The Term Level Crossing (Also Called a Railroad Crossing, Road Through Railroad, Train Crossing Or Grade Crossing) Is a Crossing
CHAPTER 3 DATA COLLECTION 3.1 Railway Network in Sri Lanka Data obtained from SLR related to the rail network is summarized and illustrated in table given below. Table 3.1 Summary of existing Rail Network Rail Line Length No s . Protected Level Km Crossings Main line 291(Colombo-Badulla) 67 Puttalam line 120(Ragama-Puttalam) 152 KV line 59(Colombo- 69 Avissawella) Matale line 34(Kandy – Matale) 11 Coast line 160 (Colombo- Matara) 189 Trincoalee line 70(Galoya – 23 Trincomalee) Batticaloa line 212(Mahawa- Baticaloa) 34 Nothern line 184(Polgahawela- 78 Vavuniya) Total 623 Source: Sri Lanka Railways. Note: Number of level crossings in above table includes only the controlled crossings. 3.1.1 The systems adopted for data collection The data collection in this research involved field visits, surveys, interviews, collecting data from SLR sources, literature reviews etc. Under field visits around 125 rails crossings were observed in Colombo Area, Southern Province, Upcountry Area, Trincomalee District and photographs were taken at locations contributed for delay as well as in good sections (very few). Special attention was given on main line as it involves multi tracks in most of the locations. Evaluation of parameters influencing delay at level crossings. Page 24 of 62 In addition to the photographs, all the important points / issues related to delay and safety such as surface defects, visibility problem, alignment related issues were noted down in each locations. Random interviews were made with road users, residents of surrounding areas, gate keepers, rail passengers and officials of SLR whenever required. In collecting data especially on approaches (to address alignment related issues) to the crossings in order to ensure the starting delay of vehicles just after the rail gate is open (after the gate closer for rail passing) was also noted down.
