Towards safer roads in developing countries : a guide for planners and engineers. On behalf of and in association with the Transport and Road Research Laboratory TRRL TRL, Overseas Unit.

In this document the different strategies involved in planning and designing road networks are outlined, and safety conscious design principles are given. Guidance on accident prevention is given by highlighting the key safety related factors which need to be incorporated when planning, designing and operating road networks. Advice is given on accident reduction by showing how hazardous locations can be analysed and the types of countermeasures which can be used to reduce accidents at such locations. It includes information on the TRRL microcomputer accident analysis package. This guide makes use of existing geometric and traffic engineering design practices in a number of developing and developed countries. The main reference documents used in preparing the guide are listed in Appendix A. This guide is based in part, however, on the practical experience gained from a large number of professionals working in developing countries, rather than stricktly adhering to design standards in use in the developed world.
