To shoe location of bottlenecks. To show various control devices like Road Sign, Marking, Signal, speed Breaker, Street Light etc. To find density of Road obstructions (manholes, speed breakers, potholes etc). To find Density of Side roads. To find out the faults of that intersection and making proposals to remove them. To plan for reducing and minimize delay time in intersection. To make some recommendations for the betterment of the existing situation of our study intersection. 7

- 9. Basic Components of Roadway Survey Road, Vehicles, Road Users & Roadway Environment. 9
- 10. Importance of Roadway Condition Study Increase the efficiency and life of roads. Reduces traffic congestion Provide better means for development of infrastructures. To find the need of improvement of a roadway or side walk or any other basic road component. To improvisation of pedestrian or vehicle movement or parking facility. 10
- 12. Potholes A pothole (sometimes called a kettle and known in parts of the Western United States as a chuckhole) is a type of disruption in the surface of a roadway where a portion of the road material has broken away, leaving a hole. 12 Potholes Potholes Accident In a Pothole
- 13. Curbs A curb the edge where a raised pavement/ sidewalk /footpath, road median/central reservation, or roads shoulder/hard shoulder meets an unraised street or other roadway. Curbs may fulfill several functions. Curbs can be used to channel runoff water from rain, or melted snow and ice into storm drains. 13
- 14. Channelization Channelization is an engineering concept which employs the use of secondary roads to separate certain flows of traffic from the main traffic lanes. It is the separation or regulation of conflicting traffic movements into definite paths of travel by traffic islands or pavement marking to facilitate the safe and orderly movements of both vehicles and pedestrians. 14
- 15. Shoulders A hard shoulder, or simply shoulder, is a reserved area by the verge of a road or motorway. Generally it is kept clear of motor vehicle traffic. 15 Shoulders Super Elevation Super elevation is tilting the roadway to help offset centripetal forces developed as the vehicle goes around a curve. Along with friction they are what keep a vehicle from going off the road.
- 16. Link Road A link road is a transport infrastructure road that links other major road transport facilities, often added because of increasing road traffic. They can be controversial, especially if they threaten to destroy natural habitat and green field land 16 Link Road
- 17. Side road A side road or side roadway is a narrow lane found in urban areas, often for pedestrians only, which usually run between or behind the buildings… 17
- 18. Road Marking Road marking is any kind of device or material that is used on a road surface in order to convey official information. They can also be applied in other facilities used by vehicles to mark parking spaces or designate areas for other uses. Road surface markings are used on paved roadways to provide guidance and information to drivers and pedestrians. Uniformity of the markings is an important factor in minimizing confusion and uncertainty about their meaning, and efforts exist to standardize such markings across borders. However, countries and areas categorize and specify road surface markings in different ways. Road surface markings are either mechanical, non-mechanical, or temporary. 18
- 19. Road Signs Traffic signs or road signs are signs are shown at the side of or above roads to give instructions or provide information to road users. The earliest signs were simple wooden or stone milestones. Later, signs with 19
- 20. Road Signals A road signal for directing vehicular traffic by means of colored lights, typically red for stop, green for go, and yellow for proceed with caution. Also called stoplight, traffic signal. 20
- 21. METHODOLOGY Reconnaissance survey of study area. Chose Study Method Manual Walking Method Chose Data Collection Method Indirect Method Chose equipment for Ensure other key features Perform necessary office preparations. Select proper observer location. Label data sheets and record observations. 21

- 23. Steps of Methodology Reconnaissance Survey Type of Roadway Condition Method Manual Roadway Condition Survey Manual Roadway Condition Survey Instruments Vehicle Based automatic roadway condition survey Vehicles for automatic roadway condition survey Choice of Mechanism For Roadway Survey Chose Procedure of Work 23
- 24. Reconnaissance survey Reconnaissance survey was performed- To get an idea about the situation of the roadway. To make easy and understandable final roadway condition survey. To select what type of method for field work to be followed 24
- 25. Roadway Condition Survey Methods 25 Roadway Condition Survey Manual Method Vehicle Based Automatic Method Walking survey Windshield Survey Walking + Windshield Survey
- 26. Manual Roadway Condition Survey Instruments 26 Measuring tape (small) Measuring tape (large) Odometer camera
- 27. Roadway Condition Summary 27 Survey Date 15th & 17th December, 2014 Survey Time Between 7:00am to 8:00pm (Day & Night) Survey route Russell Square to Green Road Survey Method Manual Measurement Measuring Equipment A pair of 15 meter tape & 5 meter tape Camera Nokia 5MP mobile & Samsung HD Camera Number of Enumerator 8 person in two groups (1 group each side)
- 28. Working Steps At first we divided our enumerators into two groups. Each group takes different sides. We used tapes for measurements. We counted number & width of side roads, potholes, and street light and observed their physical condition. We collected information about road marking, signs & signals, parking facilities. We listed measurement data of roadway and sidewalk and their present condition. We measured median and opening heights and widths. We also have photographic documentation 28
- 30. Chose The Best Option From Considering all facilities & limitations we chose MANUAL ROADWAY CONDITION SURVEY SYSTEM 30
- 31. Data Analysis 31

- 47. Condition of Roadway Signal
- 48. Obstruction due to trees Condition of Roadway Signal
- 51. Finding s Lots of pot holes on pavement In some segment sidewalk is full of human waste and unusable for pedestrian. Lots of side road causes side friction on main stream vehicle Uneven, dirty & unusable side walk in some road section Lots of small shops found obstructing sidewalk No additional facility for blind pedestrian Poor or no parking facility in some road sections Lots of illegal parking on road side even by the law enforcing forces. Street light condition are good and some solar street light are newly implemented All type of signals are useless. Manual traffic handling of vehicle at intersections by traffic police. Islands are illegally captured, in some places by police box 51
- 52. Limitations Totally manual method. Number of enumerators was 4 persons per group We collected data for some segment at large interval. However if it was possible to collect data for more sections then a better scenario could have been presented. 52
- 53. Recommendation s 53 Pot holes and other obstruction which reduce the traffic speed should be removed. A bus lay by may be applied on both side of this road. Parking facilities should be improved & controlled to reduce side friction. In junctions automatic signaling system might be introduced. Fused street light should be replaced. Worn out or almost worn out road marking & signs should be replaced. Storage of construction materials on roadway should not be allowed. Food shop, nursery, temporary shops are recommended to remove from footpath with their proper compensation. A public toilet may be constructed to stop footpath being unusable due to human waste .
