• • Task Four: Traffic Control Signs and Pavement Markings. Approximately 70 • miles of city streets, 365 intersections, and the areas around four (4) school sites will be inventoried for warning and regulatory traffic control sign and pavement marking installations. These installations will be evaluated as to their applicability of purpose and conformance with the Uniform Manual requirements and the City's traffic ordinances. Improvements in sign placement and marking will be recommended where deficiencies are revealed during the field inventory and where needed as determined in the accident, signalization, and other analyses performed as a part of this study. Task Five: Traffic Accidents. On the basis of City furnished accident spot. maps indicating the location of all accidents occurring within the La Porte city limits (approximately 380 accidents per year), accidents which have occurred during • the last thre e years will be reviewed, ranked and analyzed to identify sites with five (5) or more accidents per year. Collision diagrams will be prepared from City furnished accident records for the off highway system locations averaging five (5) or more accidents per year to depict graphically the involved vehicle movements and the apparent causative factors. An analysis will be made to determine if the accident patterns are sus- ceptible to correction through changes in the control devices, roadway geometrics, markings, etc. A maximum of seven (7) high accident locations will be analyzed. The accident reporting and coding procedures will be reviewed and recommendations formulated to provide for efficient data retrieval and analysis. Traffic improvement recommendations which result from the accident i analyses and the estimated cost of these im rovements will p be summarized. Task Six: Truck Routes. On the basis of data developed in other tasks, dis- cussions with City officials, and field observations, a network of through truck routes will be developed. These truck routes, while emphasising traffic safety, will be developed based on minimizing the impact on, or disruption of, neigh- borhoods and developed areas. Truck route signing standards will be prepared and preliminary cost estimates for the improvements necessary to implement the truck routes tabulated. -3 -
