RHD Operational Procedure Ė Technical Services Wing
Road Design and Safety - Road Safety Division
OP/RDS/3.3 - Preparation of Annual Road Safety Engineering Report
Purpose and Scope :

The Annual Road Safety Engineering Report provides a statement of the safety performance of the RHD road network with analysis of the road safety condition of the various highways and roads, which are under the jurisdiction of the RHD. The Annual Report may be divided into three sections, namely National and Regional Highways; Feeder and District Roads (under the RHD's jurisdiction); and Bridges and Culverts.

This procedure describes the process for the production of an Annual Road Safety Engineering Report, the content of which is outlined in the methodology below.
Definitions :

RSC - Road Safety Cell BRTA. The RSC is the custodian of the National RTA Database. The contact details for matters relating to the RTA Database are: The Manager, Road Safety Cell, House 10A, Road 25A, Banani, Dhaka. Attention: Accident Data Analyst.

The meaning of acronyms used for common technical terms are described in the glossary at the beginning of this Manual. Other acronyms used in this procedure are:

RTA - Road traffic accident.
Responsibility :

Additional Chief Engineer - Technical Services Wing - The ACE-TSW is the initial recipient of the Annual Road Safety Engineering Report. The ACE-TSW is responsible for distributing the Report to the Chief Engineer, to all Zone ACEs and to all Wing ACEs and for requesting the appropriate persons to implement the Reportís recommendations.

Superintending Engineer - Road Design & Safety Circle - Responsible for instigating the instruction to prepare the Annual Road Safety Engineering Report, and approves the final draft for issue and distribution.

Executive Engineer - Road Safety Division - Receives the instruction to prepare an Annual Road Safety Engineering Report. Directs and is responsible for the collection of data, preparation of the report, itís editing and final completion. The EE will assign the SDE-RSD and/or an AE-RSD to complete tasks as necessary.
Method :


In February each year, the SE-RDS should direct the EE-RSD to prepare the Annual Road Safety Engineering Report for the previous annual period. A guide to the contents of the report is contained in Section 4.3 below.


Preparation of the report includes the collection of RTA data from the RSC (refer RHD Operational Procedure OP/RDS/3.1) and the collection of road and traffic data from other Circles within the RHD (the Planning & Maintenance Wing, HDM Circle and Planning & Programming Circle, and the Bridge Management Wing, Planning & Data Circle).


The data is to be analysed and assembled into various tables to illustrate

(a) the safety performance of the RHD road network, and

(b) the safety condition of the various highways and roads which are under the RHDís jurisdiction.

Safety performance can be demonstrated as a summary of the total number of casualty RTAs which occurred during the reporting period on all National and Regional Highways and feeder roads which are under the jurisdiction of the RHD. The summary, which can be broken down into Zones, may also include a record of the number of fatalities and the number of persons injured.

Annual trends in the safety performance can be reported by comparing the number of RTAs in the reporting year with the number recorded in previous years.

The Report can also summarise casualty RTAs by accident features and factors such as type of collision, type of vehicle involved, etc., with comment on the significance of the information for targeting road safety initiatives.

By combining RTA data with traffic data, accident exposure and accident rates can be established for road sections within each Zone. This will facilitate the selection of Zones and road sections for the planning of road safety initiatives and interventions to maximise the effectiveness of such measures in terms of accident reduction.

The safety condition of the highways and roads which are under the jurisdiction of the RHD can be reported by tabulating the RTA data conjunction with traffic data and road carriageway data. The proportion of roads which achieve the design standard can be reported and sub-standard sections can be identified. The Geometric Design Standards for RHD roads specifies the standards for several cross-section elements of which the following are significant to road safety: carriageway (lane) width; paved shoulder width; verge width; traffic volume (as proportion of design capacity); NMV/MV ratio; and NMV volume.

The outcome of the evaluation of the safety performance and safety condition of the RHD road network will be the selection of road sections warranting further analysis for inclusion in future road safety improvement programmes. The Report can list this selection with comments and recommendations for future action.

The Report should also contain a summary of the current road safety improvement programme with comments and recommendations as appropriate.

The final draft of the Report is to be submitted for comment before the end of March.


Following approval of the final draft, the Report is to be issued and distributed before the end of April. Refer Section 3 above for directions on distribution.
