes and on interoperability issues. He has worked on the research programme for supporting road user charging in the UK and provides technical advice on the proposed national lorry road user charging scheme (LRUC). He has also been a technical advisor on risks for the financing of the Austrian lorry toll scheme and on the development of the Australian charging scheme for heavy vehicles.


Bernhard Oehry - Non Executive Director

Bernhard holds a MSc degree in Communications and High Frequency Technology from the Technical University of Vienna, Austria. Bernhard is an expert on the standardised CEN 5.8GHz dedicated short range communications (DSRC) link. He is a member of the project steering committee that was responsible for the planning and implementation of the Swiss Heavy Vehicle Fee system (LSVA). On a number of projects, he has been appointed by the European Commission as Reviewer/Auditor for the annual reviews of transport telematics research projects. He also actively participated in several European Commision research projects.


Ernst Magerl - Senior Consultant

Ernst provides advice in the domains of electronic road user charging and Intelligent Transport Systems. He has design experience in multilane freeflow urban, interurban and classic toll plaza environments. In particular Ernst is able to apply expert knowledge in the area of DSRC technology and central backoffice systems. His skill to deliver in-depth technical analysis combined with his ability to put these results into a larger commercial context enable him to create synergies between engineering and management.

Currently Ernst is giving advice to the Department of Transport on interoperability of EFC systems. He is the author of the Department's top-up specification to EN 15509, and the Core model for Interoperability which he has negotiated with TfL, the M6Toll and the Dartford Crossing as input to the Management Committee of the Interoperability Forum. He also is member of the CEN TC278 PT21 drafting a prEN standard for testing against the requirements of EN 15509.


James Long - Consultant

James gained a distinction for his final thesis investigating the impact of transport policy on the accessibility of the North-East of England. James is currently working as the Deputy Learning Manager for the Road Pricing Demonstrations Project and is involved in capturing and reporting the learning from the Project.

As part of this role, James has been involved in developing, managing and assessing a requirements catalogue; playing a key role in managing the expert group process (including developing briefs on key themes for the project and wider environment and managing experts and stakeholders); developing and implementing approaches to disseminating project outputs and learning to both internal and external stakeholders. This project has developed James' experience in the political, contractual, procedural, commercial, legal and technical aspects of Road User Charging both in the UK and more widely.

James worked on developing the National Technical Framework for ITS in the UK on behalf of the Department for Transport (DfT). This work has involved stakeholder engagement with Local Authorities, the DfT. The Highways Agency and industry. This work has developed James' experience in dealing with the development of systems architecture for ITS as well as gaining experience in the use and application of many forms of ITS.
